    DISSENTING OPINION
    JUSTICE WECHT                                      DECIDED: JULY 21, 2020
    Does the Commonwealth have a burden to establish harmless error? Unless the
    Majority is inclined to overrule our seminal decision on the harmless error doctrine, the
    answer incontrovertibly is “yes.” Commonwealth v. Story, 
    383 A.2d 155
    , 162 n.11 (Pa.
    1978) (“[T]he burden of establishing that the error was harmless beyond a reasonable
    doubt rests with the Commonwealth.”). Why, then, may a court raise the issue of
    harmless error sua sponte, and then proceed to rule in the Commonwealth’s favor
    thereon, despite the Commonwealth’s failure to carry its burden, and despite any attempt
    by the Commonwealth to raise, assert, cite, discuss, or apply the harmless error doctrine
    to the facts of the case? The Majority appears to suggest that it has resolved this second
    question today, but its answer is irreconcilable with the settled answer to the first question.
    A burden must be satisfied by the litigant who bears it, not by the adjudicator. Otherwise,
    it is no burden at all.
    The essential meaning of a “burden” in the law is readily understood by judges,
    lawyers, law students, scholars, television commentators, and laypersons alike. It means
    that there is some kind of obligation to carry one’s point, lest the point be lost. This might
    make the question before us appear to have an obvious answer.                 Not so.    The
    jurisprudential waters have significantly muddied over the last two decades. The crux of
    today’s appeal is the “tension” that has grown within our harmless error jurisprudence, a
    tension that manifests itself in two divergent lines of precedent. On the one hand, there
    is the fundamental principle, recognized by the Supreme Court of the United States in
    Chapman v. California, 
    386 U.S. 18
    (1967), and by nearly every court that has followed,
    that it is the prosecution’s burden to establish the harmlessness of an error that potentially
    tainted a defendant’s conviction.       See
    id. at 24;
    Story, 383 A.2d at 162 
    n.11;
    Commonwealth v. Davis, 
    305 A.2d 715
    , 719 (Pa. 1973).1 On the other hand, there is this
    1       State courts overwhelmingly recognize this burden. The cases are legion. See,
    e.g., State v. James, 
    443 P.3d 1063
    , 1079 (Kan. 2019) (“The burden of demonstrating
    harmlessness is on the party benefiting from the error, which, in this case, is the State.”);
    Coleman v. Binion, 
    829 S.E.2d 1
    , 26 (W.Va. 2019) (“In a criminal case, the burden is upon
    the beneficiary of a constitutional error to prove beyond a reasonable doubt that the error
    complained of did not contribute to the verdict obtained.”) (citation and internal quotation
    marks omitted); State v. Larkin, 
    183 A.3d 589
    , 595 (Vt. 2018) (“The State bears the
    burden of proving that an error . . . is harmless.”); State v. Rivas, 
    398 P.3d 299
    , 313-14
    (N.M. 2017) (“For a non-structural, constitutional error as has been established here, the
    State bears the burden of proving beyond a reasonable doubt that the error was harmless
    to the outcome.”); State v. DeLeon, 
    374 P.3d 95
    , 100 (Wa. 2016) (“The State bears the
    burden of showing that the constitutional error was harmless.”); State v. Perry, 
    245 P.3d 961
    , 973 (Idaho 2010) (constitutional error necessitates reversal “unless the State proves
    beyond a reasonable doubt that the error complained of did not contribute to the verdict
    obtained”) (citation and internal quotation marks omitted); State v. Sayles, 
    49 S.W.3d 275
    ,
    280 (Tenn. 2001) (“Once a constitutional error has been established . . . the burden is
    upon the State to prove that the constitutional right violation is harmless beyond a
    reasonable doubt.”) (citation and internal quotation marks omitted); Dawson v. State, 
    608 A.2d 1201
    , 1204 (Del. 1992) (“The defendant has the initial burden of demonstrating error.
    If the defendant is successful in discharging that obligation, the burden of proof shifts to
    the State.”).
    [J-93-2019] [MO: Saylor, C.J.] - 2
    Court’s more recent suggestion that an appellate court’s sua sponte invocation of the
    harmless error doctrine is a permissible exercise of the court’s prerogative to apply the
    right-for-any-reason doctrine—a notion floated in an undeveloped footnote in
    Commonwealth v. Mitchell, 
    839 A.2d 202
    , 215 n.11 (Pa. 2003), and applied by this Court
    on a handful of occasions since.
    Where our precedents hold simultaneously that there is a burden placed upon a
    party and that the court may elect at will to shoulder that burden itself, the precedents are
    incompatible. I would preserve the foundations of the harmless error doctrine, adhere to
    Story, and disavow our Mitchell line of cases. I would enforce the burden recognized in
    Chapman.
    Every United States Court of Appeals that adjudicates criminal cases also has
    come to the same conclusion. See, e.g., United States v. Rivera-Carrasquillo, 
    933 F.3d 33
    , 47 (1st Cir. 2019) (“The government bears the burden of proving harmlessness.”);
    United States v. Groysman, 
    766 F.3d 147
    , 155 (2d Cir. 2014) (“With respect to harmless-
    error analysis, the government bears the burden of proof.”); United States v. Franz, 
    772 F.3d 134
    , 151 (3d Cir. 2014) (“The government bears the burden of establishing
    harmlessness.”); United States v. Garcia-Lagunas, 
    835 F.3d 479
    , 488 (4th Cir. 2016)
    (“The burden rests on the government, the beneficiary of the error, to show
    harmlessness.”); United States v. Gutierrez-Mendez, 
    752 F.3d 418
    , 426 (5th Cir. 2014)
    (“The government has the burden of establishing harmlessness beyond a reasonable
    doubt.”); United States v. Susany, 
    893 F.3d 364
    , 368 (6th Cir. 2018) (“The government
    bears the burden of proof on harmless error . . . .”); United States v. Robinson, 
    724 F.3d 878
    , 888 (7th Cir. 2013) (“The burden of demonstrating harmlessness rests with the
    government.”); United States v. Davis, 
    859 F.3d 592
    , 597 (8th Cir. 2017) (“The
    government bears the burden of proving an error is harmless.”); United States v. Esparza,
    
    791 F.3d 1067
    , 1074 (9th Cir. 2015) (“The government bears the burden of proving that
    the error was harmless beyond a reasonable doubt.”); United States v. Russian, 
    848 F.3d 1239
    , 1248 (10th Cir. 2017) (“The government bears the burden of making this
    [harmlessness] showing.”); Bester v. Warden, 
    836 F.3d 1331
    , 1338 (11th Cir. 2016) (“The
    government, not the defendant, bears the burden of establishing that a constitutional error
    is harmless.”); United States v. Burnett,

    marks omitted).

    The Majority chooses a different path, opting to provide no standard at all.
    Ultimately, the Majority holds that a court may assume the Commonwealth’s burden “in
    appropriate cases.” Maj. Op. at 9. The court may conduct a harmless error analysis on
    its own initiative, the Majority reasons, pursuant to its “discretionary prerogative.”
    Id. at 10.
      Both the Majority and the Concurrence suggest some understanding that our
    appellate courts are expected to glean from today’s decision, pursuant to which jurists will
    recognize their sua sponte invocation of harmless error to be an “exception to the ordinary
    rule,”
    id. at 9,
    one that must be used with caution in response to the “extremely occasional
    need,” Conc. Op. at 2 (Donohue, J.), to do the Commonwealth’s job for it. I too am
    concerned by the “superficiality” with which harmless error analyses are commonly
    conducted. Maj. Op. at 12. But I find no practical limitations here, no standard, no rubric
    by which to distinguish an “appropriate” case from an inappropriate one, and no reason
    to expect that this purported “exception” to a litigant’s burden will prove to be anything
    other than the norm, to the extent that the exception has not swallowed the rule already.
    There is a straightforward path toward mitigating many of the problems that
    Appellant Hamlett has brought to our attention—a path grounded in the foundational case
    law from which we have departed. We should preserve the burden, in a form that is
    recognizable as such.
    The Majority does not discuss much of the jurisprudence underlying this inquiry.
    The Majority does not discuss the facts or history of this case, nor the intermediate court’s
    application of the law to the facts. See infra Part IV. Aside from a footnote providing
    citations to the decisions of this Court that Hamlett specifically challenges, Maj. Op. at 4
    n.3, the Majority does not meaningfully confront the precedents at issue. The harmless
    error doctrine has a long history; the approach that this Court embraces today is of a more
    [J-93-2019] [MO: Saylor, C.J.] - 4
    recent vintage.   In order to frame the question presented,2 to appreciate Hamlett’s
    criticisms of the approach that the Court embraces today, and to articulate the grounds
    for my profound disagreement with the Majority, it is necessary to set forth some
    background. It is imperative to understand the competing interests at play, to review the
    guiding principles of the doctrines at issue, and to consider where our jurisprudence has
    brought us and where it will go from here.
    I.
    Harmless error often is treated as a routine matter in the law, but we must remain
    cognizant of the stakes of the inquiry before us. To the individual appellant whose case
    is under review, the importance of the inquiry is immense—a harmless error analysis
    often represents the line between an accused’s entitlement to relief and the failure of his
    appeal. A finding of harmlessness deals a knockout blow, simultaneously acknowledging
    the merit in the appellant’s assertion of legal error while nonetheless informing the
    2     The Majority does not quote the question presented. We granted allowance of
    appeal on the following question, which we rephrased for clarity:
    Can the tension between the well-settled rule that the Commonwealth bears
    the burden of demonstrating harmless error beyond a reasonable doubt and
    the contradictory principle that an appellate court has the ability to affirm a
    valid judgment or verdict for any reason appearing as of record be
    reconciled? If these conflicting principles must be reconciled in favor of the
    Commonwealth proving harmlessness beyond a reasonable doubt, did the
    Superior Court err in finding harmless error sua sponte?
    Commonwealth v. Hamlett, 
    202 A.3d 45
    (Pa. 2019) (per curiam).
    The Majority states that, due to Hamlett’s framing of the appeal, “the issue does
    not encompass the narrower question of whether the Superior Court may have erred in
    the substantive aspects of its harmless-error review.” Maj. Op. at 3 n.2. However,
    because this Court rephrased the question presented, this conclusion is somewhat
    suspect. Because it is emblematic of certain problems in our jurisprudence, and because
    the Majority holds that such analyses may be conducted sua sponte in any event, I believe
    that the Superior Court’s present application of the harmless error doctrine warrants at
    least brief comment. See infra Part IV.
    [J-93-2019] [MO: Saylor, C.J.] - 5
    appellant that no remedy for that error will be forthcoming. And beyond the individual
    case lie important institutional concerns. In Story, we cautioned that “there is the danger
    that a lenient harmless error rule may denigrate the interests and policies which both
    constitutional and non-constitutional rules promote.” 
    Story, 383 A.2d at 164
    . We further
    admonished that “courts must be careful in applying the harmless error rule, for if the
    violation of a rule is too readily held harmless, the importance and effectiveness of the
    rule is denigrated.”
    Id. This unpleasant
    side effect not only can dilute and defeat
    important rights, but also can undermine the deterrence value of appellate reversal,
    demonstrating to future parties and courts that similar errors are inconsequential, and that
    scrupulous care need not be taken to avoid them.3 A rule that frequently is broken without
    consequence soon becomes no rule at all.
    There is, of course, another side to this coin. It would be unreasonable to demand
    perfection throughout the entire course of a criminal prosecution and trial. For that
    reason, it is a longstanding tenet of our law that, “although an accused is entitled to a fair
    trial, he is not entitled to a perfect one.” 
