    BRIGHT v. SORENSEN
    Opinion of the Court
    in which CHIEF JUSTICE DURRANT, JUSTICE HIMONAS, JUSTICE PEARCE,
    and JUSTICE PETERSEN joined.
    ASSOCIATE CHIEF JUSTICE LEE, opinion of the Court:
    ¶1 Johannah Bright, Pia Merlo-Schmucker, and Lisa Tapp are
    former patients of Dr. Sherman Sorensen. They allege that Sorensen
    performed unnecessary heart surgery on them at Salt Lake City’s
    St. Mark’s Hospital and Murray’s Intermountain Medical Center
    between 2008 and 2011. Around 2017, each of these patients saw
    advertising for a medical malpractice attorney who specializes in
    actions arising from similar surgeries. They sought review of their
    legal claims by the Utah Department of Occupational and
    Professional Licensing (DOPL) Prelitigation Review Panel, which
    found the claims meritorious and issued certificates of compliance.
    Each former patient then filed suit against Sorensen, his business
    entity, and either St. Mark’s Hospital or IHC Health Services, Inc.,
    which operates the Intermountain Medical Center.
    ¶2 These cases were considered separately—before three
    different district judges—in the proceedings below. In each of the
    three cases the defendants moved to dismiss on the ground that the
    plaintiffs’ claims were time-barred under the Utah Health Care
    Malpractice Act (the Act). Citing the Act’s two-year limitations
    period and its four-year repose period, UTAH CODE § 78B-3-404,
    defendants asserted that the claims were time-barred given that the
    latest surgery was performed in 2011 and the lawsuits weren’t filed
    until 2017. They also contended that the time bar was not tolled by
    either the “foreign object” or “fraudulent concealment” exceptions
    set forth in the statute. See 
    id. § 78B-3-404(2).
    Defendants opposed
    tolling under the latter exception on the ground that the plaintiffs
    had failed to allege fraudulent concealment with the “particularity”
    required by rule 9(c) of the Utah Rules of Civil Procedure. And one
    of the defendants raised a separate challenge to plaintiffs’ “negligent
    credentialing” claim, asserting that it was barred by retroactive
    application of a statute enacted in 2011. See UTAH CODE § 78B-3-425.
    ¶3 The motions to dismiss were denied in large part. All three
    district judges held that defendants had failed to establish that
    plaintiffs’ claims were time-barred as a matter of law. One of the
    three judges (in the Bright case) granted the motion to dismiss as to
    the negligent credentialing claim (against St. Mark’s).
    ¶4 We granted interlocutory appeal and consolidated the three
    cases for review. We affirm the decisions denying the motions to
    2
    Cite as: 
    2020 UT 7
                             Opinion of the Court
    dismiss on time-bar grounds and reverse the decision dismissing the
    negligent credentialing claim. We hold that the fraudulent
    concealment and foreign object tolling exceptions in Utah Code
    section 78B-3-404 can extend either the limitations or repose periods.
    And we clarify that our pleading rules govern only claims and
    defenses, not responses to anticipated defenses. Because the
    plaintiffs raised their fraudulent concealment argument as a response
    to an anticipated affirmative defense (that the suits were time-
    barred), we conclude that it was subject to neither the general
    pleading rules under rule 8 nor the specialized pleading rules for
    fraud under rule 9(c). On that basis, we agree with the district courts
    that the plaintiffs have sufficiently alleged fraudulent concealment to
    avoid dismissal, and that the sufficiency of the evidence is a matter
    for summary judgment or trial.
    ¶5 We also hold that the foreign object exception applies in
    cases in which “foreign” material is wrongfully left in a patient, not
    (as here) where the material left is what was intended by a surgery.
    And we conclude that the Act does not retroactively bar plaintiffs’
    negligent credentialing claims—reversing the Bright court on this
    point. We remand to allow the plaintiffs to begin discovery aimed at
    establishing the timeliness of their complaints under the fraudulent
    concealment exception to Utah Code section 78B-3-404.
    I. BACKGROUND
    ¶6 The surgical procedure at the center of these lawsuits is
    aimed at closing a hole in the wall of tissue between the upper
    chambers of the heart. This hole, a congenital defect, is referred to as
    either a “patent foramen ovale” (PFO) or an “atrial septal defect”
    (ASD), depending on the nature of the defect. For some people with
    these heart defects, there is a risk that a blood clot will be forced
    through the hole, travel to the brain, and cause a stroke. Closing a
    PFO or ASD requires permanently implanting a medical device in
    the heart. Over time, new tissue grows over the implanted device
    and completely closes the hole.
    ¶7 Between 2002 and 2012, Sorensen, a cardiologist, held
    privileges at several Salt Lake City area hospitals, including
    St. Mark’s Hospital in Salt Lake City and Intermountain Medical
    Center in Murray. Over that decade, Sorensen performed these PFO
    and ASD closures on approximately four thousand patients at
    St. Mark’s and Intermountain Medical Center.
    ¶8 Bright, Merlo-Schmucker, and Tapp were among those
    patients who accepted Sorensen’s recommendation to let him
    perform PFO or ASD repair. Sorensen performed Tapp’s procedure
    3
    BRIGHT v. SORENSEN
    Opinion of the Court
    at Intermountain Medical Center on September 18, 2008, Bright’s
    procedure at St. Mark’s on December 15, 2009, and
    Merlo-Schmucker’s procedure at St. Mark’s on February 10, 2011.
    ¶9 According to the plaintiffs, Sorensen told them the surgeries
    were necessary to reduce their “extreme risk of debilitating stroke”
    and that the medical community recommended the procedure for
    persons in their condition. The plaintiffs further allege that other
    physicians raised concerns about Sorensen’s medical practices to
    IHC and St. Mark’s, complaining that Sorensen was regularly
    performing unnecessary, invasive cardiac procedures on his patients.
    In plaintiffs’ view, about twenty-five percent of healthy adults have
    the relevant heart defects, but the medical consensus since 2003 has
    been that PFO (or ASD) closure is appropriate only rarely—when a
    patient has experienced recurrent, unexplained strokes. But plaintiffs
    allege that Sorensen performed ten to twenty times more of these
    heart procedures than the national average for interventional
    cardiologists. And none of the plaintiffs suffered from recurrent
    strokes or had other medical conditions that would justify a PFO or
    ASD closure.
    ¶10 In 2011 IHC conducted an internal audit of Sorensen’s
    medical practice. The plaintiffs allege that the reviewers concluded
    that Sorensen had performed “multiple, medically unnecessary”
    PFO closures and thus “represented a threat to the health and safety
    of the patients treated at IHC.” That June, IHC suspended Sorensen
    for two weeks. And in September, IHC moved again to suspend
    Sorensen’s cardiac privileges. It also threatened to permanently
    suspend him and report his conduct to the National Practitioner
    Database. Sorensen resigned from the IHC medical staff in late 2011
    before it could take either of these actions.
    ¶11 Around February 2014, IHC sent a letter to its patients who
    had undergone PFO closure with a particular device implant to warn
    them about a problem with the medical device. But the letter made
    no mention of Sorensen’s suspensions, resignation, or potential
    abuse of the PFO procedure.
    ¶12 Bright and Merlo-Schmucker make related allegations
    concerning Sorenson’s relationship with St. Mark’s. They allege that
    St. Mark’s retained Sorensen on its medical staff until his retirement
    in 2011, even though it was aware that IHC had suspended Sorensen
    for performing unnecessary heart procedures.
    ¶13 In 2015, some of Sorensen’s former patients began to see
    advertising by a medical malpractice attorney who specializes in
    actions arising from PFO and ASD procedures. The plaintiffs in this
    4
    Cite as: 
    2020 UT 7
                             Opinion of the Court
    case allege that they only realized they might have undergone an
    unnecessary heart procedure once they saw this advertising.1
    ¶14 In January 2017 the plaintiffs applied for prelitigation
    review of their medical malpractice claims as required at that
    time under the Act. 2 UTAH CODE § 78B-3-412(1) (since held
    unconstitutional by Vega v. Jordan Valley Med. Ctr., LP, 
    2019 UT 35
    ,
    ¶ 25, 
    449 P.3d 31
    ). Bright and Merlo-Schmucker filed their requests
    with the Utah Division of Occupational and Professional Licensing
    (DOPL) review panel on January 3. Tapp submitted her request on
    January 17.
    ¶15 The DOPL prelitigation panel found each patient’s claims
    meritorious and issued certificates of compliance with the
    prelitigation procedures. Following the prelitigation review process,
    Bright, Melo-Schmucker, and Tapp filed separate suits against
    Sorensen and the hospitals where their procedures were performed.
