Post-Sentence SORNA II (Subchapter I) Constitutional Challenges Are Civil Actions Against PSP in Commonwealth Court—Not PCRA or Habeas in Common Pleas

1. Introduction

Commonwealth, Aplt. v. Arnett (Pa. Mar. 26, 2026) reached the Supreme Court of Pennsylvania after the York County Court of Common Pleas held that Subchapter I of SORNA II, 42 Pa. C.S. §§ 9799.51–.75, was unconstitutional as applied to Robert W. Arnett—an individual convicted of sexual offenses in 2004 and subject to lifetime registration.

Arnett filed a pro se petition fifteen years after his judgment of sentence, styling it under the Post Conviction Relief Act (PCRA), 42 Pa. C.S. §§ 9541–9546. Appointed counsel later filed an “Amended PCRA Petition/Motion for Writ of Habeas Corpus.” The Common Pleas Court granted relief by concluding Subchapter I was unconstitutional and effectively enjoining enforcement of Arnett’s registration obligations with the Pennsylvania State Police (PSP), the registry’s administrator. The Commonwealth appealed.

Justice Brobson’s opinion is concurring and dissenting: he agrees with the Majority’s threshold holding that the PCRA is not a proper vehicle to attack Subchapter I registration requirements, but he dissents from the Majority’s reaching the merits (and reversing under Commonwealth v. Torsilieri, 316 A.3d 77 (Pa. 2024)) because, in his view, the Common Pleas Court lacked subject matter jurisdiction to adjudicate Subchapter I’s constitutionality at all.

2. Summary of the Opinion (Justice Brobson)

  • Agreement with the Majority: The PCRA is not a viable mechanism to challenge Subchapter I registration requirements.
  • Core disagreement: Because the PCRA was unavailable (and habeas, in his view, also unavailable), the Common Pleas Court had no subject matter jurisdiction to rule on Subchapter I’s constitutionality; therefore, the Supreme Court should not reach that constitutional question either.
  • Proper forum and framing: A post-sentence attempt to end SORNA II registration is best understood as a civil action against PSP—thus falling within the Commonwealth Court’s exclusive original jurisdiction under 42 Pa. C.S. § 761(a)(1), (b).
  • Proposed disposition: Vacate the Common Pleas Court’s merits determination and direct that relief, if any, must be pursued through a proper mechanism in the proper court (Commonwealth Court), rather than issuing what he characterizes as an advisory merits ruling.

3. Analysis

3.1. Precedents Cited

A. Jurisdiction is a threshold requirement; appellate courts must address it first

Justice Brobson grounds his approach in a line of cases treating subject matter jurisdiction as the “indispensable foundation” of adjudication:

  • In re J.M.Y., 218 A.3d 404, 415 (Pa. 2019): the Court “will not consider the merits” if the lower court lacked jurisdiction; and when a lower court proceeded to merits without addressing jurisdiction, the Supreme Court has a “duty” to determine jurisdiction before deciding appellate issues.
  • In re Petition of Acchione, 227 A.2d 816 (Pa. 1967) (cited via In re J.M.Y.): supports the proposition that a reviewing court must confirm jurisdiction when it is in doubt.
  • M & P Mgmt., L.P. v. Williams, 937 A.2d 398, 402 (Pa. 2007): finality cannot be supplied to a judgment entered without subject matter jurisdiction.
  • In re Admin. Ord. No. 1-MD-2003, 936 A.2d 1, 5–6 (Pa. 2007): jurisdiction is “fundamental”; it cannot be conferred by consent and cannot be waived.

These authorities do the heavy lifting for his structural claim: even if parties agree the trial court had jurisdiction (and even if adversarial briefing is imperfect), the Supreme Court must resolve jurisdiction before addressing constitutionality.