    Story, 383 A.2d at 164
    . Modern harmless error
    doctrine developed in the early twentieth century as a response to a “widespread and
    deep conviction” that appellate review of criminal cases had grown too demanding, and
    that appellate courts had become “‘impregnable citadels of technicality’” that often
    reversed hard-won convictions on the basis of trivial irregularities. Kotteakos v. United
    States, 
    328 U.S. 750
    , 759 (1946) (quoting Marcus A. Kavanagh, Improvement of
    3      See Hon. Harry T. Edwards, To Err Is Human, But Not Always Harmless: When
    Should Legal Error Be Tolerated?, 70 N.Y.U. L. REV. 1167, 1170 (1996) (hereinafter
    “Edwards”) (“When we hold errors harmless, the rights of individuals, both constitutional
    and otherwise, go unenforced. Moreover, the deterrent force of a reversal remains unfelt
    by those who caused the error. In his seminal book on harmless error, entitled The Riddle
    of Harmless Error, the late Justice Roger Traynor aptly observed that ‘[i]n the long run
    there would be a closer guard against error at the trial, if appellate courts were alert to
    reverse, in case of doubt, for error that could have contaminated the judgment.’”) (quoting
    ROGER J. TRAYNOR, THE RIDDLE OF HARMLESS ERROR 23 (1970)) (footnotes omitted).
    [J-93-2019] [MO: Saylor, C.J.] - 6
    Administration of Criminal Justice by Exercise of Judicial Power, 11 A.B.A.J. 217, 222
    (1925)). Undoubtedly, it is inefficient to order the repetition of an entire trial because of
    an immaterial error that could not possibly have affected the outcome.            Thus, the
    “harmless error rule can save the time, effort and expense of unnecessary retrials where
    the defendant has not been prejudiced by an error.” 
    Story, 383 A.2d at 164
    . But because
    the individual and institutional stakes are high, a balance must be struck: the rule must
    aim to “save the good in harmless-error practices while avoiding the bad, so far as
    possible.” 
    Chapman, 386 U.S. at 23
    .
    Both the Supreme Court of the United States and this Court historically struck that
    balance by constraining the harmless error doctrine with two fundamental rules. First,
    before an error may be deemed harmless, “the court must be able to declare a belief that
    it was harmless beyond a reasonable doubt.” 
    Davis, 305 A.2d at 719
    (quoting 
    Chapman, 386 U.S. at 24
    ).      “The second general precept” is that “the burden is on the
    Commonwealth to establish that the error was harmless.”
    Id. at 719;
    see 
    Chapman, 386 U.S. at 24
    ; 
    Story, 383 A.2d at 162
    n.11. The beyond-a-reasonable-doubt standard is
    commensurate with the prosecution’s burden at trial, and it would make little sense for an
    appellate court to apply a lesser standard to the harmlessness inquiry. 
    Story, 383 A.2d at 162
    . Moreover, this Court has explained, the beyond-a-reasonable-doubt standard
    reflects the prudent belief that “it is far worse to conclude incorrectly that the error was
    harmless than it is to conclude incorrectly that the error was reversible.” 
    Davis, 305 A.2d at 719
    .
    It is the “second general precept” of harmless error jurisprudence that is on the
    chopping block today. 
    Davis, 305 A.2d at 719
    . Fundamentally, the purpose of assigning
    the burden to the prosecution is to minimize the potential for unfairness to the appellant,
    for it is the prosecution that benefits from the finding of harmlessness. The Supreme
    [J-93-2019] [MO: Saylor, C.J.] - 7
    Court of the United States has explained that trial error “casts on someone other than the
    person prejudiced by it a burden to show that it was harmless.” 
    Chapman, 386 U.S. at 24
    . “It is for that reason that the original common-law harmless-error rule put the burden
    on the beneficiary of the error either to prove that there was no injury or to suffer a reversal
    of his erroneously obtained judgment.”
    Id. Although there
    are additional practical
    challenges in the application of the doctrine, these two essential safeguards—the
    governing standard and the assignment of the burden—maintain the relative balance in
    the competing interests that underlie harmless error, and restrain the doctrine from
    embracing too much of “the bad” about which Chapman warned us.
    In the past two decades, however, this Court began to distort this balance, tipping
    the scales in favor of the prosecution. In Mitchell, a capital direct appeal, this Court
    agreed with the appellant that the trial court had erred in permitting the prosecutor to
    impeach the appellant’s testimony at trial by reference to his exercise of his right to remain
    silent. The Court proceeded to a harmlessness inquiry. In a footnote that ultimately would
    engender the so-called “tension” in our jurisprudence that we confront today, this Court
    stated:
    Inexplicably, in this case the Commonwealth offers no alternative argument
    that the error was harmless, as it simply argues that no error occurred. We
    remind the Commonwealth that the burden of establishing harmless error
    rests squarely upon its shoulders. 
    Story, 383 A.2d at 162
    n.11. Despite
    this lapse by the Commonwealth, we are not without advocacy on this issue
    as the question of harmless error was directly raised and addressed by
    Appellant. Jurisprudentially, we can affirm the action of the court below on
    other grounds. Bearoff v. Bearoff Bros., Inc., 
    327 A.2d 72
    , 76 (Pa. 1974).
    
    Mitchell, 839 A.2d at 215
    n.11(citation modified).
    Although the Mitchell footnote is brief, there is much to unpack in it. It is evident
    that sua sponte invocation of harmless error was not commonplace at the time, as
    demonstrated by this Court’s scolding of the Commonwealth for its “lapse” in failing to
    [J-93-2019] [MO: Saylor, C.J.] - 8
    carry its burden—an oversight that this Court found “inexplicable.” Nonetheless, with a
    touch of judicial sleight of hand, this Court escaped the suggestion that it had raised the
    issue sua sponte at all, capitalizing upon the appellant’s foresight to have argued that the
    error was not harmless, and proceeding then to deem that sufficient “advocacy” to decide
    the issue. In one sentence, this Court flipped the longstanding burden on its head. The
    Commonwealth wholly failed to address, let alone meet, its burden; the appellant not only
    met his own burden to prove error, but went above and beyond to preempt the
    harmlessness argument that the appellant anticipated but which the Commonwealth itself
    never advanced.     As a reward for his diligence, this Court held that the appellant
    effectively had satisfied his opponent’s burden. It appears that the appellant would have
    been better served by less punctilious advocacy. Finally, without any reasoned analysis
    or discussion, this Court cited a single civil case referring to the right-for-any-reason
    doctrine, ostensibly as a justification for its decision to engage in harmless error analysis
    despite the Commonwealth’s failure to litigate the matter at all. This Court did not
    acknowledge that its approach facially conflicts with the universal understanding of a
    “burden” in the law as an obligation upon a party to prove the claim, or else to suffer
    defeat.
    Mitchell and its progeny embody the dangers of bad precedent. As sometimes
    happens, what began as merely an underdeveloped excuse for an unsound decision soon
    became the norm. In Commonwealth v. Moore, 
    937 A.2d 1062
    (Pa. 2007), this Court
    again confronted an error as to which the Commonwealth had failed to advance a
    harmlessness argument. Citing Mitchell, this Court again paid lip service to the waning
    premise that the burden to prove harmless error falls upon the Commonwealth. Yet, the
    Court again invoked the right-for-any-reason doctrine as a basis to overlook the
    Commonwealth’s omission. See
    id. at 10
    73. 
    Mitchell had metastasized into a line of
    [J-93-2019] [MO: Saylor, C.J.] - 9
    precedent, binding upon this Court and all below, despite its patent but unacknowledged
    conflict with Story, Davis, Chapman, and the foundational tenets of harmless error
    doctrine. By the time this Court decided Commonwealth v. Allshouse, 
    36 A.3d 163
    (Pa.
    2012), Mitchell’s approach was so engrained that the Court started simply citing the right-
    for-any-reason doctrine as a justification for sua sponte consideration of harmless error
    without even referring to the Commonwealth’s burden as such. See
    id. at 182
    (“It is well
    settled that an appellate court has the ability to affirm a valid judgment or verdict for any
    reason appearing as of record . . . . This Court may affirm a judgment based on harmless
    error even if such an argument is not raised by the parties.”) (citation and internal
    quotation marks omitted).
    This Court’s treatment of harmless error grew increasingly casual.                  In
    Commonwealth v. Hitcho, 
    123 A.3d 731
    (Pa. 2015), another capital direct appeal, this
    Court not only ignored the existence of a burden on the question of harmlessness, but,
    unlike earlier cases in this line, glossed over the fact that the Commonwealth had not
    advanced a harmlessness argument.4         After spending over a decade with the Mitchell
    footnote, it was no longer “inexplicable” that the Commonwealth had failed to carry its
    burden; the prosecution now could count on this Court to do the job for it. In Hitcho, this
    Court further abbreviated the analysis. The Court not only performed a harmlessness
    assessment on the Commonwealth’s behalf, it also declined even to consider a claim of
    error. This Court held that “we need not resolve the issue of whether the trial court abused
    its discretion in denying Appellant’s motion in limine . . . . Assuming, arguendo, the trial
    4       The Commonwealth’s brief in Hitcho made a single, passing reference to harmless
    error in the context of one discrete claim, but did not develop an argument on the matter,
    and did not refer to the “overwhelming evidence” standard that we would deem dispositive
    of a wholly different claim of error. Brief for Commonwealth, Commonwealth v. Hitcho,
    691 CAP, at 29 (“Even if [Pa.R.E. 106] was applicable, which it is not, the error would be
    harmless error.”). The analysis that I discuss was undertaken by this Court sua sponte.
    [J-93-2019] [MO: Saylor, C.J.] - 10
    court erred, given the overwhelming evidence establishing first-degree murder, we find
    any error to be harmless, and thus not warranting relief.” 
    Hitcho, 123 A.3d at 748
    . Putting
    the proverbial cart before the horse, the Court found harmlessness without finding error.5
    Absent any advocacy from the parties on the question, and instead forging ahead
    sua sponte, this Court then disregarded that the “overwhelming evidence” variety of
    harmless error necessitates that the evidence be uncontradicted—a requirement that
    prevents the reviewing court from making questionable assessments of the credibility of
    competing evidence from its inherently limited appellate perspective.6 As Story stated:
    The requirement that the “overwhelming” evidence relied upon be
    uncontradicted follows from the principle that an error cannot be harmless
    if “‘honest, fair minded jurors might very well have brought in not guilty
    verdicts.’” 
    Davis, 305 A.2d at 721
    (quoting 
    Chapman, 386 U.S. at 18
    ). A
    jury has the duty to weigh the evidence and resolve conflicts therein. E.g.,
    Commonwealth v. Murray, 
    334 A.2d 255
    (Pa. 1975). Unless the evidence
    5        We took a similar approach in 
    Allshouse, 36 A.3d at 182
    . Although we are not the
    first court to conduct such an analysis, and certainly will not be the last, this practice also
    raises self-evident doctrinal concerns. See 
    Edwards, supra
    n.3, at 1182 (“Another
    troubling aspect of this trend is judicial use of the harmless-error rule to avoid reaching a
    difficult issue in a case. Courts sometimes openly decline to decide whether a
    defendant’s rights have been violated, instead evading the issue by stating that any error
    that might have occurred was harmless. This practice leaves unresolved the question of
    whether an error even occurred, thus offering no guidance to trial courts. What may be
    an important question of trial error is therefore sidestepped by the application of a doctrine
    that itself presupposes the existence of such an error. Nothing suggests that the
    harmless-error rule was meant to serve such a purpose.”).
    6     For ease of reference, this Court traditionally recognizes three varieties of
    harmless error, which we have gleaned from our seminal discussion in Story:
    Harmless error exists if the reviewing court is convinced from the record that
    (1) the error did not prejudice the defendant or the prejudice was de minimis,
    (2) the erroneously admitted evidence was merely cumulative of other
    untainted evidence, or (3) the properly admitted and uncontradicted
    evidence of guilt was so overwhelming and the prejudicial effect of the error
    was so insignificant by comparison that the error could not have contributed
    to the guilty verdict.
    Commonwealth v. Petroll, 
    738 A.2d 993
    , 1005 (Pa. 1999) (emphasis added).
    [J-93-2019] [MO: Saylor, C.J.] - 11
    is uncontradicted a fair minded juror may well choose to credit the
    defendant’s, rather than the Commonwealth’s evidence.
    The principle is in accord with the proper function of an appellate court. An
    appellate court is ill equipped to resolve conflicts in the evidence or make
    findings of fact.
    
    Story, 383 A.2d at 167-68
    (citations modified).        Although the Hitcho Court quoted
    precedent that identified the correct standard, it nonetheless ignored this important
    element, and instead expressly rested its “overwhelming evidence” assessment, in part,
    upon an appellate credibility finding. The Court concluded that the defendant’s testimony,
    which “offered an explanation for his actions to the jury” and, thus, ostensibly contradicted
    at least portions of the Commonwealth’s evidence or the inferences derived therefrom,
    was “fraught with inconsistencies and based on an unbelievable version of events.”