    ¶16 The plaintiffs brought claims for negligence, negligent
    credentialing, and fraud. The amended complaints alleged that
    Sorensen, IHC, and St. Mark’s took affirmative acts to fraudulently
    conceal the unnecessary surgeries. Specifically, the complaints
    alleged that Sorensen and the hospitals “created false statements and
    documents to conceal the fact that Sorensen was performing
    medically unnecessary closures,” going so far as to falsify patients’
    medical charts.
    ¶17 Bright, Merlo-Schmucker, and Tapp join more than a
    thousand other patients with pending medical malpractice actions
    against Sorensen and the hospitals where he performed PFO and
    ASD closures. The claims are similar, and in the cases consolidated
    before us, substantially the same.
    _____________________________________________________________
    1 Tapp alleges that she was put on notice in 2017, while Merlo-
    Schmucker and Bright allege in their complaints, filed on September
    26, 2017, and October 23, 2017, respectively, that they were put on
    notice “recently.”
    2 This was the relevant date for the Utah Health Care Malpractice
    Act’s statutes of limitations and repose. UTAH CODE § 78B-3-416(3)(a)
    (“The filing of a request for prelitigation panel review under this
    section tolls the applicable statute of limitations . . . .”); Jensen v.
    Intermountain Healthcare Inc., 
    2018 UT 27
    , ¶ 34, 
    424 P.3d 885
    (ruling
    that a request for prelitigation review tolls the statute of repose).
    5
    BRIGHT v. SORENSEN
    Opinion of the Court
    ¶18 In the Bright, Merlo-Schmucker, and Tapp cases, Sorensen
    and the hospitals filed motions to dismiss on the ground that the
    plaintiffs’ claims are barred by the Utah Health Care Malpractice
    Act’s four-year statute of repose. UTAH CODE § 78B-3-404(1). Citing
    this statute, the defendants asserted that the plaintiffs’ claims had
    not been filed within four years after the date of the allegedly
    unnecessary surgeries and the time bar was not tolled by either the
    “fraudulent concealment” or “foreign object” exceptions set forth in
    the statute. See 
    id. § 78B-3-404(2).
    As to “fraudulent concealment,”
    the defendants asserted that the claims should be dismissed because
    the plaintiffs had failed to plead fraudulent concealment with
    sufficient particularity. Sorensen also argued that the negligent
    credentialing claims should be dismissed on the ground that
    negligent credentialing is no longer a cause of action under Utah
    Code section 78B-3-425.
    ¶19 All three district courts denied the defendants’ motions to
    dismiss in large part. Each court concluded that the plaintiffs could
    proceed with their claims under the fraudulent concealment
    exception, which provides a one-year extension to the statute of
    repose. UTAH CODE § 78B-3-404(2)(b). On the question whether the
    plaintiffs had actually filed within one year of discovering the
    alleged fraudulent concealment, the courts concluded that this was a
    matter for summary judgment or trial—not for a motion to dismiss.
    The district court judges disagreed on one final point. The court in
    the Bright case granted the motion to dismiss on the negligent
    credentialing claim, while the courts in the Merlo-Schmucker and
    Tapp cases allowed the negligent credentialing claims to proceed.3
    ¶20 Before the start of discovery, Sorensen, St. Mark’s, and IHC
    filed a request for leave to file an interlocutory appeal in each of the
    three cases. We granted that request and agreed to consolidation of
    the cases on appeal.
    II. DISCUSSION
    ¶21 For medical malpractice claims, Utah Code section
    78B-3-404(1) establishes a two-year limitations period and a
    four-year repose period. Such claims must be “commenced within
    two years after the plaintiff or patient discovers, or through the use
    _____________________________________________________________
    3 The Merlo-Schmucker and Tapp courts did not address
    negligent credentialing in their orders.
    6
    Cite as: 
    2020 UT 7
                             Opinion of the Court
    of reasonable diligence should have discovered the injury,
    whichever first occurs, but not to exceed four years after the date of
    the alleged act, omission, neglect, or occurrence.” UTAH CODE § 78B-
    3-404(1).
    ¶22 The statute also sets forth exceptions in the form of tolling
    provisions. Tolling is provided for actions where there is an
    allegation “that a foreign object has been wrongfully left within a
    patient’s body,” and actions “where it is alleged that a patient has
    been prevented from discovering misconduct on the part of a health
    care provider because that health care provider has affirmatively
    acted to fraudulently conceal the alleged misconduct.” 
    Id. § 78B-3-404(2).
       ¶23 The above-quoted provisions form the backdrop of most of
    the arguments before us on this interlocutory appeal. One additional
    provision is also relevant—a 2011 amendment to the Utah
    Healthcare Malpractice Act, which eliminated “negligent
    credentialing” as a cause of action. See UTAH CODE § 78B-3-425.
    ¶24 On appeal defendants raise five sets of issues relating to the
    operation of these provisions: (a) whether the statute’s tolling
    exceptions apply to the repose period (or just the limitations period);
    (b) whether allegations of “fraudulent concealment” are subject to a
    requirement of heightened pleading under civil rule 9(c); (c) whether
    defendants were entitled to dismissal in light of plaintiffs’ allegations
    of fraudulent concealment; (d) whether the tolling exception for a
    “foreign object” wrongfully left within a patient can apply here; and
    (e) whether amendments to the statute retroactively bar negligent
    credentialing claims.
    ¶25 We affirm the decisions denying defendants’ motions to
    dismiss and endorse the plaintiffs’ positions for the most part. We
    hold that the tolling provisions apply to both the repose period and
    the limitations period, conclude that there is no heightened or other
    pleading requirement for a plaintiff in responding to an anticipated
    affirmative defense, uphold the determination that the question of
    fraudulent concealment is a matter for summary judgment or trial,
    determine that the foreign object exception does not apply, and hold
    that the 2011 amendments do not apply retroactively.
    A. Tolling and the Four-Year Repose Period
    ¶26 A threshold question is whether the four-year repose period
    in subsection 404(1) is subject to the tolling provisions in subsection
    7
    BRIGHT v. SORENSEN
    Opinion of the Court
    404(2). Sorensen claims that the “foreign object” and “fraudulent
    concealment” exceptions in section 404(2) apply only to the two-year
    limitations period in section 404(1). 4 He views the four-year repose
    period as a hard-and-fast time-bar that can never be extended—even
    in actions involving a foreign object left in a patient or fraudulent
    concealment of alleged misconduct.
    ¶27 Sorensen thus views the four-year repose period as a
    categorical bar. He sees this as the whole point of a statute of
    repose—to set a hard cutoff for claims filed after a given event
    (without regard to discovery of the basis for a claim). And he views
    tolling as purely a matter for a statute of limitations, which is (at
    least often) triggered not by an event but by discovery of the basis
    for a claim.
    ¶28 Sorensen’s view may reflect the ordinary operation of
    statutes of repose generally.5 But it is incompatible with the text and
    structure of this statute of repose. And it is of course this statute of
    repose that we are called upon to interpret.
    ¶29 Subsection 404(1) presents both the two-year limitations
    period and the four-year repose period in a unitary time-bar
    provision. And subsection 404(2), in turn, modifies the time-bar
    provision in its entirety. The prefatory clause of 404(2) is telling. It
    states that the tolling provisions set forth in 404(2) apply
    “Notwithstanding Subsection (1).” 
    Id. § 78B-3-404(2).
    This is a clear
    signal that the tolling provisions that follow (for actions involving a
    “foreign object” or “fraudulent concealment”) are general limitations
    on “Subsection (1)”—not just a cherry-picked subpart of that
    _____________________________________________________________
    4 The plaintiffs argue the opposite—that the exceptions modify
    only the repose period. But the plaintiffs’ position is similarly
    incompatible with the terms and structure of the statute. And the
    cases the plaintiffs cite, such as Day v. Meek, 
    1999 UT 28
    , 
    976 P.2d 1202
    , interpret an earlier version of the Act, with structure quite
    distinct from that in place today.
    5See Cal. Pub. Emp’s’ Ret. Sys. v. ANZ Sec., Inc., 
    137 S. Ct. 2042
    ,
    2051 (2017) (“By establishing a fixed limit, a statute of repose
    implements a legislative decision that as a matter of policy there
    should be a specific time beyond which a defendant should no
    longer be subjected to protracted liability” (internal citation and
    quotation marks omitted)).