B. Habeas corpus: “custody” and the limits of using habeas for SORNA registration

Justice Brobson recognizes the doctrinal path that could support habeas jurisdiction—namely, that “custody” can extend beyond incarceration—but argues the path does not reach SORNA registration:

  • Commonwealth ex rel. Paylor v. Claudy, 77 A.2d 350, 352 (Pa. 1951): courts of common pleas (as well as the Supreme Court and Superior Court) have habeas jurisdiction, establishing that if habeas were proper, common pleas could hear it.
  • Commonwealth ex rel. Stevens v. Myers, 213 A.2d 613, 623 (Pa. 1965): habeas tests the legality of a “sentence being served,” framing habeas as sentence-focused.
  • Commonwealth ex rel. Paulinski v. Isaac, 397 A.2d 760, 763 (Pa. 1979): habeas requires “custody,” but custody can include non-incarcerative restraints not shared by the public generally.
  • Commonwealth v. Hess, 414 A.2d 1043, 1046–47 (Pa. 1980): bail restraints can satisfy custody.
  • Commonwealth ex rel. Ensor v. Cummings, 215 A.2d 651, 652 (Pa. 1966): parole status can satisfy custody.

He then contrasts SORNA registration with traditional sentence-linked restraints. Although he acknowledges Commonwealth v. Lacombe, 234 A.3d 602 (Pa. 2020), describing Subchapter I as “akin to probation” (Lacombe, 234 A.3d at 623), and notes Commonwealth v. Vivian, 231 A.2d 301, 305 (Pa. 1967), calling probation a restriction on freedom, he emphasizes that probation is still a criminal sentence.

  • Commonwealth v. Fiore, 491 A.2d 276, 280 (Pa. Super. 1985): “probation” is a sentence under the Sentencing Code.

Because (as the Majority noted) Subchapter I is not criminal punishment, Justice Brobson remains “unconvinced” that habeas is available where the registrant is not serving a sentence and not facing imminent incarceration. That conclusion is pivotal: if habeas does not fit, the Common Pleas Court has no jurisdictional foothold once the PCRA is off the table.

C. Proper forum: Commonwealth Court exclusive original jurisdiction for civil actions against the Commonwealth

Justice Brobson’s proposed jurisdictional “home” for post-sentence constitutional challenges is the Commonwealth Court, relying on:

  • 42 Pa. C.S. § 761(a)(1), (b): Commonwealth Court has exclusive original jurisdiction over “all civil actions or proceedings” against the Commonwealth government, with exceptions he views as inapplicable.
  • 42 Pa. C.S. § 9799.67: PSP maintains the registry, reinforcing that the practical target of an action seeking removal/exemption from registration is PSP.
  • Commonwealth v. Lacombe, 234 A.3d 602, 644 (Pa. 2020) (Wecht, J., concurring and dissenting): Justice Wecht’s presumption that a registrant seeking removal could pursue relief in Commonwealth Court; Justice Brobson endorses this direction.

He also uses the statutory structure of SORNA II to rebut the Majority’s “no funneling” point: when the General Assembly intended filing in the sentencing court, it said so expressly.

  • 42 Pa. C.S. § 9799.59(a)(2): provides an explicit petition mechanism in the sentencing court for certain exemptions; Justice Brobson treats this as evidence that broader post-sentence constitutional challenges were not similarly assigned to common pleas.

D. Avoiding advisory constitutional adjudication

Justice Brobson characterizes the Majority’s merits ruling (beyond the PCRA holding) as “merely advisory” if the lower court lacked jurisdiction. He invokes:

  • In re Leopardi, 532 A.2d 311, 315 (Pa. 1987): even if an outcome seems inevitable, it is “less important than an improper exercise of powers not given.”

E. The merits backdrop the Majority reached (but Justice Brobson would not)

The Majority (as summarized by Justice Brobson) relied on Commonwealth v. Torsilieri, 316 A.3d 77 (Pa. 2024), to hold that the Common Pleas Court erred in finding Subchapter I unconstitutional. Justice Brobson does not analyze Torsilieri’s substance; his point is institutional: merits cannot be reached absent jurisdiction.

