collateral order doctrine in Pennsylvania

2026Melvin v. Doe, 836 A.2d 42, 46-47 (Pa. 2003) (citations omitted). -3- J-A26020-25 the Supreme Court rejected the Chiluttis’ argument that, “because they may incur a substantial loss of money in litigating this action in arbitration, the trial court’s order compelling arbitration meets the requirements of the third prong of the collateral order doctrine.” See id. at 833-834.

2025“As an exception to the rule of finality, the doctrine is to be interpreted narrowly, and ‘each prong of the collateral order doctrine must be clearly present before an order may be considered collateral.’” Vaccone v. Syken, 899 A.2d 1103, 1106 (Pa. 2006) (superseded on other grounds by Pa. R.A.P. 1114(b)(7)) (quoting Melvin v. Doe, 836 A.2d 42, 47 (Pa. 2003)).

2026As to the first prong of the collateral order test, our Supreme Court has explained that “[a]n order is separable from the main cause of action if it can be resolved without an analysis of the merits of the underlying dispute and if it is entirely distinct from the underlying issue in the case.” Shearer v. Hafer, 177 A.3d 850, 858 (Pa. 2018) (emphasis added).

2026Furthermore, our Supreme Court has cautioned that we temper our -5- J-A30003-25 application of the collateral order doctrine, mindful “that a party may seek an interlocutory appeal by permission pursuant to Pa.R.A.P. 312.” Shearer v. Hafer, 177 A.3d 850, 858 (Pa. 2018) (footnote and citation omitted).

2026As Chief Justice Todd has made abundantly clear, we are to “construe the collateral order doctrine narrowly . . . to avoid piecemeal determinations and the consequent protraction of litigation.” Rae v. Pennsylvania Funeral Directors Association, 977 A.2d 1121 , 1129 (Pa. 2009) (quoting Sullivan v. Philadelphia, 107 A.2d 854, 855 (Pa. 1954)).

2025Rae v. Pennsylvania Funeral Directors Association, 977 A.2d 1121 , 1126 (Pa. 2009). 4 With regard to the first prong of the collateral order test, “if the resolution of an issue concerning a challenged [decision] can be achieved independent from an analysis of the merits of the underlying dispute, then the order is separable” from the main cause of action.

2023As a means to reinforce and support the final order rule, however, this Court has concluded that the collateral order doctrine must be narrowly construed, and, before application thereof, “every one of its three prongs [must] be clearly present,” especially considering that a party may seek permission to appeal an interlocutory—i.e., non-final—order pursuant to Pennsylvania Rule of Appellate Procedure 312, Pa.R.A.P. 312. 3 Rae, 977 A.2d at 1126 (citing Melvin v. Doe, 836 A.2d 42, 47 (Pa. 2003), and Geniviva v. Frisk, 725 A.2d 1209 , 1214 & n.5 (Pa. 1999)); Shearer, 177 A.3d at 858 . 3 Pennsylv

2022See In re Barnes Foundation, 871 A.2d 792, 794 (Pa. 2005) (“Pennsylvania law does allow for an appeal as of right from an order denying intervention in circumstances that meet the requirements of the collateral order doctrine.”); Geniviva v. Frisk, 725 A.2d 1209, 1214 (Pa. 1999) (explaining that, for a right to be too important to be denied review for purposes of the collateral order doctrine, the right must be “deeply rooted in public policy going beyond the particular litigation at hand”).

2024In Ben, our Supreme Court determined that an order compelling an agency to produce its investigative files pertaining to complaints filed against a dentist was appealable under the collateral order exception to a final order. 729 A.2d at 552 .

2022To determine whether an issue is sufficiently important to support application of the collateral order doctrine, “[a court should] weigh the interests implicated in the case against the costs of piecemeal litigation.” Id. “[I]t is not sufficient that the issue be important to the particular parties.

2026We acknowledge that this Court is to construe “the collateral order doctrine narrowly so as to avoid undue corrosion of the final order rule and to prevent delay resulting from piecemeal review of trial court decisions.” K.C. v. L.A., 128 A.3d 774, 778 (Pa. 2015) (citations and quotation marks omitted).

2025K.C., supra at 777 (“Otherwise known as the collateral order doctrine, Rule 313(b) provides that an interlocutory order is collateral and, therefore, immediately appealable, if . . . .”).

2026In so doing, the High Court distinguished the facts of that case from the facts involved in Pridgen v. Parker Hannifin Corp., 905 A.2d 422, 427 (Pa. 2006), adhered to on reargument, 916 A.2d 619 (Pa. 2007), which we discuss infra, and expressly rejected the proposition that the potential expenditure of substantial litigation expenses is sufficient to meet the third prong of the collateral order doctrine.

2026That statutory procedure, however, is not available in common law arbitration proceedings because Section 7321.24 is not listed in Section 7342(a) as a provision of the Revised Statutory Arbitration Act that is applicable to common law arbitration. [J-59-2025] - 10 In an attempt to avoid this result, the Chiluttis rely on this Court’s decision in Pridgen v. Parker Hannifin Corporation, 905 A.2d 422 (Pa. 2006), for the proposition that a party’s potential “substantial loss” of money in litigating a claim is sufficient to meet the third prong of the collateral order doctrine.9 They submit that,

2025“Absent the satisfaction of all three prongs of the collateral order test, this Court has no jurisdiction to consider an appeal of an otherwise non-final -5- J-S07001-25 order.” Spanier v. Freeh, 95 A.3d 342, 345 (Pa. Super. 2014) (citation omitted).