    Cite as: 
    2020 UT 7
                            Opinion of the Court
    subsection. We see no way to read the terms of section 404
    otherwise.
    ¶30 The exceptions in subsection 78B-3-404(2) thus apply to both
    the limitations period and the repose period in subsection
    78B-3-404(1). As with the limitations period, the repose period is
    subject to extension if the statutory tolling provisions are satisfied.
    Thus, the discovery of a foreign object left in a patient or the
    fraudulent concealment of alleged misconduct may extend either the
    limitations period or the repose period by one year.
    ¶31 In so holding we reject a further argument advanced by
    defendants—that this construction of the statute could give a litigant
    less than two years to file suit. Defendants posit a circumstance in
    which fraud is discovered early on, perhaps one month after a
    medical procedure is performed. If the filing period is determined
    solely by the one-year period of limitation following discovery,
    defendants contend that the plaintiff would have only one year and
    one month to file her claim.
    ¶32 We disagree. Defendants’ position is again rooted in a
    misunderstanding of the interaction between subsections 404(1) and
    404(2)—and the function of the “Notwithstanding” clause in 404(2).
    The one-year extensions provided in subsection 404(2) are not
    independent, freestanding limitations periods. They are exceptions
    that may extend the time periods in subsection 404(1). This, again, is
    confirmed by the “Notwithstanding” clause—a legal construct that
    “clearly signals the drafter’s intention that the provisions of the
    ‘notwithstanding’ section override conflicting provisions of any
    other section.” Cisneros v. Alpine Ridge Grp., 
    508 U.S. 10
    , 18 (1993).
    ¶33 This confirms our interpretation and avoids the problem
    alluded to by defendants. The foreign object and fraudulent
    concealment provisions are not independent time bars; they are
    exceptions that may extend the otherwise “conflicting” limitations
    and repose periods found in Utah Code section 78B-3-404(1).
    B. Fraudulent Concealment and Heightened Pleading
    ¶34 Another question concerns the pleading burden of a plaintiff
    with regard to the exception for “fraudulent concealment.”
    Defendants’ position is straightforward: Utah Code section
    78B-3-404(2) speaks of “fraudulent concealment,” and civil rule 9(c)
    requires allegations of “fraud” to be made with particularity.
    Because the complaints in this action purportedly failed to allege
    fraudulent concealment with sufficient particularity, defendants
    assert that the complaints were subject to dismissal under rule 9(c).
    9
    BRIGHT v. SORENSEN
    Opinion of the Court
    ¶35 Defendants’ point has some facial plausibility. But it misses
    a threshold nuance. Our pleading rules speak only to particularity in
    pleading, and pleadings are limited to allegations of claims and
    defenses. See UTAH R. CIV. P. 7 (pleadings allowed include
    complaints and answers but not anticipated responses to affirmative
    defenses); 
    id. 8 (prescribing
    the level of detail to be included in
    “claims for relief” and “affirmative defenses”); 
    id. 9(c) (requiring,
    as
    an exception to rule 8, more particularity as to certain allegations).6
    Any allegations of “fraudulent concealment” in the complaints in
    these actions were thus not governed by our pleading rules because
    fraudulent concealment is not an element of a plaintiff’s claim, but
    an anticipatory response to an expected affirmative defense.
    ¶36 The contents of plaintiffs’ “claims for relief” are governed by
    rules 8 and 9(c). But plaintiffs’ claims for relief are claims sounding
    in medical malpractice. Fraudulent concealment is raised as a
    response to an anticipated affirmative defense—that plaintiffs’
    claims are time-barred. Granted, plaintiffs included some allegations
    about defendants’ alleged fraudulent concealment. But plaintiffs had
    no obligation to do so. That obligation is not found in our rules of
    procedure, since as noted above, those rules speak only to the
    requirements of a plaintiff in pleading “claims for relief” and to the
    requirements of a defendant in pleading “affirmative defenses.”
    ¶37 And the obligation is likewise not found in Utah Code
    section 78B-3-404(2). Defendants say that the statute includes a
    requirement of particularized pleading. But we see nothing in the
    statute that speaks to this question. “[I]n an action where it is alleged
    that a patient has been prevented from discovering misconduct on
    the part of a health care provider because that health care provider
    has affirmatively acted to fraudulently conceal the alleged
    misconduct,” the statute says that “the claim shall be barred unless
    commenced within one year after the plaintiff or patient discovers,
    or through the use of reasonable diligence, should have discovered
    the fraudulent concealment, whichever first occurs.” UTAH CODE
    § 78B-3-404(2)(b). There is a reference here to a party “alleg[ing]”
    fraudulent concealment. But in context, the statute is speaking only
    _____________________________________________________________
    6 Rule 9 “supplements but does not supplant Rule 8[’s] notice
    pleading” standard. United States ex rel. Grubbs v. Kanneganti, 
    565 F.3d 180
    , 186 (5th Cir. 2009). It thus governs the level of particularity
    required for allegations of fraud only if such allegations go to a claim
    for relief or an affirmative defense.

