    Plaintiffs – issuers of collateralized debt obligations secured by certificates
    in residential-mortgage-backed securities trusts – appeal from three separate
    judgments dismissing actions brought against The Bank of New York Mellon,
    Deutsche Bank National Trust Company, and Deutsche Bank Trust Company
    Americas. In each case, the district courts (Caproni and Koeltl, JJ.) assumed that
    Plaintiffs had Article III standing, but found that Plaintiffs were precluded from
    relitigating the issue of prudential standing due to a prior case Plaintiffs had
    brought against U.S. Bank National Association. See Phx. Light SF DAC v. U.S.
    Bank Nat’l Ass’n, No. 20-1312,

    the question of Article III standing to address issue preclusion, which offered a
    threshold, non-merits basis for dismissal. See Snoqualmie Indian Tribe v.

    RICHARD J. SULLIVAN, Circuit Judge:
    Plaintiffs – issuers of collateralized debt obligations (“CDOs”) secured by
    certificates in residential-mortgage-backed securities (“RMBS”) trusts – appeal
    from three separate judgments dismissing actions brought against The Bank of
    New York Mellon (“BNY Mellon”) and Deutsche Bank National Trust Company
    and Deutsche Bank Trust Company Americas (together, “Deutsche Bank”), which
    served as either trustee or master servicer of the RMBS trusts. In each case, the
    district courts (Caproni and Koeltl, JJ.) assumed that Plaintiffs had Article III
    standing, but found that Plaintiffs were precluded from relitigating the issue of
    prudential standing due to a prior case Plaintiffs had brought against U.S. Bank
    National Association (“U.S. Bank”). See Phx. Light SF DAC v. U.S. Bank Nat’l Ass’n,
    No. 20-1312, 
    2021 WL 4515256
     (2d Cir. Oct. 4, 2021), cert. denied, 
    142 S. Ct. 1371 (2022)
    . In resolving an issue of first impression in this Circuit, we join the Ninth
    Circuit in concluding that the district courts permissibly bypassed the question of
    Article III standing to address issue preclusion, which offered a threshold, non-
    merits basis for dismissal. See Snoqualmie Indian Tribe v. Washington, 
    8 F.4th 853
    (9th Cir. 2021), cert. denied, 
    142 S. Ct. 2651 (2022)
    . We also conclude that the district
    4
    courts’ application of issue preclusion was correct. We therefore AFFIRM the
    orders of the district courts in all three appeals.
    I.   BACKGROUND
    Plaintiffs are issuers of CDOs, meaning that they issued notes secured by a
    portfolio of assets, including certificates in RMBS trusts. In 2014, seeking to
    recover losses from their RMBS investments in the wake of the 2008 collapse of the
    housing market, Plaintiffs brought various suits against RMBS trustees, including
    U.S. Bank, BNY Mellon, and Deutsche Bank (the “U.S. Bank Action,” the “BNY
    Mellon 2014 Action,” and the “Deutsche Bank Action,” respectively). However,
    in 2015, the district court in the U.S. Bank Action granted the defendant’s motion
    to dismiss under Federal Rule of Civil Procedure 12(b)(1). See Phx. Light SF Ltd. v.
    U.S. Bank Nat’l Ass’n, No. 14-cv-10116 (KBF), 
    2015 WL 2359358
    , at *1 (S.D.N.Y. May
    18, 2015). In particular, the district court found that Plaintiffs lacked standing
    because, when they issued their CDO notes, they simultaneously conveyed all
    right, title, and interest in the RMBS certificates – including the full power to file
    actions regarding rights under the RMBS certificates – to other entities (the “CDO
    Trustees”). See 
    id.
     at *2–4.
    5
    Following that decision, the CDO Trustees assigned litigation rights
    associated with the RMBS certificates back to Plaintiffs across all five lawsuits.
    Plaintiffs amended their complaint accordingly in the U.S. Bank Action, and in
    response, U.S. Bank included in its answer the affirmative defense of champerty,
    signaling that it intended to assert that Plaintiffs still lacked standing because the
    CDO Trustees’ assignment of litigation rights back to Plaintiffs was invalid under
    New York law. See 
    N.Y. Jud. Law § 489
     (“No person or co-partnership . . . and no
    corporation or association . . . shall solicit, buy or take an assignment of, or be in
    any manner interested in buying or taking an assignment of a bond, promissory
    note, bill of exchange, book debt, or other thing in action, or any claim or demand,
    with the intent and for the purpose of bringing an action or proceeding
    thereon[.]”).