    
    Hitcho, 123 A.3d at 748
    . In other words, this Court deemed a (potential) error harmless,
    sua sponte, based at least in part upon its own post hoc assessment of the defendant’s
    credibility, which the Court somehow gleaned on appeal from a cold record.             Such
    disregard for established standards sets a poor example for our courts, and does not
    inspire confidence in the soundness of this line of precedent.
    The Mitchell line of cases never overruled our landmark decision in Story, never
    disapproved of its progeny, and never disputed the longstanding and well-settled principle
    that the burden to prove harmlessness rests with the prosecution. 
    See supra
    at 2 & n.1.
    The cases also never recognized the contradiction—they merely cited the right-for-any-
    reason doctrine, then proceeded sua sponte as though the tension were resolved. But
    the tension remains. I addressed it directly in dissent in Commonwealth v. Hicks, 
    156 A.3d 1114
    , 1158 n.1 (Pa. 2017) (Wecht, J., dissenting), and the Superior Court in this
    case quoted my concerns before proceeding sua sponte to address harmlessness. See
    Maj. Op. at 2; Commonwealth v. Hamlett, 1172 WDA 2016, slip op. at 28 n.8, 2018 WL
    [J-93-2019] [MO: Saylor, C.J.] - 12
    4327391, at *13 n.8 (Pa. Super. Sept. 11, 2018).7 Hamlett identified the need for this
    Court to confront the matter, brought us this important appeal, and has directly framed
    this significant problem in our law with a challenge to the conflicting precedent. And so,
    here we are.
    II.
    The Majority does not concern itself with the soundness of the Mitchell line of
    cases, see Maj. Op. at 4 n.3, nor does it address the interests of the accused that are
    implicated by harmless error review. Although it rejects various of Hamlett’s arguments,
    in a manner that I address seriatim below, the Majority articulates one central conclusion
    to explain why sua sponte review for harmless error is permissible, notwithstanding the
    Commonwealth’s failure to make any attempt to carry its burden of persuasion: “[t]he
    harmless-error doctrine functions as the underlying substantive principle of law, and the
    right-for-any-reason precept merely provides the explanation for when and why an
    appellate court may exercise its discretionary prerogative to proceed of its own accord to
    preserve a valid verdict in appropriate circumstances.” Maj. Op. at 9.
    This is not a satisfactory answer. Whether the verdict to be preserved is “valid” is
    precisely the question that a harmless error analysis seeks to answer, and the answer
    7      Although my dissent in Hicks expressed skepticism about this facet of our
    harmless error jurisprudence, I felt bound there to “adhere to our precedential declaration”
    that sua sponte invocation of harmless error is permissible under the Mitchell line of
    cases. 
    Hicks, 156 A.3d at 1158
    n.1 (Wecht, J., dissenting) (citing 
    Allshouse, 36 A.3d at 182
    ). Upon review of the authorities and Hamlett’s focused, well-developed advocacy, I
    am compelled now to take a more exacting view. We should disavow the flawed
    precedent that generated the present controversy.
    As the Majority notes, Justice Baer’s concurrence in Hicks also recognized our
    precedential conflict, but resolved it in favor of sua sponte invocation of harmless error
    via the right-for-any-reason doctrine. Maj. Op. at 3; 
    Hicks, 156 A.3d at 1140
    (Baer, J.,
    concurring). Because this rationale is duplicative of that of the Mitchell line of cases, and
    reflects the same reasoning that the Majority adopts today, I will not separately address
    Justice Baer’s comments in Hicks.
    [J-93-2019] [MO: Saylor, C.J.] - 13
    cannot be known before the inquiry is conducted. Sua sponte application of the doctrine
    disregards a crucial component of the “underlying substantive principle of law.” It is the
    prosecution’s burden to establish harmless error. The court undertaking the analysis sua
    sponte is not so much applying the substantive principle as it is applying part of that
    principle, and dismissing the inconsistent part. The Majority characterizes the challenged
    practice as a straightforward, sua sponte application of the right-for-any-reason doctrine,
    but it is more accurately characterized elsewhere by the Majority as an “exception” to the
    “ordinary rule,”
    id., that the
    Commonwealth bears a burden on the question of whether a
    given error was harmless, or instead whether legal error, once identified, warrants relief.
    With no discernible standard to constrain the exception, I fail to understand what is left of
    the “ordinary rule.”
    Additionally absent from the Majority’s analysis is any recognition of the oft-
    repeated reasons that sua sponte decision-making is roundly disfavored in the law. Even
    setting aside the express burden applicable in the harmless error context, it is axiomatic
    that “[s]ua sponte consideration of issues deprives counsel of the opportunity to brief and
    argue the issues and the court of the benefit of counsel’s advocacy.”           Wiegand v.
    Wiegand, 
    337 A.2d 256
    , 257 (Pa. 1975). Raising and addressing issues sua sponte
    “disturbs the process of orderly judicial decision-making by depriving the court of the
    benefit of counsel's advocacy, and depriving the litigants the opportunity to brief and
    argue the issues.” Johnson v. Lansdale Borough, 
    146 A.3d 696
    , 709 (Pa. 2016) (citations
    omitted). But beyond mere prudential challenges, and of particular relevance given
    Hamlett’s specific argument to this Court, sua sponte decision-making may implicate due
    process concerns, to the extent that it deprives litigants of notice and an opportunity to be
    heard on potentially dispositive matters. See infra Part II(D). Before delving further into
    broader concerns, however, I turn next to the Majority’s various rationales for rejecting
    [J-93-2019] [MO: Saylor, C.J.] - 14
    several of Hamlett’s specific arguments, and the reasons for my disagreements with these
    rationales.
    A.     Judicial Economy
    The Majority first invokes principles of judicial economy, noting the “systemic
    interest in avoiding costly and unnecessary proceedings before the judiciary” and the
    “social costs of retrial, including those of the judicial system at large, jurors, victims, other
    witnesses, and the general public.” Maj. Op. at 10. Due to these interests, the Majority
    asserts, “[j]udicious recourse to the discretionary prerogative to review for harmless error
    may appropriately proceed” sua sponte, when the court deems it appropriate.
    Id. First, the
    Majority’s justification begs the question inasmuch as it relies upon the
    interest in avoiding “unnecessary” retrials, which again is precisely the question that a
    harmless error analysis seeks to answer. Through the harmless error doctrine, the parties
    litigate, and the court decides, whether it is a “valid verdict,”
    id. at 9,
    that the prosecution
    seeks to preserve despite an error, such that a retrial becomes “unnecessary.”
    Id. at 10.
    The answer to the question is meant to be provided through the parties’ advocacy—the
    Commonwealth’s, specifically—not through judicial intuition.
    Moreover, the Majority refers only to interests that underlie the harmless error
    doctrine generally, but which have little relation to the question of the Commonwealth’s
    burden. As it concerns the question before us, the typical framing of the interest in judicial
    economy is largely beside the point. It is no secret that the harmless error doctrine, at
    bottom, is informed significantly by principles of judicial economy. But that interest is in
    no way incompatible with the Commonwealth’s advocacy.                   Indeed, requiring the
    Commonwealth to carry its burden advances judicial economy in many ways, while sua
    sponte consideration of harmless error directly and palpably disserves the interest in
    judicial economy. Precisely because it is a highly record-intensive inquiry, harmless error
    [J-93-2019] [MO: Saylor, C.J.] - 15
    analysis is a labor. If it is to be conducted with due rigor, the burden to establish the claim
    must fall somewhere. As I explain below, in allowing the Commonwealth’s burden to be
    relieved in the appellate court’s discretion, the Majority spares none of the resources of
    our trial courts, but allows a heavy workload to fall upon our already-busy appellate courts.
    Setting aside precedent, fairness, important underlying interests, and institutional
    concerns, perhaps it is helpful to discuss the reasons that the Commonwealth is better
    suited than the appellate court to advocate for harmless error, as a purely practical matter.
    Although appellate courts regularly review evidentiary records, we necessarily maintain a
    relatively detached relationship with them. When we first open the papers filed in a given
    appeal, we have no prior knowledge of the case. We were not in the courtroom at trial,
    nor have we observed any witness’ demeanor, nor have we seen the parties’ pre-trial or
    post-trial motions, nor have we heard their objections or offers of proof. We and the
    record simply are not acquainted. We rely heavily upon the lower courts’ summaries of
    the facts and proceedings, and to a lesser extent the parties’ representations, in order to
    orient ourselves to the legal questions presented for review. Naturally, those questions
    generally require us to consult the record, but we tailor our review to the issues before
    us, and we require that the parties provide us with citations to the portions of the record
    that contain the pertinent material. See, e.g., Pa.R.A.P. 2119(c) (“If reference is made to
    the pleadings, evidence, charge, opinion or order, or any other matter appearing in the
    record, the argument must set forth, in immediate connection therewith, or in a footnote
    thereto, a reference to the place in the record where the matter referred to appears”). We
    require such citation precisely because it is both onerous and inefficient for an appellate
    court to embark upon a self-guided tour through an unfamiliar fact record.8
    8        Cf. United States v. Hasting, 
    461 U.S. 499
    , 516-17 (1983) (Stevens, J., concurring
    in the judgment) (“This Court is far too busy to be spending countless hours reviewing
    trial transcripts in an effort to determine the likelihood that an error may have affected a
    [J-93-2019] [MO: Saylor, C.J.] - 16
    Unlike the appellate court, the parties are intimately familiar with the fact record.
    They built it. They know how its pieces fit together. The parties were in the courtroom.
    They filed the motions. They presented the evidence and questioned the witnesses.
    They argued the case to the fact-finder. They studied the materials in preparation for
    appeal. It is they who have command of the record, and it is they who can direct the
    reviewing court to the portions thereof that support or undercut their respective positions.
    Accordingly, it is the Commonwealth, not an appellate court reviewing a cold record
    months, years, or even decades later, that is in the best position to establish the
    harmlessness of an error. The Commonwealth is well-equipped to identify and draw the
    court’s attention to, for instance, the remainder of the uncontradicted evidence asserted
    to be overwhelming, or the properly introduced evidence of which the erroneous evidence
    was merely cumulative. 
    See supra
    n.6.
    In the absence of any argument from the Commonwealth, the appellate court is
    left in unfamiliar terrain without a guide. In order to render its judgment with any degree
    of confidence, the court seeking to establish harmless error on its own initiative must
    commence an exacting, systematic, and laborious review of the record with no direction
    from the parties. This is plainly a burdensome exercise for any appellate court. See, e.g.,
    United States v. Giovannetti, 
    928 F.2d 225
    , 226 (7th Cir. 1991) (per curiam) (noting that
    sua sponte consideration of harmless error “would place a heavy burden on the reviewing
    court, deprived as it would be of the guidance of the parties on the question whether
    particular errors were harmless”). This is not a revolutionary observation.
    jury’s deliberations. . . . I have spent several hours reviewing the one copy of the trial
    transcript that has been filed with the Court. But I have not read all of its 1,013 pages,
    and I have read only a few of the 450 pages of the transcript of the suppression hearing.
    The task of organizing and digesting the testimony is a formidable one.”).
    [J-93-2019] [MO: Saylor, C.J.] - 17
    Certainly, in both the right-for-any-reason and harmless error contexts, the interest
    in judicial economy often refers to the avoidance of unnecessary retrials—surely a
    considerable burden upon our trial courts. See Maj. Op. at 10. But, from the trial court’s
    perspective, it does not matter at all whether it is the Commonwealth or the appellate
    court that makes the harmlessness showing. If an error is to be deemed harmless, the
    end result—affirmance—is the same, and the resources of the trial court are spared to
    precisely the same degree regardless of whether the Commonwealth satisfies its burden
    or the appellate court shoulders that burden itself. The difference is that, where the
    parties litigate the matter and guide the court through the fact record, the analysis can be
    completed much more quickly, efficiently, and with greater confidence in the outcome. By
    contrast, where the Commonwealth fails to carry its burden, and the appellate court
    undertakes a self-directed harmless error analysis, the court must enmire itself in the
    record, parse it for any and all potentially relevant details, and thereby expend a significant
    amount of the court’s time and resources, at the expense of other cases on its docket.