                             Opinion of the Court
    to what must be established to invoke the exception to the statute of
    limitations or repose. How the allegation must be made is not dealt
    with. And that is a matter governed by the Utah Rules of Civil
    Procedure.7
    ¶38 The legislature, in any event, lacks the power to amend our
    rules of procedure except by a joint resolution adopted by a
    supermajority vote. See Brown v. Cox, 
    2017 UT 3
    , ¶¶ 17–18, 
    387 P.3d 1040
    . There is no indication that those requirements were fulfilled
    here. And unless and until the legislature follows those requirements
    we are in no position to conclude that it has altered our established
    rules of procedure.
    ¶39 For these reasons we hold that a plaintiff has no obligation
    to plead fraudulent concealment under Utah Code section
    78B-3-404(2) with particularity—or even at the level of “notice
    pleading” required by rule 8(a). Because fraudulent concealment
    under this statute is not an element of a defense, but just an
    anticipatory response to an expected affirmative defense, there is no
    pleading obligation on the plaintiff’s part. The plaintiff is entitled to
    ignore the question of fraudulent concealment altogether—to wait to
    see whether the defendant will raise a time-bar defense in an answer,
    and to address that defense through other procedural mechanisms as
    they present themselves later.
    ¶40 Not all plaintiffs will choose that route, of course. And the
    plaintiffs in these cases did not choose to stay mum. They included
    some allegations on the question of fraudulent concealment in their
    complaints. And we are not suggesting that these allegations were
    irrelevant—or in any way insulated the plaintiffs’ claims from
    summary dismissal.
    _____________________________________________________________
    7 At oral argument in this case, counsel for the defendants raised
    the concern that the constraints of our heightened pleading rules are
    a necessary brake on the possibility that a plaintiff might make bare,
    unsupported allegations of fraudulent concealment in a bid to open
    up a “fishing expedition” in discovery. But this misses the fact that
    our rules contain other limitations on such practice—including the
    rule 11 requirement that all allegations “have evidentiary support”
    or at least (if “specifically so identified”) be “likely to have
    evidentiary support after a reasonable opportunity for further
    investigation or discovery.” UTAH R. CIV. P. 11(b)(3). And our
    decision today in no way eliminates any of these limits.
    11
    BRIGHT v. SORENSEN
    Opinion of the Court
    ¶41 It has oft been observed that a plaintiff may plead her way
    out of court by including too much detail (or the wrong kind of
    detail) in a complaint.8 That could certainly happen in a case like this
    one. On a motion for judgment on the pleadings, or for failure to
    plead a claim for which relief may be granted, the court is to accept
    the plaintiffs’ factual allegations as true. See Peck v. State, 
    2008 UT 39
    ,
    ¶ 2, 
    191 P.3d 4
    . With that in mind, a plaintiff who includes detailed
    allegations of relevance to an anticipated statute of limitations
    defense (and her anticipated response thereto) does so at her peril.
    Where a motion to dismiss is filed based on the anticipated defense,
    the district court is entitled to either rule on the pleadings or to allow
    the parties to convert the motion to a motion for summary judgment
    if further factual development is necessary.
    ¶42 This is the framework we endorsed in our decision in Tucker
    v. State Farm Mutual Automobile Insurance Co., 
    2002 UT 54
    , 
    53 P.3d 947
    . There we said that a 12(b)(6) motion is an appropriate vehicle
    for seeking dismissal on statute of limitations grounds. 
    Id. ¶¶ 8–9.
    But we emphasized that the basis for such a dismissal must be
    evident on the face of the complaint. 
    Id. ¶ 8.
    And where the detail
    necessary to establish a basis for dismissal on statute of limitations
    grounds is not set forth on the face of the complaint, we
    acknowledged the discretion of the district court to either deny the
    motion or open the door to conversion to a motion for summary
    judgment. 
    Id. ¶¶ 10–11.
        ¶43 The cases cited by the defendants are not to the contrary.
    These cases hold that a defendant may file a motion to dismiss a
    facially untimely complaint under rule 12(b)(6). See, e.g., 
    id. ¶¶ 7–11;
    Boettcher v. Conoco Phillips, Co., 721 F. App’x. 823, 824–25 (10th Cir.
    2018).9 When the plaintiff pleads the basis for a motion to dismiss on