    In 2020, after discovery was complete, the district court in the U.S. Bank
    Action granted summary judgment in favor of U.S. Bank, agreeing that the CDO
    Trustees’ assignments were champertous and, as a result, finding that Plaintiffs
    lacked both Article III and prudential standing – i.e., finding that Plaintiffs neither
    (1) suffered a concrete and particularized injury in fact, fairly traceable to the
    challenged actions of U.S. Bank and likely redressable by a favorable judicial
    6
    decision, nor (2) asserted their own legal rights and interests. See Phx. Light SF Ltd.
    v. U.S. Bank Nat’l Ass’n, 
    612 F. Supp. 3d 263
    , 277–87 (S.D.N.Y. 2020), reconsideration
    denied, No. 14-cv-10116 (VSB), 
    2020 WL 4699043
     (S.D.N.Y. Aug. 12, 2020). A year
    later, this Court affirmed on the ground that the assignments were champertous
    and that Plaintiffs thus lacked prudential standing. See Phx. Light, 
    2021 WL 4515256
    , at *1–2. In so doing, we assumed but did not decide the issue of Article
    III standing. See id. at *1.
    After we affirmed, the district court in the BNY Mellon 2014 Action – which
    had been at the summary-judgment stage before being stayed pending the appeal
    in the U.S. Bank Action – ordered the parties to brief the effect of our decision.
    That same order also directed the parties to brief the effect on a related action
    concerning BNY Mellon’s role as a master servicer of an RMBS trust (the “BNY
    Mellon 2018 Action”), which had been severed from the BNY Mellon 2014 Action
    and had been in discovery at the time of the stay. After the briefing, the district
    court issued an order dismissing both actions, which “assume[d]” that Plaintiffs
    had Article III standing, Phx. Light SF Ltd. v. Bank of N.Y. Mellon, No. 14-cv-10104
    (VEC), 
    2022 WL 92213
    , at *2 n.6 (S.D.N.Y. Jan. 7, 2022), but found that Plaintiffs
    were precluded from relitigating the issue of prudential standing by the U.S. Bank
    7
    Action, see 
    id.
     at *3–6. In the alternative, the district court found that Plaintiffs
    lacked prudential standing “under a fresh analysis.” 
    Id.
     at *5 n.15. About a month
    later, the district court in the Deutsche Bank Action, which like the BNY Mellon
    2014 Action was at the summary-judgment stage, arrived at the exact same
    conclusions. See Phx. Light SF Ltd. v. Deutsche Bank Nat'l Tr. Co., 
    585 F. Supp. 3d 540
    , 559–63 & nn.15–16 (S.D.N.Y. 2022). 1
    Plaintiffs timely appealed.
    II.   DISCUSSION
    We review a district court’s grant of summary judgment de novo. See Garcia
    v. Hartford Police Dep't, 
    706 F.3d 120
    , 126–27 (2d Cir. 2013). We also “generally
    review de novo a district court’s ruling on” issue preclusion, also known as
    collateral estoppel, because the doctrine “frequently turn[s] on pure questions of
    law, or on the application of law to undisputed facts.” Hoblock v. Albany Cnty. Bd.
    of Elections, 
    422 F.3d 77
    , 93 (2d Cir. 2005); see also United States v. U.S. Currency in
    1In its summary-judgment order dismissing the Deutsche Bank Action for lack of prudential
    standing based on issue preclusion, the district court also reached issues pertaining to the
    underlying substance of Plaintiffs’ claims – as the district court in the BNY Mellon 2014 Action
    previously had in a summary-judgment order in 2017. On appeal, Plaintiffs contend that the
    district courts erred in granting summary judgment to Deutsche Bank and BNY Mellon on some
    of these substantive issues as well, but because we affirm the dismissals based on issue preclusion
    and prudential standing, we need not reach those questions.
    8
    the Amount of $119,984.00, More or Less, 
    304 F.3d 165
    , 171–72 (2d Cir. 2002).
    Applying the de-novo review standard, we conclude that the district courts
    appropriately dismissed all three actions on appeal.