    There can be no serious argument that it is not at least preferable for the
    Commonwealth to provide the reviewing court with meaningful advocacy on a potentially
    challenging, highly record-intensive inquiry such as harmless error. It is for this reason
    that the crux of Hamlett’s argument regarding judicial economy is that, although “the
    practice of sua sponte review for harmless error might hypothetically advance judicial
    economy in the trial courts, it does so at the expense of judicial economy in the appellate
    courts.” Brief for Hamlett at 38. This is plainly true, but with one caveat. Condoning the
    practice of sua sponte review advances judicial economy in the trial court only if we
    assume that the Commonwealth, if required, would regularly fail to perform its duty as an
    advocate, and that it somehow becomes the appellate court’s role to do the
    Commonwealth’s job as an alternative to the consequence that should rightly follow from
    [J-93-2019] [MO: Saylor, C.J.] - 18
    the Commonwealth’s dereliction. The procedure by which a judgment is affirmed on
    appeal is of no particular concern to the trial court.
    The Majority’s focus upon judicial economy extends only to the harmless error
    doctrine’s standard, general admonitions relating to the costs of retrial. None of that is
    inconsistent with the placement of a burden upon the Commonwealth, nor with requiring
    the Commonwealth to carry that burden. The Majority criticizes a number of Hamlett’s
    arguments as “impugning harmless-error review as such, as distinguished from the sua
    sponte aspect.” Maj. Op. at 11 n.9. Yet, a number of the Majority’s “primary lines of
    attack,”
    id., also rely
    upon principles applicable to harmless error review as such, as
    distinguished from the sua sponte aspect.           Avoidance of the “societal costs” of
    unnecessary retrials is wholly compatible with the Commonwealth advocating for its
    position. The sua sponte component of this jurisprudence has never concerned itself with
    the fact that the appellate court is doing the actual work of conducting self-guided
    harmless error analyses, which speaks volumes about the law’s concern for judicial
    economy. By contrast, if the Commonwealth advocates for its position, every step of the
    appellate process becomes more efficient.
    The most reasonable solution to these problems, from a judicial economy
    perspective, is that the Commonwealth must be made to carry its burden. If we begin to
    enforce the burden, the Commonwealth will learn to carry it again.          It was once
    “inexplicable” for the Commonwealth to so fail. 
    Mitchell, 839 A.2d at 215
    n.11. Opting
    instead to find harmlessness sua sponte changes nothing in the trial courts, but shifts a
    heavy workload onto our busy appellate courts. It saves no precious judicial resources.
    It expends them.      The entire exercise spares the effort of one party alone—the
    Commonwealth.       Sua sponte harmless error review is not judicial economy.        It is
    prosecutorial economy.
    [J-93-2019] [MO: Saylor, C.J.] - 19
    B.     Right-For-Any-Reason
    I would prefer not to dwell at great length upon the right-for-any-reason doctrine,
    nor upon its conflation with the harmless error doctrine, because I think it plain that the
    two doctrines are indeed distinct, that they have distinct purposes, and that there is a
    reason that they were given distinct names in the first place. I also believe that the sua
    sponte practice that the Majority approves is not actually an application of the right-for-
    any-reason doctrine, but rather that it is simply an attempt to apply harmless error
    principles on the court’s own initiative, with the Commonwealth’s burden conspicuously
    absent from the analysis. But the ostensible connection between these doctrines is the
    jurisprudential anchor of the Majority’s approach, so it is worth considering the ways in
    which harmless error and the right-for-any-reason doctrine converge and diverge.
    To separate the right-for-any-reason doctrine from harmless error, Hamlett
    proposes a taxonomy to this Court, suggesting that trial error be classified as either error
    of “admission,” “use,” or “rationale.” Brief for Hamlett at 17-23. He argues that only errors
    in rationale are amenable to disposition under the right-for-any-reason doctrine, because,
    in such a circumstance, the admission or use of the evidence was not erroneous; the only
    deficiency was the trial court’s reason for a correct action. But if the admission or use of
    the evidence had no valid justification at all, then it is truly erroneous, and the error may
    find no safe harbor under the right-for-any-reason doctrine.
    The Majority rejects Hamlett’s framework, opining that “the selection of an incorrect
    basis for admitting evidence can be viewed as employment of an erroneous rationale,”
    and, thus, that Hamlett’s categories are “not mutually exclusive.”         Maj. Op. at 11.
    Rejecting Hamlett’s lexicon, however, does not result inexorably in a functional
    equivalence between the harmless error and right-for-any-reason doctrines. I find that
    Hamlett’s classification scheme presents a useful exercise, but it merely places a label
    [J-93-2019] [MO: Saylor, C.J.] - 20
    upon elementary right-for-any-reason principles. It is not necessary to the analysis,
    because differences between the doctrines abound.
    Of course, an immediate and dispositive distinction is that the harmless error
    doctrine always has imposed a burden upon the prosecution, while the right-for-any-
    reason doctrine places no parallel burden upon the party seeking its benefit. But that is
    not even the most obvious difference. As evidenced by their very names, the doctrines
    pose different questions to the court. When an appellate court applies the right-for-any-
    reason doctrine, it ultimately finds no reversible error, because the challenged decision
    was “right,” for a different reason than was articulated below. The right-for-any-reason
    doctrine asks the question: “Was the challenged action erroneous?” Harmless error, by
    contrast, is a question of effect—once an error has been found, harmless error doctrine
    asks the question: “Did the error change the outcome?”
    The right-for-any-reason doctrine is best conceptualized as allowing for the
    identification of an alternative, valid, legal justification for a challenged action. “We have
    often stated that where a court makes a correct ruling, order, decision, judgment or
    decree, but assigns an erroneous reason for its action, an appellate court will affirm the
    action of the court below and assign the proper reason therefor.” 
    Bearoff, 327 A.2d at 76
    (emphasis added; capitalization modified). It is self-evident that an “error” is not a
    “correct ruling” suitable for disposition under the right-for-any-reason doctrine. Rather,
    an error is an error, suitable for analysis under the harmless error doctrine.
    An archetypal example of the right-for-any-reason precept occurs when the trial
    court offers a flawed rationale for its decision to admit a challenged piece of evidence, but
    the facts nonetheless support the admission of that evidence for a different reason or
    pursuant to a different rule. To perform the right-for-any-reason analysis in such a case,
    the appellate court merely must assess whether the established evidence of record
    [J-93-2019] [MO: Saylor, C.J.] - 21
    satisfies an existing legal rule—a familiar task for appellate courts. If the facts fit the rule,
    then we may conclude that the challenged action was proper, not erroneous. See, e.g.,
    In re A.J.R.-H., 
    188 A.3d 1157
    , 1176 (Pa. 2018) (“The [right-for-any-reason] doctrine thus
    may be applied by a reviewing court if the established facts support a legal conclusion
    producing the same outcome.”). If such is an error, it is an error only in form, not in
    substance. See Thomas v. Mann, 
    28 Pa. 520
    , 522 (Pa. 1857) (“The only error upon the
    record is a wrong reason for a right judgment; but, as we review not reasons but
    judgments, we find nothing here to correct.”). With harmless error, by contrast, there is
    something to correct. There is a legal error that may have impacted the outcome.
    The right-for-any-reason doctrine does not require the appellate court to consider
    the effect of an error on the totality of the proceedings. The analysis does not require a
    speculative inquiry into the likely impact upon a juror of hearing erroneously admitted
    evidence, or an examination of whether the evidence may have strengthened certain
    arguments in the eyes of a juror or called others into question, or—ultimately—a
    determination that the jury still would have returned a guilty verdict absent the evidence.
    These latter inquiries are hallmarks of the challenges underlying harmless error. Where
    the right-for-any-reason doctrine is concerned with legal justifications, harmless error is
    essentially more of a factual judgment than a legal one—whether, under the facts and
    circumstances presented, beyond a reasonable doubt, a jury would have returned the
    same verdict regardless of the error.
    Answering the harmlessness question, moreover, poses intractable difficulties
    stemming from the inherent limitations of appellate review. Quoting California Chief
    Justice Roger Traynor’s famous treatise on harmless error, this Court in Story observed:
    The appellate court is limited to the mute record made below. Many factors
    may affect the probative value of testimony, such as age . . . intelligence,
    experience, occupation, demeanor, or temperament of the witness. A trial
    court or jury before whom witnesses appear is at least in a position to take
    [J-93-2019] [MO: Saylor, C.J.] - 22
    note of such factors. An appellate court has no way of doing so. It cannot
    know whether a witness answered some questions forthrightly but evaded
    others. It may find an answer convincing and truthful in written form that
    may have sounded unreliable at the time it was given. A wellphrased
    sentence in the record may have seemed rehearsed at trial. A clumsy
    sentence in the record may not convey the ring of truth that attended it when
    the witness groped his way to its articulation. What clues are there in cold
    print to indicate where the truth lies? What clues are there to indicate where
    the half-truth lies?
    
    Story, 383 A.2d at 168
    (quoting ROGER J. TRAYNOR, THE RIDDLE OF HARMLESS ERROR 20-
    21 (1970)).
    This Court has developed certain guidelines in order to make our journey into these
    unfamiliar waters more comfortable—such as requiring that harmlessness be predicated
    upon uncontradicted evidence so as to avoid the morass of appellate credibility
    determinations. See 
    Story, 383 A.2d at 166-68
    . This Court also has overlooked those
    guidelines in our sua sponte pursuit of the doctrine. See 
    Hitcho, 123 A.3d at 748
    . The
    truth of the matter is that harmless error analysis remains a challenging task in a
    significant number of cases. The endeavor is unavoidably speculative. The doctrine asks
    appellate judges to evaluate and assess the persuasiveness of the entirety of an
    evidentiary record, to run a hypothetical trial in our minds sanitized of the legal error before
    us, while setting aside our own suspicions as to the guilt or innocence of the accused
    (which may indeed be influenced by the error at issue), and to opine conclusively as to
    how a hypothetical jury would have viewed a hypothetical body of evidence. 9 This is
    9      Although such analyses pose unique difficulties on appeal, it would be an
    overstatement, of course, to suggest that appellate courts are wholly incapable of
    rendering judgments about the potential impact of certain evidence upon the fact-finder,
    or the ultimate likelihood that a different result would have obtained. Indeed, in modern
    post-Chapman jurisprudence, harmless-error-type inquiries have been engrafted upon a
    number of substantive legal rules, such as the standard for demonstrating prejudice in
    the ineffectiveness of counsel context, and the test for materiality under Brady v.
    Maryland, 
    373 U.S. 83
    (1963). See 
    Edwards, supra
    n.3, at 1178 (conceptualizing the
    development of these standards as an outgrowth of the harmless error rule). For better
    [J-93-2019] [MO: Saylor, C.J.] - 23
    palpably dissimilar from many of the purely legal considerations that might be resolved
    easily and fairly under the right-for-any-reason doctrine.        Fortunately, although the
    harmlessness inquiry can be challenging, the court need not go it alone. The court can
    be aided greatly by the parties’ advocacy, 
    see supra
    Part II(A), and, in particular, by an
    effort from the Commonwealth, as the beneficiary of the error, to demonstrate that the
    error could not have contributed to the verdict.
    The Majority may dismiss Hamlett, or me, as “impugning harmless-error review as
    such, as distinguished from the sua sponte aspect.” Maj. Op. at 11 n.9. But by these
    observations, I mean to reveal disparities between the doctrines before us, to the extent
    that those disparities tend to undercut the Majority’s thinly supported assertion that one
    doctrine may be viewed as a mere application of the other.10 Given the specific challenge
    or worse, this has become a familiar exercise. A critical difference in the Brady and
    ineffectiveness areas, however, is that the burden to make the showing is placed upon
    the appellant instead of the prosecution, and this Court, at least, strictly requires the
    appellant to carry that burden, and will not hesitate to deem the appellant’s claim waived
    if it lacks sufficient development. I further address concerns regarding issue-preservation,
    development, and waiver below. See infra at 25-27; 38-40.