    216 F.3d 1111
    , 1116
    (D.C. Cir. 2000) (explaining that “it is possible for a plaintiff to plead
    too much: that is, to plead himself out of court by alleging facts that
    render success on the merits impossible”); Jackson v. Marion Cty., 
    66 F.3d 151
    , 153 (7th Cir. 1995) (noting that “a plaintiff
    can plead himself out of court by alleging facts which show that he
    has no claim, even though he was not required to allege those
    facts”).

    statute of limitations grounds and such a motion is filed, the case law
    says that “the plaintiff has the burden of establishing a factual basis
    for tolling the statute.” Aldrich v. McCulloch Props., Inc., 
    627 F.2d 1036
    , 1041 n.4 (10th Cir. 1980). That is correct so far as it goes. When
    a complaint is facially untimely, a plaintiff must affirmatively
    advance an exception to the applicable statute of limitations to avoid
    dismissal. But it does not follow that a plaintiff who wishes to invoke
    such an exception must do so in compliance with rules 8 and 9. The
    exception remains a response to a statute of limitations defense. It is
    thus outside the domain of rules 8 and 9. The plaintiff’s “burden”
    therefore, is not a pleading burden, but a burden of proof or
    persuasion in response to a defendant’s motion to dismiss. A
    plaintiff could carry that burden, in other words, by advancing legal
    and factual support for the alleged exception to the time-bar
    defense—in material that may lead to the conversion of the motion
    to dismiss to a motion for summary judgment.
    ¶44 Most of the other cases cited by the defendants are in line
    with this view. Granted, we have said that the 9(c) particularity rule
    extends to a plaintiff’s allegation of a claim for fraud or a defendant’s
    assertion of an affirmative defense sounding in fraud. 10 And in a
    summary judgment setting, we have concededly required a party
    advancing an allegation of fraud (even in response to an affirmative
    defense) to carry the burden of proving fraud.11 But our cases have
    never held that the pleading requirements of our rules extend to a
    mere response to an anticipated affirmative defense.