    A. Bypassing Jurisdiction
    As an initial matter, we reject Plaintiffs’ contention that the district courts
    were obliged to address whether Plaintiffs had Article III standing before
    determining that Plaintiffs lacked prudential standing. The parties strenuously
    debate whether past cases holding that courts may assume Article III standing in
    order to dismiss on prudential-standing grounds, such as Kowalski v. Tesmer, 
    543 U.S. 125
     (2004), and Hillside Metro Associates v. JPMorgan Chase Bank, 
    747 F.3d 44
    (2d Cir. 2014), are still good law in light of more recent cases, such as Lexmark
    International, Inc. v. Static Control Components, Inc., 
    572 U.S. 118
     (2014), and SM Kids,
    LLC v. Google LLC, 
    963 F.3d 206
     (2d Cir. 2020). But we need not answer that
    question today: even if we assume that the prudential-standing question at issue
    here involved a merits determination that should not have been substantively
    considered before Article III standing, the district courts were (and we are) still
    permitted to bypass Article III standing to consider whether Plaintiffs were
    collaterally estopped from relitigating the issue of prudential standing.
    9
    Despite the ordinary rule that courts must address questions pertaining to
    constitutional jurisdiction first, see, e.g., Steel Co. v. Citizens for Better Env’t, 
    523 U.S. 83
    , 93–102 (1998), the Supreme Court has supplied courts with “leeway” to dismiss
    actions based on non-jurisdictional, non-merits grounds, particularly where the
    constitutional-jurisdiction question is “difficult to determine” and dismissing on
    the threshold issue is “the less burdensome course.” Sinochem Int’l Co. v. Malay.
    Int’l Shipping Corp., 
    549 U.S. 422
    , 431, 436 (2007); see also In re Facebook, Inc., Initial
    Pub. Offering Derivative Litig., 
    797 F.3d 148
    , 155–59 (2d Cir. 2015). For example, in
    Sinochem, the Supreme Court held that a district court had discretion to dismiss
    under the doctrine of forum non conveniens before disposing of any other
    threshold challenges, including to personal or subject-matter jurisdiction. See 
    549 U.S. at
    430–36; see also, e.g., Ellis v. Dyson, 
    421 U.S. 426
    , 433–34 (1975) (holding that
    dismissals based on abstention under Younger v. Harris, 
    401 U.S. 37
     (1971), may be
    resolved before addressing jurisdiction); Tenet v. Doe, 
    544 U.S. 1
    , 6 n.4 (2005)
    (similarly holding that dismissals under Totten v. United States, 
    92 U.S. 105
     (1876),
    may be resolved before addressing jurisdiction).
    Joining the Ninth Circuit, we hold that issue preclusion, or collateral
    estoppel, is another such non-merits threshold ground that is suitable for
    10
    resolution before addressing a difficult or novel question of constitutional
    jurisdiction. See Snoqualmie, 8 F.4th at 861–63. 2 As the Ninth Circuit explained,
    issue preclusion is a non-merits inquiry because it “does not require the court to
    assume substantive law-declaring power.” Id. at 862; see also Sinochem, 
    549 U.S. at 433
     (characterizing this as “[t]he critical point”); United States ex rel. Hanks v. United
    States, 
    961 F.3d 131
    , 137 (2d Cir. 2020) (same).                         Rather, “[j]ust as a
    forum[-]non[-]conveniens dismissal is a determination that the merits should be
    adjudicated by a different court, an issue[-]preclusion dismissal is a determination
    that the merits (of at least one issue) have already been adjudicated by a different
    court.” Snoqualmie, 8 F.4th at 862 (emphasis omitted). In other words, because
    “jurisdiction is vital only if the court proposes to issue a judgment on the merits,”
    Intec USA, LLC v. Engle, 
    467 F.3d 1038
    , 1041 (7th Cir. 2006), and an issue-preclusion
    dismissal is not a judgment on the merits, courts are permitted to dismiss on the
    basis of issue preclusion without reaching harder Article III standing questions.