3.2. Legal Reasoning

Justice Brobson’s reasoning proceeds in a strict sequence:

  1. PCRA is unavailable for Subchapter I challenges (a point he shares with the Majority). Therefore, the Common Pleas Court’s PCRA jurisdiction under 42 Pa. C.S. § 9545(a) cannot support the order.
  2. If the petition is recharacterized as habeas, jurisdiction would be possible in common pleas (per Commonwealth ex rel. Paylor v. Claudy)—but only if habeas is substantively proper.
  3. Habeas is not substantively proper here because, in his view, habeas is tethered to custody in the criminal-case sense (sentence being served; imminent incarceration; bail/parole-type restraints), and SORNA Subchapter I obligations—while burdensome and “akin to probation” in some respects—are not a criminal sentence and are not punishment.
  4. Once both PCRA and habeas fail as vehicles, the claim becomes what it functionally is: a post-sentence effort to end registration administered by PSP. That is a civil action “against the Commonwealth government,” placing it in the Commonwealth Court’s exclusive original jurisdiction under 42 Pa. C.S. § 761(a)(1), (b).
  5. Because the Common Pleas Court lacked subject matter jurisdiction, the Supreme Court should vacate and decline merits review, instead of endorsing a merits reversal that rests on a jurisdictionally defective foundation.

Embedded in this reasoning is a separation-of-powers and institutional-competence theme: jurisdictional limits are not technicalities; they define the judiciary’s lawful power to declare statutes unconstitutional in a given proceeding.

3.3. Impact

If Justice Brobson’s approach were adopted as controlling law in a future majority opinion, it would meaningfully reshape post-sentence SORNA litigation in Pennsylvania:

  • Forum selection would change: Registrants who have completed their sentences and seek relief from Subchapter I duties would be directed away from sentencing courts (and away from PCRA practice) and toward Commonwealth Court original jurisdiction actions against PSP.
  • Procedural discipline would increase: Appellate courts would be pressed to resolve subject matter jurisdiction before addressing SORNA constitutionality, reducing the risk of merits rulings later attacked as advisory or void.
  • Habeas boundaries would sharpen: His skepticism signals a narrower view of “custody” when the restraint is regulatory and post-sentence, even if burdens resemble probation.
  • Administrative-law framing may grow: Treating registration challenges as civil actions against PSP may import Commonwealth Court norms (e.g., pleading against an agency, record development, and remedial forms tailored to public-law litigation), potentially changing how evidence and constitutional claims are built.

Practically, his approach may cause initial delay (dismissal/transfer/refiling), but he treats that as preferable to courts exceeding jurisdiction and issuing nonbinding constitutional pronouncements.

4. Complex Concepts Simplified

Subject matter jurisdiction
A court’s legal power to decide a particular type of dispute. If a court lacks subject matter jurisdiction, its decision is void regardless of whether the parties want that court to decide the case.
PCRA
Pennsylvania’s statutory, post-conviction framework for challenging criminal convictions/sentences. It is limited to the categories of relief the statute authorizes; if a claim falls outside the PCRA, the PCRA court cannot decide it under PCRA jurisdiction.
Habeas corpus and “custody”
A traditional mechanism to challenge unlawful restraint. “Custody” can extend beyond jail (e.g., bail, parole), but Justice Brobson argues it still must resemble restraint tied to a criminal sentence or imminent incarceration—conditions he believes SORNA Subchapter I does not satisfy post-sentence.
SORNA II Subchapter I
The statutory scheme governing registration/reporting for certain offenders. Even when its obligations are onerous, Pennsylvania decisions described in this opinion treat them as nonpunitive regulatory requirements (not a criminal sentence).
Exclusive original jurisdiction (Commonwealth Court)
Certain cases must start in a specific court. Under 42 Pa. C.S. § 761, civil actions against the Commonwealth government generally must begin in Commonwealth Court, not in the courts of common pleas.

5. Conclusion

Justice Brobson’s concurring and dissenting opinion in Commonwealth, Aplt. v. Arnett advances a jurisdiction-first rule for post-sentence SORNA litigation: once the PCRA is deemed unavailable, and absent a proper basis for habeas corpus, a sentencing court in common pleas lacks subject matter jurisdiction to declare Subchapter I unconstitutional or to enjoin PSP’s enforcement of registration duties. In his view, such claims should proceed as civil actions against PSP in the Commonwealth Court’s exclusive original jurisdiction.

The opinion’s broader significance is institutional: constitutional adjudication must be anchored in a procedurally and jurisdictionally proper case, or else even a substantively correct merits result risks becoming nonbinding—an advisory disposition rendered “without powers given.”