    ,

    13
    BRIGHT v. SORENSEN
    Opinion of the Court
    ¶45 The closest we have come is in dicta in Chapman By and
    Through Chapman v. Primary Children’s Hospital, 
    784 P.2d 1181
    (Utah
    1989). In Chapman, this court held that the fraudulent concealment
    exception to the Utah Health Care Malpractice Act was satisfied
    when plaintiffs made an independent claim for fraudulent
    concealment (rather than simply alleging fraudulent concealment to
    invoke the statutory tolling exception). 
    Id. at 1184–85.
    With that in
    mind, the Chapman court assumed the existence of a requirement
    that fraudulent concealment alleged as a response to an affirmative
    defense be pleaded with particularity. Chapman found the fraudulent
    concealment allegations in that case “sufficiently clear and specific”
    to show that “the requirement of rule 9(b)[12] ha[d] been met.” 
    Id. at 1186.
    But the question presented in today’s case was never directly
    addressed. We never decided whether a mere response to an
    anticipated affirmative defense is subject to rules 8 and 9 because we
    were not faced with a case in which particularized pleading was
    lacking. Chapman, moreover, was decided on summary judgment.13
    ¶46 For these reasons, the Chapman court’s assumption that
    particularity is required for a response to an affirmative defense is
    mere dicta. And dicta pertaining to our rules of procedure implicates
    minimal reliance interests and, accordingly, little stare decisis weight.
    See Eldridge v. Johndrow, 
    2015 UT 21
    , ¶¶ 35–36, 
    345 P.3d 553
    (noting
    that the degree of reliance on a precedent is a factor in whether to
    afford stare decisis deference); see also Payne v. Tennessee, 
    501 U.S. 808
    ,
    828 (1991) (explaining that “[c]onsiderations in favor
    of stare decisis are at their acme in cases . . . where reliance interests
    are involved” and that “the opposite is true in cases such as the
    present one involving procedural and evidentiary rules”).
    ¶47 Chapman merely assumed, without deciding, that
    particularity is required to allege fraudulent concealment in response
    to an anticipated affirmative defense (untimeliness). It left the door
    open for this court to reconsider the question in a case like this one
    _____________________________________________________________
    12Rule 9 has been amended and restructured in the time since
    Chapman and some of the other cases cited here. The particularity
    requirement that is now in 9(c) used to be in 9(b).
    13 The same goes for our decision in 
    Norton, 669 P.2d at 858
    . That
    case was also decided on summary judgment. See 
    id. And any
    references to a particularity-in-pleading requirement for a response
    to an anticipated defense were pure dicta.