    2 Other courts have already so held for the related doctrine of claim preclusion. See Env't
    Conservation Org. v. City of Dallas, 
    529 F.3d 519
    , 524–25 (5th Cir. 2008) (recognizing that claim
    preclusion could be considered before the jurisdictional issue of mootness, but declining to do so
    because the facts did not present “a textbook case for immediate res judicata dismissal” (internal
    quotation marks omitted and alterations adopted)); Hoffman v. Nordic Nats., Inc., 
    837 F.3d 272
    ,
    277–78 (3d Cir. 2016) (holding that a court can assume subject-matter jurisdiction to dismiss on
    claim-preclusion grounds, because doing so does “not technically [produce] a judgment on the
    merits”); cf. also Comm’r of Internal Revenue v. Sunnen, 
    333 U.S. 591
    , 597 (1948) (noting that courts
    may dispose of cases on res judicata grounds “without reaching the merits of the controversy”).
    11
    And here, the district courts were faced with a thorny Article III standing
    question. We appreciate that “[i]n the mine run of cases, jurisdiction will involve
    no arduous inquiry.” Sinochem, 
    549 U.S. at 436
     (internal quotation marks omitted).
    But this is not a mine-run case. To the contrary, the constitutional-standing
    inquiry presents a hotly debated question. Compare, e.g., Plaintiffs Br. at 26–31
    (No. 22-239) (asserting that Article III jurisdiction is satisfied), with BNY Mellon Br.
    at 41–46 (No. 22-239) (asserting Article III jurisdiction is not satisfied), and
    Deutsche Bank Br. at 35–42 (No. 22-503) (same). As a result, we conclude that the
    district courts were permitted to dismiss on the basis of issue preclusion without
    assessing the question of constitutional jurisdiction – and that we are permitted to
    affirm on that ground, as we do now. See Hoffman, 
    837 F.3d at
    278 n.33.
    B. Issue Preclusion
    “Collateral estoppel, or issue preclusion, prevents parties or their privies
    from relitigating in a subsequent action an issue of fact or law that was fully and
    fairly litigated in a prior proceeding,” M.O.C.H.A. Soc’y, Inc. v. City of Buffalo, 
    689 F.3d 263
    , 284 (2d Cir. 2012), including issues of standing, see Mrazek v. Suffolk Cnty.
    Bd. of Elections, 
    630 F.2d 890
    , 896 n.10 (2d Cir. 1980); see also Morabito v. New York,
    
    803 F. App’x 463
    , 467 (2d Cir. 2020); Stengel v. Black, 
    486 F. App’x 181
    , 183 (2d Cir.
    12
    2012). The preclusive effect of a judgment rendered by a federal court sitting in
    diversity – as was the district court in the U.S. Bank Action – is determined by the
    law of the state in which the rendering court sat – here, New York. See Semtek Int’l
    Inc. v. Lockheed Martin Corp., 
    531 U.S. 497
    , 508 (2001). “Under New York law,
    collateral estoppel bars relitigation of an issue when (1) the identical issue
    necessarily was decided in the prior action and is decisive of the present action,
    and (2) the party to be precluded from relitigating the issue had a full and fair
    opportunity to litigate the issue in the prior action.” Plymouth Venture Partners, II,
    L.P. v. GTR Source, LLC, 
    988 F.3d 634
    , 642 (2d Cir. 2021) (internal quotation marks
    omitted); see also In re Howard v. Stature Elec., Inc., 
    20 N.Y.3d 522
    , 525 (2013).
    Applying this framework, we agree with the district courts that the prior
    determination of prudential standing in the U.S. Bank Action satisfied the
    prerequisites for issue preclusion. More specifically, the district courts correctly
    determined that the champerty-based prudential-standing issue in the BNY
    Mellon 2014, BNY Mellon 2018, and Deutsche Bank Actions was decisive and
    identical to the one decided in the U.S. Bank Action, because it was undisputed
    below and on appeal that materially identical transactions with the CDO Trustees
    were at issue in all the actions. Additionally, we cannot say that the district courts
    13
    erred in determining that Plaintiffs had a full and fair opportunity to litigate the
    champerty-based prudential-standing issue in the U.S. Bank Action. Although a
    couple of the Plaintiffs did not participate in the U.S. Bank Action, the district
    courts found that the absent parties were sufficiently in privity with parties who
    did participate, see Buechel v. Bain, 
    97 N.Y.2d 295
    , 304–05 (2001) (describing New
    York’s privity standard in issue-preclusion context) – a finding that Plaintiffs do
    not challenge on appeal, see Norton v. Sam's Club, 
    145 F.3d 114
    , 117 (2d Cir. 1998)
    (“Issues not sufficiently argued in the [appellate] briefs are considered [forfeited]
    and normally will not be addressed on appeal.”).