    10      Although it favorably cites a Georgia decision, the Majority acknowledges that its
    approach—collapsing the harmless error rule into the right-for-any-reason doctrine and
    approving limitless sua sponte invocation of either—is not common among American
    jurisdictions. Maj. Op. at 9 n.6. The Majority deems all other approaches to sua sponte
    consideration of harmless error to be simply a “close cousin” of its own approach, but it
    does not elaborate upon this assertion. I question the degree of relation.
    For its recourse to Georgia law, the Majority invokes Jones v. State, 
    802 S.E.2d 234
    , 237 (Ga. 2017) (admission of prior bad acts evidence “was harmless as to
    appellant’s conviction and sentence . . . and so the Court of Appeals’ judgment is affirmed
    as right for any reason”); see Maj. Op. at 9. However, the same tension that the Mitchell
    footnote has engendered in Pennsylvania appears to afflict Georgia’s jurisprudence in
    precisely the same way. The Jones Court did not refer to the harmless error rule as
    imposing a “burden” at all, despite the Georgia Supreme Court’s recognition of that
    burden with respect to evidentiary errors like that found in Jones, even in cases decided
    in the same year as Jones. See Bozzie v. State, 
    808 S.E.2d 671
    , 677 (Ga. 2017) (“For
    nonconstitutional harmless error, the State has the burden to show that it was highly
    probable that the error did not contribute to the verdict.”). Although the Majority
    [J-93-2019] [MO: Saylor, C.J.] - 24
    before this Court—which reveals significant difficulties with the sua sponte aspect of the
    challenged jurisprudence on multiple fronts, and which suggests a simple solution—the
    remainder of one’s opinions about the balance of the harmless error rule would seem to
    be of little consequence.
    Perhaps some additional insight into the Majority’s reasoning may be gleaned from
    its summary of the Commonwealth’s arguments, inasmuch as the Majority “agree[s] with
    the Commonwealth in all material respects.” Maj. Op. at 8. Accordingly, one may
    presume that the Majority endorses at least all of the Commonwealth’s arguments that it
    summarizes in its Opinion. Concerning the absence of the Commonwealth’s burden
    when the court pursues harmless error sua sponte under the right-for-any-reason
    doctrine, the Majority favorably quotes the Commonwealth’s reliance upon a “core
    precept underlying the right-for-any-reason doctrine, which is that only appellants are
    charged with issue preservation obligations, whereas appellees bear none.”
    Id. (citing Brief
    for Commonwealth at 42) (emphasis in original). Hamlett’s position, the Majority
    and the Commonwealth fret, might “upend this conventional approach to issue
    preservation by imposing waiver, or its functional equivalent, on the government as
    appellee.”
    Id. (citing Brief
    for Commonwealth at 7, 42).
    First of all, it is curious that the Majority would deem “issue preservation
    obligations” to be a “core precept” of the right-for-any-reason doctrine, for it apparently
    does not view the prosecution’s burden of persuasion to be a “core precept” of the
    harmless error doctrine. The prosecution’s burden is indeed a “core precept” of harmless
    error; in fact, it is the “second general precept” underlying the doctrine. 
    Davis, 305 A.2d at 719
    ; 
    see supra
    at 7; see 
    also supra
    n.1. When harmless error “functions as the
    establishes that we are not alone in rendering incompatible pronouncements on harmless
    error, nothing in Jones helps to reconcile the incongruity between unfettered sua sponte
    review and the recognition of a burden imposed upon a party.
    [J-93-2019] [MO: Saylor, C.J.] - 25
    underlying substantive principle of law,” Maj. Op. at 9, to which the court resorts through
    its discretionary prerogative to employ the “right-for-any-reason precept,”
    id., what happens
    to the general precepts of the harmless error doctrine? It seems that a core
    precept of the harmless error doctrine is jettisoned, yet what the Commonwealth simply
    insists is a “core precept” of the right-for-any-reason doctrine mysteriously remains.
    In any event, the Commonwealth’s focus upon the absence of an issue-
    preservation obligation upon appellees is a non sequitur.         Maj. Op. at 8; Brief for
    Commonwealth at 42, 46. We have never suggested that the Commonwealth’s burden
    is one of issue-preservation; the Commonwealth need not raise the issue before the trial
    court in the first instance on pain of waiver. Its burden is one of persuasion, and may be
    satisfied by offering argument to the reviewing court for the first time on appeal. The
    absence of an issue-preservation burden upon appellees, thus, is irrelevant. The point
    would be roughly equivalent to suggesting that a court may research, litigate, and rule
    upon a claim that the appellant fails to assert in its brief, simply because the appellant
    preserved an objection and included the issue in its Pa.R.A.P. 1925(b) statement. Issue-
    preservation is beside the point.
    We speak of a burden of persuasion. Even if one assumes that it would be absurd
    or unreasonable to impose an issue-preservation burden upon the Commonwealth as to
    the harmlessness question, the suggestion of the Commonwealth’s “waiver” would not
    follow from failure to preserve an issue. A finding of waiver is not a ludicrous response
    to an observation that a litigant has failed to develop advocacy on a question as to which
    it bears the burden. Even guiding federal jurisprudence, to which the Majority adverts but
    does not discuss, recognizes the government’s failure to advocate as precisely this sort
    of “waiver.” 
    Giovannetti, 928 F.2d at 226
    ; see infra at 38-40; but see Maj. Op. at 10 n.7.
    The point that the Majority appears not to appreciate is that we will enforce an appellant’s
    [J-93-2019] [MO: Saylor, C.J.] - 26
    “waiver” for failure to develop a claim upon which the appellant bears the burden of
    persuasion, but we are appreciably hesitant to impose any consequence whatsoever
    upon the Commonwealth’s identical failure, or even to acknowledge it as such. We have
    hesitated so long that a “tension” with fundamental principles has arisen in our
    jurisprudence, which we now have been asked to confront and to resolve.
    Commonwealth v. Hamlett, 
    202 A.3d 45
    (Pa. 2019) (per curiam).
    After its diversion into issue-preservation concerns, the Majority next favorably
    quotes a set of excuses that the Commonwealth provides as to why it is onerous for it to
    carry its burden of persuasion—a point that strikes me less as concerning the right-for-
    any-reason doctrine and more as an argument in favor of overruling Story, but I digress.
    The Majority summarizes the Commonwealth’s assertion that “there are many reasons
    why advocates representing appellees may refrain from presenting certain alternative
    arguments, such as out of a concern that such references might dilute the strength of
    primary contentions, or on account of word-count limitations on briefing.”
    Id. (citing Brief
    for Commonwealth at 43, 50). The Commonwealth, and by extension the Majority, seems
    to question whether our courts are capable of effectively weighing a legal argument that
    is followed by an alternative analysis. I am not so skeptical of our appellate jurists’
    abilities. Able lawyers themselves, I am confident that they can identify and recognize
    the purpose of an alternative argument. There is no reason to believe that courts will
    suddenly begin to overlook meritorious legal arguments because the Commonwealth also
    argues, in the alternative, that the asserted error was harmless. As for word-count
    limitations, we do not allow such requirements to serve as an excuse for any other litigant
    to fail to advocate for his or her position, and they manage to do so even in highly complex
    cases. And, of course, if the Commonwealth fears that presenting arguments to the court
    will cause it to expend the 14,000 words allotted to it, it remains free to seek the court’s
    [J-93-2019] [MO: Saylor, C.J.] - 27
    leave for an exception.11 I am further certain that our procedural rules could respond to
    any systemic concerns that such advocacy may present.            Pointing to word-count
    limitations is little more persuasive than would be an assertion that we must have due
    regard for circumstances in which the Commonwealth’s dog eats its homework.
    The right-for-any-reason and harmless error doctrines may ultimately serve similar
    ends—affirmance—but they are not the same doctrine. In the Majority’s conflation of
    them, the obligation of the Commonwealth to advocate for its position has gone missing.
    The Majority asserts that what it describes is an invocation of the “right-for-any-reason
    precept” to apply the harmless error doctrine as the “underlying substantive principle of
    law,” Maj. Op. at 9, but I fail to understand why the “second general precept” of the
    harmless error doctrine, 
    Davis, 305 A.2d at 719
    , simply disappears from the analysis.
    Because core precepts of these doctrines stand in clear tension with one another,
    perhaps the analysis is not as straightforward as the Majority suggests.
    C.     Judicial Impartiality
    Hamlett further contends that sua sponte harmlessness findings are in tension with
    the fundamental obligation of the judiciary to remain neutral and impartial. He reminds
    us that the adversarial process, essential to the American model of criminal justice, has
    two central components:     “(1) neutral and passive decision makers and (2) party
    presentation of evidence and arguments.” Brief for Hamlett at 38 (quoting Adam A. Milani
    & Michael R. Smith, Playing God: A Critical Look at Sua Sponte Decisions by Appellate
    Courts, 69 TENN. L. REV. 245, 272 (2002)). Hamlett argues that the practice of raising
    and deciding issues sua sponte, harmless error in particular, stands in tension with the
    well-understood role of appellate courts, articulately described by then-Judge Antonin
    11     Pa.R.A.P. 2135(a)(1) (“Unless otherwise ordered by an appellate court . . . a
    principal brief shall not exceed 14,000 words . . . .”).
    [J-93-2019] [MO: Saylor, C.J.] - 28
    Scalia as bodies that “do not sit as self-directed boards of legal inquiry and research, but
    essentially as arbiters of legal questions presented and argued by the parties before
    them.”
    Id. (quoting Carducci
    v. Regan, 
    714 F.2d 171
    , 177 (D.C. Cir. 1983)).12 “Put
    simply,” Hamlett summarizes, “where the Commonwealth fails to take an adversarial
    position on the matter of harmless error, it is not up to the appellate courts to pick up the
    slack.”
    Id. at 40.
      The now-prevailing approach, Hamlett observes, “confers upon
    reviewing courts essentially unfettered discretion” in deciding whether to reverse or to
    pursue harmless error.
    Id. at 42.
    This, in turn, “imperils our jurisprudential ideals of
    evenhandedness, predictability, consistency in the development of legal principles,
    reliability on judicial decisions, and the actual and perceived integrity of the judicial
    process.”
    Id. at 41.
    The Majority rejects Hamlett’s argument without substantial discussion, adverting
    again to principles of judicial economy and the “larger concerns” of the “social costs of
    retrial.” Maj. Op. at 10. I believe that those latter interests are largely the responsibility
    of the Commonwealth to advance, if it so desires. I also find the perceived neutrality of
    the judiciary to be an exceptionally weighty concern. Hamlett’s observations ring true in
    many respects. Although there are other issues that a court may raise sua sponte
    pursuant to longstanding precedent, I can conjure no other circumstance where a party
    has an express and established burden to prove a particular assertion, yet the court may
    excuse that burden, take it upon itself, and declare victory for the party who has done
    nothing to claim it. Earlier in this opinion, I characterized the finding of harmlessness as
    a “knockout blow,” inasmuch as it adversely disposes of the appellant’s claim of error.
    12    See also McNeil v. Wisconsin, 501 U.S. 171,181 n.2 (1991) (“What makes a
    system adversarial rather than inquisitorial is . . . the presence of a judge who does not
    (as an inquisitor does) conduct the factual and legal investigation himself, but instead
    decides on the basis of facts and arguments pro and con adduced by the parties.”).
    [J-93-2019] [MO: Saylor, C.J.] - 29
    Supra at 5. But when the court finds harmlessness without being asked or without the
    matter being litigated, that final punch comes not from one of the boxers; it is thrown by
    the referee. The appellant has proven the existence of an error—the Commonwealth is
    on the ropes. Yet, in comes the referee with the harmlessness haymaker, and the
    appellant is down for the count. Certainly, no one watching that bout would characterize
    the referee as a passive and neutral arbiter.