    2020 UT 7
                             Opinion of the Court
    where it is squarely presented. In doing so today, we hold that a
    response to an affirmative defense is not governed by the pleading
    requirements of rules 8 and 9 of the Utah Rules of Civil Procedure.14
    And we repudiate any dicta to the contrary in Chapman.
    C. Plaintiffs’ Allegations of Fraudulent Concealment
    ¶48 The next question is whether defendants were entitled to
    dismissal in light of the plaintiffs’ allegations of fraudulent
    concealment. Our rejection of the 9(c) argument goes a long way
    toward resolving this question. Because plaintiffs had no burden of
    pleading fraudulent concealment (with particularity or otherwise),
    the only question is whether they pleaded themselves out of court
    with the detail they chose to include in their complaints—by
    pleading detail that was not required, but that nonetheless
    established that their claims were time-barred as a matter of law.
    And we conclude that they did not.
    ¶49 Under section 404(2)(b) the first question is whether
    plaintiffs were “prevented from discovering misconduct on the part
    of a health care provider because that health care provider has
    affirmatively acted to fraudulently conceal the alleged misconduct.”
    UTAH CODE § 78B-3-404(2)(b). If such fraudulent concealment is
    shown, an otherwise time-barred claim is timely if “commenced
    within one year after the plaintiff or patient discovers, or through the
    use of reasonable diligence, should have discovered the fraudulent
    concealment, whichever first occurs.” 
    Id. ¶50 Plaintiffs
    in no way pleaded a basis for dismissal under
    these provisions. Bright, Merlo-Schmucker, and Tapp each alleged in
    their complaints that Sorensen and the hospitals “took affirmative
    steps to conceal Plaintiff[s’] cause[s] of action.” They also alleged
    that “[b]ecause of Defendants’ concealment of material facts and
    misleading conduct, Plaintiff[s] [were] not aware of [their] causes of
    action.” Specifically, plaintiffs alleged that Sorensen and the
    hospitals “created false statements and documents to conceal the fact
    that Sorensen was performing medically unnecessary closures,”
    including false medical charts.
    _____________________________________________________________
    14Our decision in Russell Packard Development, Inc. v. Carson, 
    2005 UT 14
    , 
    108 P.3d 741
    , is not controlling because the rule 9(c) question
    was not raised. But the case is in line with our decision here, in that it
    found a prima facie showing of fraudulent concealment sufficient to
    defeat a motion to dismiss on statute of limitations grounds.
    15
    BRIGHT v. SORENSEN
    Opinion of the Court
    ¶51 Plaintiffs further alleged that they first realized they had
    potential causes of action soon before filing suit in 2017. They
    asserted that “a reasonable plaintiff would not have discovered the
    cause[s] of action earlier” and that “[p]laintiff[s] did not know, nor
    should have known, of the causes of action against Defendants prior
    to being put on notice of Defendants’ potential liability” because
    they “neither discovered, nor reasonably should have discovered,
    the facts underlying [their] causes of action before any proffered
    statute of limitations period expired.”
    ¶52 Plaintiffs thus made all of the allegations that the Act
    requires in order to toll the statute of limitations period. Again, they
    had no obligation to plead the terms and conditions of fraudulent
    concealment. Because they nonetheless chose to do so, the question
    is whether they provided a basis for dismissal as a matter of law on
    the face of their complaints. They clearly did not.
    ¶53 We affirm the district courts’ denials of the defendants’
    motions to dismiss on this basis. In so doing we do not suggest that
    the plaintiffs’ position on fraudulent concealment is meritorious. Nor
    do we foreclose the possibility of disposition of the fraudulent
    concealment question as a matter of law—on a future motion for
    summary judgment, for example, after any discovery or other
    necessary proceedings.
    D. The Foreign Object Exception
    ¶54 The next question concerns the applicability of the “foreign
    object” exception under Utah Code section 78B-3-404(2)(a). This
    exception provides that if an “allegation against the health care
    provider is that a foreign object has been wrongfully left within a
    patient’s body, the claim shall be barred unless commenced within
    one year after the plaintiff or patient discovers, or through the use of
    reasonable diligence should have discovered, the existence of the
    foreign object wrongly left in the patient’s body, whichever first
    occurs.” UTAH CODE § 78B-3-404(2)(a).
    ¶55 Plaintiffs ask us to endorse a construction of “foreign object”
    that encompasses the medical devices that were placed in their
    bodies during the surgeries in question. They cite a sense of foreign
    encompassing anything that “does not exist naturally in the body.”
    That is one sense of foreign. See Foreign, AMERICAN HERITAGE
    DICTIONARY (5th ed. 2011) (defining “foreign” as “not natural;
    alien”). But it is not the only sense of the term. Sometimes foreign
    means “[s]ituated in an abnormal or improper place in the body and
    typically introduced from outside.” See 
    id. 16 Cite
    as: 
    2020 UT 7
                              Opinion of the Court
    ¶56 The choice between these senses of foreign is the key to the
    applicability of the foreign object exception. A medical device, after
    all, is foreign in the sense of not existing naturally in the body, but not
    foreign in the sense of being “in an abnormal or improper place in the
    body.” So we must thus choose between the unnatural and improper
    place senses of foreign to resolve this case.
    ¶57 We have identified various means of resolving a contest
    between competing senses of a statutory term. One approach is to
    look for the more ordinary sense of the term as used in a database of
    naturally occurring language—a linguistic corpus. 15 We have
    pursued that avenue here. We have searched for uses of the term
    “foreign object” in the News on the Web (NOW) Corpus in the
    context of medical procedures. 16 This kind of search allows us to
    assemble empirical data on the range of uses of “foreign object” as a

    identifying ordinary meaning); State v. Rasabout,

    further).
    16  The NOW corpus is available at https://www.english-
    corpora.org/now/. It “contains 9.0 billion words of data from
    web-based newspapers and magazines from 2010 to the present
    time.” 
    Id. We began
    by searching for “foreign object” within five
    words of the collocates “surgery” and “procedure,” but these
    searches yielded only six and two concordance lines of text,
    respectively. So instead we looked through all concordance lines of
    text associated with the top 100 collocates that show up most
    frequently within five words of the phrase “foreign object”—
    searching for concordance lines relating to medical procedures or
    surgery. Collocates with relevant concordance lines of text included
    “bodies”, “body”, “caused”, “causing”, “immune”, “inside”,
    “patient”, “penis”, “presence”, “putting”, “remove”, “retained”,
    “surgery”, and “vagina.” We also performed a similar search in the
    Corpus of Contemporary American English (COCA)—a corpus we
    have employed in prior cases. See Richards, 
    2019 UT 57
    , ¶ 21. But we
    found only three concordance lines of text that fit our search
    criteria—not enough data to be useful.