    Plaintiffs’ arguments to the contrary are unavailing. First, in all three
    appeals, Plaintiffs assert that the prudential-standing question decided in the U.S.
    Bank Action was a pure legal question and thus could not have issue-preclusive
    effect under New York law. See, e.g., Plymouth Venture, 988 F.3d at 642; Am. Home
    Assurance Co. v. Int’l Ins. Co., 
    90 N.Y.2d 433
    , 440 (1997) (holding that because the
    plaintiff’s arguments concerned “a pure question of law,” “the doctrine of
    collateral estoppel does not preclude [the plaintiff] from litigating that issue
    again”). But, in fact, the champerty-based prudential-standing determination in
    the U.S. Bank Action was not a purely legal one. Under New York law, “the
    14
    purpose behind the plaintiff’s acquisition of rights is the critical issue in assessing
    whether such acquisition is champertous,” Justinian Cap. SPC v. WestLB AG, 
    28 N.Y.3d 160
    , 166–67 (2016) (internal quotation marks omitted and alterations
    adopted), and “the question of intent and purpose of the purchaser or assignee of
    a claim is usually a factual one,” Bluebird Partners, L.P. v. First Fid. Bank, N.A., 
    94 N.Y.2d 726
    , 738 (2000) (internal quotation marks omitted); see also Tr. for Certificate
    Holders of Merrill Lynch Mortg. Invs., Inc. v. Love Funding Corp., 
    13 N.Y.3d 190
    , 195,
    200 (2009). Applying this case law, the district court in the U.S. Bank Action rested
    its champerty-based prudential-standing determination on factual findings
    regarding the intent and purpose behind the CDO Trustees’ assignments, see Phx.
    Light, 612 F. Supp. 3d at 281–86, as did we when affirming, see Phx. Light, 
    2021 WL 4515256
    , at *1–2 (“Based on the factual findings of the [d]istrict [c]ourt, it is clear
    that the assignments made were indeed champertous[.]”). As such, New York’s
    pure-legal-question exception to issue preclusion has no application here. See Am.
    Home Assurance, 
    90 N.Y.2d at
    440 n.1 (noting that “mixed question[s] of law and
    fact” are subject to issue preclusion).
    Second, Plaintiffs assert that fairness and other equitable considerations
    should have barred the application of issue preclusion in the BNY Mellon 2018
    15
    Action and the Deutsche Bank Action. We disagree. For starters, Plaintiffs
    forfeited these arguments in the BNY Mellon 2018 Action by failing to raise them
    to the district court, and we decline to exercise our discretion to consider them
    now for the first time on appeal. See Doe v. Trump Corp., 
    6 F.4th 400
    , 409–11 (2d
    Cir. 2021).
    As to the Deutsche Bank Action, we recognize that under New York law,
    “the question of fairness . . . in the application of the doctrine [of issue preclusion]
    must be the crowning consideration.” Read v. Sacco, 
    375 N.Y.S.2d 371
    , 375 (2d
    Dep’t 1975). Indeed, as an extension of the requirement that the party to be
    precluded from relitigating had a full and fair opportunity to litigate the issue in
    the prior action, “each case must be examined to determine whether, under all the
    circumstances, the party said to be estopped was not unfairly or prejudicially
    treated in the litigation in which the judgment sought to be enforced was
    rendered.” 
    Id.
     But instead of offering ways in which Plaintiffs were unfairly treated
    in the U.S. Bank Action, Plaintiffs only suggest that it is generally unfair to invalidate
    their assignments, as they had pursued those assignments based on the reasonable
    assumption that ratification under Federal Rule of Civil Procedure 17(a)(3) was
    unavailable. To the extent this is even a cognizable complaint within New York’s
    16
    issue-preclusion rubric, Plaintiffs’ strategic miscalculations do not generate
    unfairness; even prior to Fund Liquidation Holdings LLC v. Bank of America Corp.,
    attempting ratification would not have been directly contrary to controlling
    precedent in this Circuit. See 
    991 F.3d 370
    , 387 (2d Cir. 2021) (recognizing the issue
    as “an open question”); FDIC v. Citibank N.A., No. 15-cv-6574 (ALC), 
    2017 U.S. Dist. LEXIS 108104
    , at *8–9 (S.D.N.Y. July 10, 2017) (allowing parties to ratify to
    cure standing defects prior to Fund Liquidation).