    At the very least, the continued absence of guidance from this Court as to when
    the harmlessness question may or should be raised sua sponte—a problem that persists
    through today’s decision—allows for inconsistent application and potentially arbitrary
    results. As it stands now, different panels of our Superior Court may take wholly different
    approaches. One panel finding an error may observe that the words “harmless error”
    appear nowhere in the Commonwealth’s brief, and simply reverse. Another panel may
    take that same appeal and same error, and proceed to a harmlessness inquiry sua
    sponte. Further, without guidance or argument from the parties, panels undertaking the
    inquiry sua sponte may emphasize different aspects of the case, or find something in the
    record that others might overlook on their self-guided tour, leading panels to reach very
    different conclusions on the question.     The fault for inconsistency in the case law,
    however, lies not with the Superior Court. The Commonwealth is not to blame either,
    even though the routine absence of its advocacy is the source of many of the identified
    ills. The fault lies with this Court, which gradually has eroded the Commonwealth’s
    burden, but has left our lower courts without guidelines for sua sponte application of the
    doctrine.
    Concern for evenhandedness would appear to be particularly acute in this context,
    inasmuch as a finding of harmlessness always redounds to the benefit of the prosecution,
    never to the defense. Perhaps this is why a portion of the Commonwealth’s argument
    [J-93-2019] [MO: Saylor, C.J.] - 30
    endorsed by the Majority can glibly suggest that, “[s]urely, the appellate courts of this
    Commonwealth do not take lightly their duty to make fair and just decisions when the lives
    and liberty of criminal defendants are at stake.”         Maj. Op. at 8 (quoting Brief for
    Commonwealth at 27). Naturally the Commonwealth is not particularly concerned; it
    stands to lose very little from deficient findings of harmless error. I believe that Hamlett
    has identified, and I have discussed, cases in which even this Court has given questions
    of harmless error less than the full consideration that they may have deserved. The fact
    that the Commonwealth can provide a list of cases that it deems to contain “good” uses
    of sua sponte harmless error review,
    id. (citing Brief
    for Commonwealth at 27 n.2), does
    not remove the potential for arbitrariness and abuse that inheres in the practice. It is
    facially suspect that a court is empowered to intervene on behalf of, and to assume the
    role of an advocate for, one party but not the other. This may be regarded as a question
    of appearance, regardless of whether the resolution of any particular case is driven by
    unseemly motivations. Cf. In Interest of McFall, 
    617 A.2d 707
    , 711 (Pa. 1992) (“We hold
    herein that the impartiality of the court, which is a fundamental prerequisite of a fair trial,
    must be deemed compromised by appearance alone, thus eliminating the need for
    establishing actual prejudice.”). A truly impartial arbiter requires each party to carry its
    own burden.
    D.     Due Process
    The Majority rejects Hamlett’s due process argument in one paragraph, with two
    indirect responses. Hamlett develops an intriguing claim. He begins with the most
    fundamental command of due process: “that deprivation of life, liberty or property by
    adjudication be preceded by notice and opportunity for hearing appropriate to the nature
    of the case.” Brief for Hamlett at 30 (quoting Mullane v. Cent. Hanover Bank & Trust Co.,
    
    339 U.S. 306
    , 313 (1950)). The critical right to be heard “has little reality or worth unless
    [J-93-2019] [MO: Saylor, C.J.] - 31
    one is informed that the matter is pending and can choose for himself whether to appear
    or default, acquiesce or contest.”
    Id. at 31
    (quoting 
    Mullane, 339 U.S. at 314
    ). When an
    appellate court performs a harmless error analysis sua sponte, after the parties have filed
    their briefs, without informing them that the issue will be dispositive of the appeal, and
    without providing the appellant with an opportunity to argue against the finding, the
    appellate court deprives the appellant of due process. Moreover, such a circumstance
    deprives the appellant of the opportunity to be heard by counsel, in further tension with
    due process norms.
    Id. at 33-35.
    Hamlett reminds us that the “right to be heard would
    be, in many cases, of little avail if it did not comprehend the right to be heard by counsel.”
    Id. at 34
    (quoting Powell v. Alabama, 
    287 U.S. 45
    , 68-69 (1932)).
    Notably, unlike the United States Constitution, the Pennsylvania Constitution
    expressly guarantees the right to appeal.13        Accordingly, in this Commonwealth, a
    convicted defendant has an express right to appeal his judgment of sentence, and has a
    right to due process, which, at a minimum, contemplates notice and an opportunity to be
    heard before the disposition of a matter in which his life or liberty is at stake. At least in
    this context,14 merely combining a few fundamental propositions of law reveals that
    Hamlett’s suggestion is compelling.
    13     See PA. CONST. art. V, § 9 (“There shall be a right of appeal in all cases to a court
    of record from a court not of record; and there shall also be a right of appeal from a court
    of record or from an administrative agency to a court of record or to an appellate court,
    the selection of such court to be as provided by law; and there shall be such other rights
    of appeal as may be provided by law.”).
    14     The suggestion that sua sponte decision-making may raise due process concerns
    is not unheard of in Pennsylvania law, nor in broader legal scholarship. See Fallaro v.
    Yeager, 
    528 A.2d 222
    , 224 (Pa. Super. 1987) (“Due process requires that the litigants
    receive notice of the issues before the court and an opportunity to present their case in
    relation to those issues. It is even more e[g]regious an error when the lack of notice,
    through variance from the pleadings, is the court’s doing. For when the issue is first stated
    only in the court’s resolution of it, the unsuspecting party has no opportunity during the
    proceedings to voice his objections or match his case to the altered issue.”) (quoting In
    [J-93-2019] [MO: Saylor, C.J.] - 32
    The Majority gives two reasons for rejecting Hamlett’s position, neither of which
    responds directly to Hamlett’s constitutional grievance. First, the Majority concludes that
    sua sponte consideration of harmless error does not deprive an appellant of due process
    because, if this were the case, then the federal statute and rule that provide for harmless
    error review would be “patently unconstitutional as applied to their authorization of
    harmless-error review by the federal appellate courts acting of their own accord.” Maj.
    Op. at 10-11. Although this is a worthy matter to ponder, it is ultimately beside the point,
    for the constitutionality of federal practice is not the question here, and, in any event, the
    right to appeal is not enshrined in the federal Constitution, as it is in ours. Supra n.13.
    Regardless, as the Majority seems to acknowledge, recognizing a due process
    component of the procedure by which harmlessness is determined would not necessarily
    render the federal enactments facially unconstitutional, inasmuch as the Majority refers
    to as-applied challenges. Perhaps unbounded discretion to resort to harmless error sua
    sponte is also problematic in federal court. See infra Part III. We are not called upon to
    so decide; it is Pennsylvania law that is before us today.          Because the Majority’s
    observation does not substantively respond to Hamlett’s contention regarding the
    contravention of due process norms, I am uncertain as to why it should dispose of
    anything here.
    The Majority provides one additional reason to dispense with Hamlett’s due
    process argument.      The Majority states: “In cases in which harmlessness may be a
    Interest of M.B., 
    514 A.2d 599
    , 601 (Pa. Super. 1986), aff’d, 
    538 A.2d 495
    (Pa. 1988));
    see generally Barry A. Miller, Sua Sponte Appellate Rulings: When Courts Deprive
    Litigants of an Opportunity to Be Heard, 
    39 S.D. L
    . REV. 1253 (2002).
    Hamlett’s invocation of due process also is echoed by the only amicus curiae
    participating in this appeal. See Brief for Amicus Curiae Pennsylvania Association of
    Criminal Defense Lawyers at 4-12 (arguing that sua sponte findings of harmless error
    deprive the appellant of the right to counsel and the due process right to notice and an
    opportunity to be heard).
    [J-93-2019] [MO: Saylor, C.J.] - 33
    factor . . . able defense attorneys can well anticipate that appellate courts may be
    legitimately concerned with the societal costs attending a new trial, and those attorneys
    are free to address the prejudicial impact of trial errors in their own appellate briefs.” Maj.
    Op. at 11. This point likewise fails to respond directly to Hamlett’s grievance, but it is also
    highly problematic for at least three additional reasons.
    First, this is nothing more than improper burden-shifting. The Majority seems to
    be giving standing instructions to defense attorneys that, if they wish to represent their
    clients “ably,” perhaps effectively, they had better argue against harmlessness as a matter
    of course, lest the Commonwealth fail to meet its burden and the appellate court choose
    to tag itself in. This strikes me as no different than inverting the Commonwealth’s burden
    and placing it upon defense counsel. The Majority cautions against the right-for-any-
    reason doctrine imposing a “high barrier to reversal,”
    id. at 11
    , 
    but it imposes ever more
    hurdles to relief. Where once the Commonwealth had a burden to establish harmless
    error, now the Majority expects “able” defense counsel to anticipate that the
    Commonwealth will fail to advocate for its position, and it instructs defense counsel, on
    counsel’s own initiative, to expend additional resources to rebut an argument that has not
    yet been made, as to which the Commonwealth nominally has the burden of persuasion
    and the defense accordingly should stand in a responsive posture, so as to persuade the
    court that the substantive legal error, which defense counsel will have just proven on the
    merits, is worthy of relief—all of this depending, of course, upon whether the court
    employs its discretion to consider harmless error at all. The Majority instructs defense
    attorneys not only to satisfy their own burdens to prove legal error, but also to rebut, in
    advance, the argument that the Commonwealth might or might not choose to make, and
    that the court might or might not choose to undertake. The Majority not only shuffles the
    responsibility for the doctrine over to defense counsel, it asks defense counsel to go first.
    [J-93-2019] [MO: Saylor, C.J.] - 34
    Without knowing what the Commonwealth would argue, or if it will argue, counsel filing
    the principal brief for the appellant can offer only speculative defenses to hypothetical
    arguments about harmless error.
    Is the Commonwealth not an “able” advocate for its own position?
    Second, the Majority’s comment on the duties of able defense counsel arises in
    the context of a due process claim regarding the deprivation of notice and an opportunity
    to be heard on a critical matter. To my knowledge, due process jurisprudence has never
    placed the onus upon the individual subject to the deprivation to anticipate such
    deprivation and launch a prophylactic challenge thereto. To the contrary, it is inherent in
    the concept of “notice” that the individual is to be provided with notice of adverse action;
    he is not expected to divine and preempt it. See, e.g., 
    Mullane, 339 U.S. at 314
    (“An
    elementary and fundamental requirement of due process in any proceeding which is to
    be accorded finality is notice reasonably calculated, under all the circumstances, to
    apprise interested parties of the pendency of the action and afford them an opportunity to
    present their objections.”) (emphasis added).
    Third, the Majority’s suggestion to able defense counsel overlooks our own
    precedent. In the Mitchell footnote, itself—the beginning of this line of cases that has
    usurped Story—this Court used an able defense attorney’s proactive advocacy as a
    substitute for the Commonwealth’s burden, and went so far as to suggest that our
    consideration of harmless error therefore was not even an action taken sua sponte. See
    
    Mitchell, 839 A.2d at 215
    n.11; supra at 8. We then overlooked the Commonwealth’s
    dereliction, and ruled against the appellant.     Today’s Majority does not suggest its
    disapproval of the Mitchell footnote, and indeed it directly embraces the legal approach
    that Mitchell pioneered, or clumsily engrafted upon our case law. Against the backdrop
    of the precedent challenged in the very case before us, the Majority’s suggestion that able
    [J-93-2019] [MO: Saylor, C.J.] - 35
    defense counsel should anticipate and argue against harmless error strikes me as a cruel
    sort of irony.
    The Majority speaks of what it deems to be the current state of Pennsylvania law,
    and lauds its “due and appropriate regard for defendants’ substantive rights.” Maj. Op. at
    6-7. I see due and appropriate regard in Story. I do not find it in the Mitchell footnote, or
    in Hitcho. I see a credible assertion of a substantive constitutional right in this case, which
    the Majority dodges with arguments that do not respond to the deprivation that both
    Hamlett and amicus have identified and placed squarely within this Court’s view. I do not
    doubt that the law on this question can reflect a better balance between “the promotion
    of judicial economy” and the “due and appropriate regard for defendants’ substantive
    rights.” Maj. Op. at 7. The law can require the Commonwealth to advocate for the
    Commonwealth’s position, can demand that the defense be given notice and an
    opportunity to respond, and can tell the court to simply adjudicate rather than attempt to
    play judge, prosecutor, and defense counsel all at once.
    Harmless error is often the line between a new trial and many years in prison.