    Opinion of the Court
    phrase. 17 It also allows us to look for the use of this term in the
    context of relevance here—medical procedures. 18 By examining
    “concordance lines” of text from a corpus, we can discern whether
    and to what extent ordinary speakers of English speak of a “foreign
    object” in the context of surgery in reference to all things not existing
    naturally in the body or only in reference to things in an abnormal or
    improper place in the body. We have done that here.
    ¶58 In this instance, however, our corpus analysis was
    inconclusive. 19 We found thirty-four concordance lines of text
    meeting our search criteria, and the above two senses of foreign were
    about evenly represented: sixteen of the concordance lines evidenced
    the improper place sense of “foreign object” (in that they involve items
    left unintentionally after surgery) 20 and eighteen evidenced the

    tell us that the phrase “foreign object” is used in the context of
    surgery to refer commonly to both an item left in an improper place
    and an item that is unnatural to the body. And that requires us to
    look to other interpretive tools to identify the ordinary meaning of
    the statutory text in this linguistic setting.22
    ¶60 One important tool is an examination of the structural and
    linguistic context of the statute in question. See Olsen v. Eagle

    BRIGHT v. SORENSEN
    Opinion of the Court
    ¶61 Here the statutory context does eliminate the ambiguity. In
    the context of the language and structure of the foreign object
    exception to the statutory time-bars, “foreign object” cannot be
    viewed to encompass all objects that are merely unnatural to the
    body; it can only be viewed to extend to objects that are in an
    improper place.
    ¶62 The statute identifies the “discovery” of a foreign object as
    the moment at which this exception is triggered. UTAH CODE
    § 78B-3-404(2)(a). And discovery presupposes the placement of an
    object that was not the intended point of the surgery. See Discover,
    AMERICAN HERITAGE DICTIONARY (5th ed. 2011) (defining “discover”
    as “[t]o learn about for the first time in one’s experience”). That
    forecloses the unnatural sense of “foreign object.” Sorensen’s patients
    could not be said to have later discovered the placement of a medical
    device that was the very point of their surgery. So the term discovery
    confirms that foreign objects are things left by mistake—in an
    improper place.
    ¶63 That conclusion is reinforced by the statute’s reference to
    “foreign object[s] wrongfully left in [a] patient’s body.” UTAH CODE
    § 78B-3-404(2)(a) (emphasis added). There is nothing wrongful about
    the placement of sutures or medical devices that are the intended
    design of a surgery. Those things may be said to be foreign in the
    sense of being unnatural to the body. But the statutory reference to
    wrongful makes clear that an object is foreign in this statute only if it
    was in an improper place.
    ¶64 We reject the plaintiffs’ conception of “foreign object” on
    this basis. In light of the language and structure of the statute, we
    hold that the “foreign object” exception extends only to objects
    wrongfully left in an improper place. The exception thus includes
    implements used during surgery but meant to be removed (like a
    sponge or clamp), or objects accidentally introduced into the body
    during surgery (like a Junior Mint 23 ). But it does not extend to
    medical devices or implants that are the very point of a medical
    procedure.

    a Junior Mint from an elevated observatory in an operating room,
    where it fell “into the patient,” George wondering how the surgeons
    could “not notice it,” and Jerry explaining that “it’s a little mint”—“a
    Junior Mint”).

                             Opinion of the Court
    ¶65 Medical implants are not transformed into discoverable,
    wrongfully placed foreign objects when a patient later concludes that
    a surgery was unnecessary. We reject the plaintiffs’ argument on the
    above grounds and hold that the foreign object exception is
    inapplicable in the circumstances of this case.
    E. Negligent Credentialing
    ¶66 The final question presented concerns the viability of
    plaintiffs’ negligent credentialing claims. Our legislature foreclosed
    the viability of such claims in a statute enacted in 2011. UTAH CODE
    § 78B-3-425 (enacting as “the policy of this state that the question of
    negligent credentialing, as applied to health care providers in
    malpractice suits, is not recognized as a cause of action”).
    ¶67 St. Mark’s acknowledges that the surgeries in question were
    performed prior to the effective date of this provision. But it
    nonetheless asks us to apply this statute retroactively, and thus to
    hold that plaintiffs Bright and Merlo-Schmucker are barred from
    asserting claims for negligent credentialing.24
    ¶68 This position is foreclosed by our decision in Waddoups v.
    Noorda, 
    2013 UT 64
    , ¶ 13, 
    321 P.3d 1108
    . In the Waddoups case we
    expressly held that “section 78B-3-425 of the Utah Code does not
    apply retroactively to bar negligent credentialing claims that arose
    prior to its enactment.” 
    Id. We reinforce
    that decision here. And we
    thus reject the position advanced by St. Mark’s and reverse the
    district court in the Bright case (the only court to have ruled on this
    issue), which dismissed Bright’s negligent credentialing claim under
    Utah Code section 78B-3-425.
    III. CONCLUSION
    ¶69 We affirm the denial of defendants’ motions to dismiss. In
    so doing we conclude that the statutory tolling provisions in Utah
    Code section 78B-3-404(2) apply to both the two-year limitations
    period and the four-year repose period in section 78B-3-404(1). We
    also hold that responses to affirmative defenses are not subject to the
    pleading requirements of rules 8 and 9 of the Utah Rules of Civil
    Procedure. And we hold that the “foreign object” exception in
    section 78B-3-404(2) does not apply here and that negligent
    credentialing claims are not foreclosed by retroactive application of
    _____________________________________________________________

    BRIGHT v. SORENSEN
    Opinion of the Court
    section 78B-3-425. We accordingly remand for further proceedings
    consistent with this opinion.
    ¶70 In remanding we are not endorsing the timeliness of
    plaintiffs’ claims under the “fraudulent concealment” exception. We
    are simply upholding the plaintiffs’ opportunity to develop and
    present evidence in support of this exception, through discovery and
    subject to further motions under applicable rules of civil procedure.
