What the court held
Justice Wecht's opinion held that the PCRA is not available to challenge SORNA II. Because both subchapters have been held non-punitive, registration is not part of a conviction or sentence, and the PCRA's purpose and eligibility terms in 42 Pa.C.S. § 9543 reach only collateral attacks on a conviction or sentence, not collateral consequences. Most registrants would also be time-barred under § 9545(b)(1). The Court declined to say which other vehicle is proper, treated the petition's alternative habeas label as preserving that route, and on the merits held that Commonwealth v. Torsilieri controls: the irrebuttable-presumption challenge fails for Subchapter I as it did for Subchapter H.
Why it matters. Registrants cannot use PCRA petitions to attack SORNA obligations and must plead a non-PCRA vehicle such as habeas corpus, coram nobis, or an action against the State Police, with the Court expressly reserving which is correct. The holding depends on SORNA II remaining non-punitive.
Separate opinions
Justice Brobson concurred and dissented, agreeing the PCRA is unavailable but arguing the Court should also have held habeas unavailable and identified mandamus in the Commonwealth Court as the proper vehicle.