    Where the stakes are such, it is only fair to provide the interested party with notice that
    the issue is under consideration, and with an opportunity to speak on the matter through
    counsel. Regardless of whether the deprivation of that notice and opportunity constitutes
    a due process violation, it certainly is less than a completely fair practice. The Majority
    seems to recognize as much, at least by implication. See Maj. Op. at 12 (suggesting that
    a court considering harmlessness sua sponte in “close cases” may order supplemental
    briefing in order to “enhance fairness to the defendant”). Every defendant should be
    entitled to fairness; fairness should not need to be “enhanced” in any particular case. The
    way to encourage evenhanded treatment is to set a consistent standard and then apply
    it rigorously. Due process or not, that is simply a matter of good judicial practice.
    [J-93-2019] [MO: Saylor, C.J.] - 36
    III.
    All participants here—the parties, the Majority, the Concurrence, and myself—
    have made some references to federal harmless error practice. Both the Majority and the
    Concurrence refer to the standard for sua sponte consideration of harmless error outlined
    in the Seventh Circuit’s oft-cited, per curiam decision in Giovannetti, 
    928 F.2d 225
    , though
    they do not discuss its details. See Maj. Op. at 12 n.10; Conc. Op. at 2 (Donohue, J.).
    Giovannetti also appears in the advocacy of the parties.            Accordingly, it is worth
    considering the legal analysis to which the parties, the Majority, and the Concurrence all
    refer, alongside a recognition of the ways in which Pennsylvania jurisprudence differs
    from its federal counterpart on matters of harmless error.
    Federal criminal law provides for harmless error analysis by statute and rule,
    neither of which have a corollary in Pennsylvania criminal law. Both the federal statute
    and rule direct a reviewing court, in mandatory language, to disregard any error that does
    not affect the “substantial rights” of a party. Brief for Hamlett at 26-27 & nn. 17-18 (quoting
    Fed.R.Crim.P. 52(a) (“Any error, defect, irregularity, or variance that does not affect
    substantial rights must be disregarded.”); 28 U.S.C. § 2111 (“On the hearing of any
    appeal . . . the court shall give judgment after an examination of the record without regard
    to errors or defects which do not affect the substantial rights of the parties.”)). Hamlett is
    quick to point out that Pennsylvania has no such statute, and although similar “substantial
    rights” provisions appear elsewhere in our procedural rules, there is no such language in
    our Rules of Criminal or Appellate Procedure.
    Id. at 28.
    Harmless error is judge-made
    law in Pennsylvania.
    Also noteworthy, in my view, is that the Supreme Court of the United States has
    described the harmless error inquiry under the Federal Rules of Criminal Procedure as
    the inverse of the appellant’s burden to prove plain error. See United States v. Olano,
    [J-93-2019] [MO: Saylor, C.J.] - 37
    
    507 U.S. 725
    , 734 (1993) (“When the defendant has made a timely objection to an error
    and Rule 52(a) [(harmless error)] applies, a court of appeals normally engages in a
    specific analysis of the district court record—a so-called ‘harmless error’ inquiry—to
    determine whether the error was prejudicial. Rule 52(b) [(plain error)] normally requires
    the same kind of inquiry, with one important difference: It is the defendant rather than the
    Government who bears the burden of persuasion with respect to prejudice.”). Unlike the
    federal judiciary, this Court does not recognize the plain error doctrine; rather, we strictly
    adhere to a paradigm of issue-preservation and waiver. See generally Pa.R.A.P. 302. In
    this way, federal jurisprudence reflects a symmetry wholly lacking in Pennsylvania law.
    Earlier I quoted the Seventh Circuit’s per curiam decision in Giovannetti for its
    observation that conducting a harmless error analysis sua sponte “would place a heavy
    burden on the reviewing court.” 
    Giovannetti, 928 F.2d at 226
    ; supra at 17. The court
    discussed this labor while rejecting the government’s primary argument:              that the
    government’s harmless error arguments, themselves, are “nonwaivable.”
    Id. at 226.
    The
    court rejected the government’s contention that the mandatory language of Fed.R.Crim.P.
    52(a)—errors which do “not affect substantial rights shall be disregarded”—meant “that
    even if the government does not argue harmless error, we must search the record—
    without any help from the parties—to determine that the errors we find are prejudicial,
    before we can reverse.”
    Id. The court
    was troubled by the burdens that would fall to the
    court instead of the government, and cautioned against the “salami tactics” that the
    government could use to hedge against having to argue the issue at all.
    Id. “Such tactics
    would be particularly questionable in a case such as this,” the court emphasized, “where
    the defendant goes out of his way to argue that the error of which he complains was
    prejudicial, and the government by not responding signals its acquiescence that if there
    was error, it indeed was prejudicial.”
    Id. But see
    Mitchell, 839 A.2d at 215 
    n.11.
    [J-93-2019] [MO: Saylor, C.J.] - 38
    This satisfied the Giovannetti court that “harmless-error arguments can be waived.”
    
    Giovannetti, 928 F.2d at 226
    .15 It was a “separate question” whether the government’s
    waiver “always binds the court.”
    Id. Thus, looking
    elsewhere in the federal rules, and
    finding a general rule of construction in favor of simplicity, fairness, and the elimination of
    unjustifiable expense, the Giovannetti court concluded that its powers were discretionary;
    that courts “are not required to scour a lengthy record on our own, with no guidance from
    the parties,” but that they may deem themselves “authorized, for the sake of protecting
    third-party interests including such systemic interests as the avoidance of unnecessary
    court delay, to disregard a harmless error even though through some regrettable
    oversight harmlessness is not argued to us.”
    Id. Despite its
    deep reservations about sua sponte use of the harmless error doctrine,
    and despite its refusal to excuse the government’s waiver in the very case before it, the
    Giovannetti court nonetheless developed a multifactorial test pursuant to which a court
    may “overlook” the government’s waiver and proceed sua sponte.
    Id. at 227.
    The
    “controlling considerations,” the court explained, are: (1) “the length and complexity of
    the record”; (2) “whether the harmlessness of the error or errors found is certain or
    debatable”; and (3) “whether a reversal will result in protracted, costly, and ultimately futile
    proceedings in the district court.”
    Id. Applying that
    standard, the Giovannetti court
    ultimately concluded that the case before it did not warrant sua sponte consideration of
    harmless error, and it accordingly “decline[d] to relieve the government from the
    consequences of its failure to raise the issue of harmless error in its brief on appeal.”
    Id. 15 But
    see Maj. Op. at 8 (agreeing with the “the Commonwealth’s view” that Hamlett
    “seeks a novel decisional rule that would necessarily upend this conventional approach
    to issue preservation by imposing waiver, or its functional equivalent, on the government
    as appellee”).
    [J-93-2019] [MO: Saylor, C.J.] - 39
    The federal intermediate courts widely have adopted some version of the
    Giovannetti test, but the Supreme Court has never endorsed its rubric. See, e.g., United
    States v. Gonzales-Flores, 
    418 F.3d 1093
    , 1099-1101 (9th Cir. 2005); United States v.
    Rose, 
    104 F.3d 1408
    , 1414-15 (1st Cir. 1997); United States v. Pryce, 
    938 F.2d 1343
    ,
    1347-48 (D.C. Cir. 1991) (plurality). I do not find the test persuasive. Even if all of its
    factors counsel in favor of sua sponte review, it nonetheless suffers from the same
    fundamental deficiency as the Majority’s analysis herein—it allows the court to excuse
    and then assume a litigant’s burden of persuasion. Furthermore, the Giovannetti test is
    not harmonious with our general approach to waiver in Pennsylvania. Although the
    Majority summarily states that Giovannetti’s discretionary approach “is also the case in
    the Pennsylvania state courts,” Maj. Op. at 10 n.7, we do not generally instruct our courts
    to “overlook” a party’s waiver. Pennsylvania law treats waiver most strictly. Moreover,
    there is a degree of internal tension within the Giovannetti test, inasmuch as avoiding a
    “protracted” and “costly” retrial would appear to cut in favor of sua sponte review, but such
    a retrial likely would be protracted and costly precisely because of the “length” and
    “complexity” of the record—a factor that Giovannetti suggests would militate against sua
    sponte review. Conversely, a short and simple record seemingly would suggest that sua
    sponte review is more manageable, but for precisely that reason, a retrial would be
    relatively less burdensome and costly, thus counseling against sua sponte review.
    Regardless, the third Giovannetti factor—avoidance of “costly” but “ultimately
    futile” retrials—is merely a reference to the concerns with judicial economy that undergird
    the whole doctrine, not a helpful or case-specific consideration. The Majority refers in
    passing to the second Giovannetti factor, which I take to be the essence of the test: that
    the court should be “certain” that the error is harmless, and should not conduct the inquiry
    if it is “debatable.” 
    Giovannetti, 928 F.2d at 227
    . It remains mysterious to me how one
    [J-93-2019] [MO: Saylor, C.J.] - 40
    could purport to be certain that an error was harmless in the course of “deciding whether
    to exercise [the court’s] discretion” to consider the doctrine sua sponte in the first place.
    Id. One seemingly
    must be certain of an error’s harmlessness before even considering
    the harmless error doctrine. The Majority suggests that the requirement of “certainty” is
    a “more discerning review” than the court might apply if it was not proceeding sua sponte.
    Maj. Op. at 12 n.10. I fail to see how elevating the standard to “certainty” is meaningfully
    different than applying the beyond-a-reasonable-doubt standard that ordinarily governs
    the inquiry. 
    See supra
    Part I. We will never be “certain” of what twelve jurors would have
    done if the trial had been different. The ordinary beyond-a-reasonable-doubt review is
    essentially as “discerning” a standard as the law can provide. To demand the court’s
    assertion of “certainty” means only that the court must utter a magic word before it
    proceeds to do precisely what it would have done otherwise.
    Contrary to what may be the tacit suggestion of either the Majority or the
    Concurrence, or both, the Giovannetti test is not fit for this inquiry. A notable feature of
    many decisions applying Giovannetti or inquiries like it in other jurisdictions is some
    measure of caution in the approach, and some recognition of the potential downsides of
    sua sponte review. See, e.g., 
    Gonzales-Flores, 418 F.3d at 1101
    (“[W]e are particularly
    sensitive to the . . . concerns that sua sponte consideration of harmlessness will often
    burden reviewing courts and give the government too many chances to argue harmless
    error.    Even more troubling, the practice may unfairly tilt the scales of justice by
    authorizing courts to construct the government’s best arguments for it without providing
    the defendant with a chance to respond. . . . We therefore conclude that sua sponte
    recognition of an error’s harmlessness is appropriate only where the harmlessness of the
    error is not reasonably debatable.”) (emphasis in original); People v. Sandoval, 
    363 P.3d 41
    , 78 (Cal. 2015) (“Courts in other jurisdictions have warned of ‘the dangers of allowing
    [J-93-2019] [MO: Saylor, C.J.] - 41
    sua sponte consideration of harmlessness,’ including ‘the potential burden on reviewing
    courts of searching the record without guidance from the parties and encouragement of
    sloppy practice by lawyers.’”) (quoting Gover v. Perry, 
    698 F.3d 295
    , 300 (6th Cir. 2012)).
    Indeed, in Story, this Court similarly urged care and circumspection in the application of
    harmless error analysis, albeit in response to a different set of concerns underlying the
    doctrine. See 
    Story, 383 A.2d at 164
    (“[C]ourts must be careful in applying the harmless
    error rule, for if the violation of a rule is too readily held harmless, the importance and
    effectiveness of the rule is denigrated.”).
    The Majority attempts to echo some of this caution, noting that many federal courts
    generally find sua sponte harmless error review to be “extraordinary” and that it “should
    be disfavored.” Maj. Op. at 12.16 The Majority urges that its approach “not be routinely
    or liberally employed to impose a high barrier to reversal of criminal convictions.”
    Id. at 11.
    However, the Majority sets no meaningful standard, and it proposes no guardrails to
    ameliorate the worst of the dangers of its holding. The Majority does not even attempt to
    set forth any specific considerations along the lines of the Giovannetti test, flawed though
    that test may be. The Majority seemingly has left us with among the most amorphous of
    rules in the nation, leading the Concurrence to note the Majority’s reference to
    Giovannetti, and to ponder a “question left unanswered” by the Majority. Conc. Op. at 2
    (Donohue, J.).    The question that the Concurrence believes the Majority has left
    unanswered is not an insignificant one: “What is the relevant test for determining whether
    an error affected the outcome when harmless error is invoked sua sponte?”