2024The collateral-order rule is “a specialized, practical application of the general rule that only final orders are appealable as of right.” Spanier v. Freeh, 95 A.3d 342, 345 (Pa. Super. 2014).

2025To invoke the collateral order doctrine, each of the three prongs identified in the rule’s definition must be clearly satisfied. -6- J-A21029-24 In re W.H., 25 A.3d 330, 335 (Pa. Super. 2011) (some citations omitted and formatting altered).

2014After Commonwealth v. Harris, 612 Pa. 576 , 32 A.3d 243 (2011), I had thought that orders requiring disclosure over and against the assertion of a privilege would be appealable as of right, without the necessity of episodic review of each of the requirements of the collateral order doctrine.

2020To invoke the collateral order doctrine, each of the three prongs identified in the rule’s definition must be clearly satisfied.” J.M., 219 A.3d at 655 (quoting In re W.H., 25 A.3d 330, 335 (Pa. Super. 2011)). -7- J-S20001-20 Specifically, as to the first prong, we have stated: [A]n order is separable from the main cause of action if it is entirely distinct from the underlying issue in the case and if it can be resolved without an analysis of the merits of the underlying dispute.

2023Therefore, they have not satisfied the third prong of the collateral order test. -8- J-E01003-23 In its discussion of the collateral order doctrine, the Majority quotes our Supreme Court’s decision in Commonwealth v. Wells, 719 A.2d 729 (Pa. 1998), in which the Court recognized that Rule 313 “sets forth a narrow exception to the general rule that only final orders are subject to appellate review.” Majority Opinion at 7 (quoting Wells, 719 A.2d at 730).

2022However, directing Appellant, a limited partnership, to disclose this specific information is distinguishable from the facts presented in the cases cited above, which directed particular individuals to provide, broadly, years of tax returns and other documents showing their entire “financial worth.” See Cooper, 905 A.2d at 485 ; Cabot Oil, 241 A.3d at 1197 ; Merithew, 869 A.2d at 1042 ; J.S., 860 A.2d at 1117 . - 13 - J-A03038-22 Accordingly, we conclude Appellant has not established the second prong of the collateral order doctrine — that the underlying discovery order “involves a right too i

2020“The collateral order doctrine is an exception to the general rule that all appeals must await final judgment.” Id. at 362 (emphasis omitted). “[W]hether an order is appealable as a collateral order under Rule 313 is [therefore] an issue of [the] Court’s jurisdiction to entertain an appeal of such an order.” Commonwealth v. Kennedy, 876 A.2d 939, 943 (Pa. 2005); see also Shearer 7 The Family Court contends that “[a]lthough the trial [c]ourt has now certified this matter for [] immediate appeal, the appealability of the . . .

2022With respect to the first prong of the collateral order doctrine, an order is separable from the main cause of action “if it can be resolved without an analysis of the merits of the underlying dispute.” Commonwealth v. Williams, . . . 86 A.3d 771, 781 ([Pa.] 2014).

2021Ass’n, 977 A.2d 1121 , 1125 (Pa. 2009); see also id. at 1123, 1129 (explaining that the collateral order doctrine is narrowly construed, and adopting an issue-by-issue approach to its application); Commonwealth v. Williams, 86 A.3d 771, 780 (Pa. 2014) (stating that “the collateral order doctrine is to be narrowly construed in order to buttress the final order doctrine”).

2017Under the collateral order doctrine as set forth in Pennsylvania Rule of Appellate Procedure 313, “an order is immediately appealable if (1) it is separable from and collateral to the main cause of action; (2) the right involved is too important to be denied review; and (3) the question presented is such that if review is postponed until final judgment in the case, the claimed right will be irreparably lost.” In re N.B., 817 A.2d 530, 534 (Pa. Super. 2003) (citing Pugar v. Greco, 483 Pa. 68 , 394 A.2d 542, 545 (1978)) (footnote omitted); see Pa.R.A.P. 313.

Johnson, . . . 705 A.2d 830, 834 (Pa. 1998), the Court adopted the reasoning of Flanagan v. United States, 465 U.S. 259 . . . (1984), and held that a pretrial order removing trial counsel in a criminal case does not satisfy the collateral order exception, and thus, is not immediately appealable.

2021Rule 313 codified the three-part collateral order doctrine first formulated by the United States Supreme Court in Cohen, as an exception to the final order rule in cases where lower courts’ decisions do not terminate the case, yet “finally determine claims of right separable from, and collateral to, rights asserted in the action, too important to be denied review and too independent of the cause itself to require that appellate consideration be deferred until the whole case is adjudicated.” Cohen, 337 U.S. at 546 ; see also Shearer, 177 A.3d at 855-58 (tracing the evolution of the collateral o

2020However, in Cohen v. Beneficial Industrial Loan Corporation, 337 U.S. 541, 546 (1949), our United States Supreme Court, acknowledging the harshness of the final order rule in certain situations, explicitly recognized an exception to the rule through the collateral order doctrine, which permitted the appeal of a narrow class of orders which address claims of right “separable from, and collateral to, rights asserted in the action, too important to be denied review and too independent of the cause [of action] itself to require that appellate consideration be deferred until the whole case is adjud

2018The collateral order doctrine provides that “an interlocutory order is appealable if (1) it is separable from and collateral to the main cause of action; (2) the right involved is too important to be denied review; and (3) the question presented is such that if review is postponed until final judgment in the case, the claimed right will be irreparably lost.” Id. 1114 (citing In re J.S.C., 851 A.2d 189, 191 (Pa. Super. 2004)).