    Relatedly, Plaintiffs suggest that Deutsche Bank should have been
    prevented from invoking the equitable doctrine of issue preclusion because it had
    unclean hands. See PenneCom B.V. v. Merrill Lynch & Co., 
    372 F.3d 488
    , 493 (2d Cir.
    2004) (“New York courts have long applied the maxim that one ‘who comes to
    equity must come with clean hands.’” (quoting Amarant v. D’Antonio, 
    602 N.Y.S.2d 837
    , 838 (1st Dep’t 1993))). Granted, in its capacity as a CDO Trustee, Deutsche
    Bank Trust Company Americas was a party to one of the champertous
    assignments. This, however, does not render Deutsche Bank’s hands unclean – or
    the application of issue preclusion unfair – as it is undisputed that Plaintiffs were
    the ones who orchestrated the assignments. See 
    id.
     (explaining that “one who has
    17
    acted fraudulently, or who by deceit or any unfair means has gained an
    advantage,” cannot invoke preclusion (internal quotation marks omitted)).
    Third, and finally, Plaintiffs assert that they should not have been precluded
    from relitigating prudential standing in the BNY Mellon 2014 Action because in
    that action BNY Mellon had neglected to plead, and thus waived, champerty as an
    affirmative defense. See J. App’x at 707–11 (No. 22-239) (district court recognizing
    the waiver). However, regardless of what BNY Mellon pleaded, the district court
    was permitted to consider the affirmative defense of issue preclusion – even issue
    preclusion of champerty-based prudential standing – in accordance with the
    “strong public policy in economizing the use of judicial resources by avoiding
    relitigation.” Curry v. City of Syracuse, 
    316 F.3d 324
    , 330–31 (2d Cir. 2003) (internal
    quotation marks omitted) (holding that a court may, in its discretion, permit an
    issue-preclusion defense to be raised for the first time on summary judgment); see
    also Doe v. Pfrommer, 
    148 F.3d 73
    , 80 (2d Cir. 1998) (“Although the district court
    raised the issue of collateral estoppel sua sponte, this decision does not require
    reversal.”).
    The New York case law Plaintiffs cite is not to the contrary. Although New
    York courts have commented that “the dismissal of a complaint as against one
    18
    party need not be given res judicata effect as against another . . . when the
    dismissal was based upon a defense that was personal to that party,” Raab v.
    Kaleida Health, 
    875 N.Y.S.2d 411
    , 412 (4th Dep’t 2009), the champerty-based
    prudential-standing defense was not personal to U.S. Bank. Rather, putting aside
    the pleading defect, the defense was equally available to BNY Mellon, given that
    Plaintiffs had executed virtually identical agreements with the relevant CDO
    Trustees in both the BNY Mellon 2014 and U.S. Bank Actions. Thus, the fact that
    BNY Mellon did not assert the champerty defense in its answer did not prevent
    the district court from exercising its discretion to consider the defense as part of its
    issue-preclusion and prudential-standing analysis, particularly since Plaintiffs had
    ample notice of BNY Mellon’s issue-preclusion arguments and an opportunity to
    respond. See Curry, 
    316 F.3d at 331
    . 3
    In short, we fully agree with the district courts that Plaintiffs were not
    entitled to a second bite at the prudential-standing apple after the U.S. Bank
    Action. The district courts therefore did not err in taking this straightforward, if
    not “textbook,” path to dismissal. Sinochem, 
    549 U.S. at 435
    .
    3Equally meritless is Plaintiffs’ related contention that the issue-preclusion dismissal in the BNY
    Mellon 2018 Action was improper because no formal summary-judgment motion was filed. The
    district court did not need to abide by the strictures of Federal Rule of Civil Procedure 56 to
    dismiss for issue preclusion. See Pfrommer, 
    148 F.3d at 80
    ; Hoffman, 
    837 F.3d at 280
    .

    III.   CONCLUSION
    For the reasons stated above, we AFFIRM the judgments of the district
    courts.