    Id. I wish
    to
    16    Given the Majority’s recognition of the comments of federal courts as a general
    admonition that the practice is extraordinary and should be disfavored, Maj. Op. at 12,
    the Majority’s observation that federal courts are not “necessarily required to invoke
    harmless-error precepts sua sponte,”
    id. at 10
    n.7, is something of an understatement.
    [J-93-2019] [MO: Saylor, C.J.] - 42
    know the answer to this question as well. Unlike the Concurrence, however, the absence
    of an answer to that question precludes me from supporting the Majority Opinion.
    IV.
    The Majority does not speak to the facts, and alludes only generally to the
    substance of the Superior Court’s sua sponte application of the harmless error doctrine
    in this case. 
    See supra
    n.2; Maj. Op. at 1-2, 3 n.2. Although the Majority considers the
    substance of the case before us to be outside the scope of the question presented, its
    approval of sua sponte review for harmless error suggests that we may consider the
    matter irrespective of the parties’ advocacy. I do not feel it improper, then, to exercise
    my discretion to consider the very finding of harmless error that precipitated the instant
    appeal. But we need not dwell on the matter, for only a small amount of additional detail
    reveals significant problems.
    The Majority relates that the Superior Court found error in the admission into
    evidence of a video-recorded forensic interview with the victim of the alleged sexual
    assault, but the Superior Court deemed the error harmless, sua sponte, because it found
    the video to be merely cumulative of properly-admitted evidence in the form of the victim’s
    testimony. Maj. Op. at 1-2. To reach that point, however, the Superior Court undertook
    a thorough analysis of Pa.R.E. 61317 and related case law, and it found error in the
    17    Rule 613 provides, in relevant part:
    (c) Witness’s Prior Consistent Statement to Rehabilitate. Evidence of
    a witness’s prior consistent statement is admissible to rehabilitate the
    witness’s credibility if the opposing party is given an opportunity to cross-
    examine the witness about the statement and the statement is offered to
    rebut an express or implied charge of:
    (1) fabrication, bias, improper influence or motive, or faulty memory and the
    statement was made before that which has been charged existed or arose;
    or
    [J-93-2019] [MO: Saylor, C.J.] - 43
    admission of the video because it contained a prior consistent statement offered merely
    for the impermissible purpose of corroboration, and not to rehabilitate the credibility of a
    witness who had been impeached. Hamlett, slip op. at 18-27, 
    2018 WL 4327391
    , at *8-
    12. But when the court turned to harmless error, sua sponte, it held that the error was
    harmless because the prior consistent statement was merely cumulative of the victim’s
    testimony—the very testimony that it improperly sought to corroborate.
    Id. at 27-30,
    2018
    WL 4327391
    , at *12-14. How can an error be dismissed as merely cumulative, and thus
    harmless, when its cumulative nature was the very reason that it was error? The Superior
    Court stated that the same testimony that rendered the admission of the video erroneous
    also simultaneously made the error of its admission harmless. Surely that cannot suffice
    to allow an appellate court to conclude, beyond a reasonable doubt, that the absence of
    the error—video corroboration of critical testimony—would not have influenced the jury’s
    assessment of the credibility of competing evidence.
    The court further noted that Hamlett testified in his own defense, and it did not
    purport to base its conclusion upon overwhelming and uncontradicted evidence of
    Hamlett’s guilt, but rather upon the “merely cumulative” variety of harmless error. Yet,
    the court saw fit to predict the manner in which the jury would have viewed the credibility
    of competing testimony, but for the error. Hamlett understandably asserted that the
    impermissible corroboration of the victim’s in-court testimony may have prejudiced him in
    the eyes of the jury, inasmuch as the video could tend to bolster the credibility of the
    victim’s in-court testimony. The Superior Court disagreed:
    (2) having made a prior inconsistent statement, which the witness has
    denied or explained, and the consistent statement supports the witness’s
    denial or explanation.
    Pa.R.E. 613(c).
    [J-93-2019] [MO: Saylor, C.J.] - 44
    The jur[ors] heard from [the victim] under oath and their fundamental task
    was to weigh the credibility of her story against that of [Hamlett], who
    testified in his own defense. While we agree that our evidentiary rules prefer
    to avoid prior consistent statements, as set forth at 
    length supra
    , we do not
    believe that the jury would be unduly swayed by the knowledge [the victim]
    previously related the same story. Indeed, the jury presumptively assumed
    that was the case. Thus, while there was no need to buttress her testimony,
    the recorded statement was merely cumulative and harmless beyond a
    reasonable doubt. [Hamlett] is therefore not entitled to a new trial despite
    the error.
    Hamlett, slip op. at 30, 
    2018 WL 4327391
    , at *14 (citation omitted).
    This was not a sufficient application of any of the harmless error standards
    discussed in Story. 
    See supra
    n.6. The analysis of the cumulative nature of the evidence
    was nonresponsive to the nature of the error, and the evidence that otherwise might have
    been deemed “overwhelming” was expressly contradicted.            It requires an appellate
    credibility determination to say that an error such as this was harmless. To do so, the
    appellate court must step into the juror box. The “superficiality” that the Majority rightly
    criticizes is present in the very case before us. Maj. Op. at 12. Here, the “right-for-any-
    reason doctrine” was indeed “routinely” and “liberally” employed to “impose a high barrier
    to reversal” of a criminal conviction.
    Id. at 11.
    Hamlett merely points to ills in our
    jurisprudence that appear plainly in the pages before us, which continue to echo the flaws
    in cases like Mitchell and Hitcho.
    Future courts and litigants will research this question, they will find our decision
    today, and they will rely upon it. Particularly given this Court’s admonition that “decisions
    are to be read against their facts,” Maloney v. Valley Med. Facilities, Inc., 
    984 A.2d 478
    ,
    489 (Pa. 2009),18 I can only presume that many of those courts and litigants will consult
    18      See also Tincher v. Omega Flex, Inc., 
    104 A.3d 328
    , 378 (Pa. 2014) (“This case
    speaks volumes to the necessity of reading legal rules—especially broad rules—against
    their facts and the corollary that judicial pronouncements should employ due modesty.”)
    (citing 
    Maloney, 984 A.2d at 489-90
    ).
    [J-93-2019] [MO: Saylor, C.J.] - 45
    the facts of this case and the lower court decision that we affirm, as they struggle to
    determine how to apply the law that the Majority expounds today. When they do, they
    will find a self-contradictory harmless error analysis, which weighs the credibility of
    contradicted evidence, which eschews the safeguards designed precisely to avoid the
    defects from which it suffers, and by which this Court apparently is not troubled. They will
    see this Court’s approval and perpetuation of an oxymoronic statement of the law: that
    the “harmless error doctrine places the burden on the Commonwealth to prove beyond a
    reasonable doubt that the error could not have contributed to the verdict,” but that
    simultaneously, “our jurisprudence does not require the Commonwealth to raise the
    matter” at all. Hamlett, slip op. at 27, 
    2018 WL 4327391
    , at *12. Litigants and courts alike
    now will offer pro forma quotations from today’s Majority Opinion in their briefs and
    opinions, stating that the Commonwealth’s burden to establish harmless error is the
    “ordinary rule,” Maj. Op. at 9, before moving immediately to the “exception,” i.e., the
    court’s unbounded discretion to ignore the ordinary rule in “appropriate” cases.
    Id. My impression
    would be that the Commonwealth’s burden is gone in all but name, and that
    this Court does not plan to police the use of the harmless error doctrine any longer.
    V.
    Our harmless error jurisprudence has gone astray because we have eroded one
    of its foundations. We have before us the opportunity to rein in the worst of its potential
    for misuse. The problems are apparent in our own precedent and in the very case before
    us. The Majority sees at least some of these problems, and it criticizes the “superficiality”
    with which harmlessness is commonly discerned. Maj. Op. at 12. But today the Majority
    declines the opportunity to do anything about it.
    Instead, the Majority places all of these weighty considerations within the sole
    discretion of the appellate court, but it offers no test, no set of factors, no interests to
    [J-93-2019] [MO: Saylor, C.J.] - 46
    balance. Indeed, the Majority’s analysis barely acknowledges that a burden exists, or
    existed, at all. Its substantive discussion mentions the Commonwealth’s burden once,
    which it characterizes as the “ordinary rule” to which discretionary sua sponte invocation
    of harmless error serves as an “exception” to be used “in appropriate cases.”
    Id. at 9.
    The Majority cautions the Commonwealth that it “proceeds at its own risk,”
    id. at 11
    n.8,
    when it declines to satisfy its burden, but the Majority does not meaningfully discuss the
    consequence that might befall the Commonwealth should the court choose not to come
    to its aid, nor does the Majority provide guidance as to when a court should decide that
    the Commonwealth’s “risk” should become a loss. As far as I can tell from the Majority’s
    holding, the appellate court may overlook the Commonwealth’s burden whenever it
    wants. That is not a “burden” upon a litigant to establish harmless error. It is a suggestion,
    at best; it is an invitation for arbitrariness in adjudication at worst. Our courts need and
    deserve more guidance.
    To that end, I reiterate that the most straightforward solution is simply to resuscitate
    and then enforce the Commonwealth’s burden of persuasion on appeal.                       The
    Commonwealth’s principal brief is the best place to carry its burden, thereby allowing the
    appellant to address the Commonwealth’s argument in a reply brief in the ordinary course.
    The Commonwealth is the best and most able advocate for its own position,
    particularly as it concerns a highly record-intensive inquiry such as harmless error. Our
    appellate courts are busy, and I see no compelling reason why the Commonwealth’s work
    should ever fall to the court, for that does not advance judicial economy. Thus, should
    the Commonwealth fail to advance a harmless error argument, or should it be expected
    to fail so regularly as to require us to place a safety valve in our jurisprudence, I view a
    focused briefing procedure to be the only possible solution that would achieve a more fair
    balance of harms, relative to the alternative of standardless exercises in sua sponte

    decision-making.19 Generally speaking, some type of briefing procedure tailored to the
    harmlessness question could: (1) preserve the Commonwealth’s burden of persuasion;
    (2) relieve the court of the weighty and ill-defined question of when it should take up the
    matter sua sponte, mitigating the potential for arbitrariness and abuse along with it; and
    (3) provide the appellant with notice and an opportunity to respond, thus going a long way
    toward resolving the problems identified in this appeal. Whatever our approach, however,
    it should be applied uniformly and consistently between cases, not in an ad hoc manner
    that depends upon whether the court deems it “appropriate” to “enhance fairness to the
    defendant” in a given case. Maj. Op. at 12.
    A supplemental briefing procedure also would have clear downsides, in that it
    would result in quite a bit of additional delay for appellants, who often are incarcerated
    and eagerly awaiting resolution of their appeals. A significant increase in the volume of
    briefs filed also surely would place an additional administrative burden upon our
    prothonotaries. Accordingly, the Commonwealth’s principal brief remains the best place
    for the argument, and the court should not have to invite the Commonwealth to carry its
    burden. To the extent that our courts lack the will to enforce the Commonwealth’s burden
    with the threat of reversal, however, I would not exclude the possibility that certain
    deficiencies in our practice perhaps could be mitigated by a nuanced and informed
    rulemaking process. The Court need only find the will to try.
    I would insist upon a clear and predictable standard that calls for adversarial
    presentation of argument to the court. Such a standard would require the party with the
    burden to develop the issue, provide the party with the rights with an opportunity to
    19     Notably, the Commonwealth presently advocates, in the alternative, for a
    supplemental briefing procedure.         Brief for Commonwealth at 54-56.           The
    Commonwealth’s alternative argument has not distracted me from analyzing the asserted
    merits of its primary legal contentions.

    respond, and call upon the court to neutrally decide which side has the better of it. That
    way, the court would not bear the weight of deciding whether to take all of these
    responsibilities upon itself, and it could then decide the fate of cases based upon
    advocacy, rather than judicial intuition or navel-gazing.
    Because the Majority has a very different vision and arrives at a markedly different
    conclusion, I respectfully dissent.
