The six participating justices on the Pennsylvania Supreme Court actually agreed on something when they determined that sexual assault as defined under the Uniform Code of Military Justice is comparable to sexual assault as defined under the Pennsylvania Crimes Code. The appellant was convicted of sexual assault under 10 U.S.C. § 920(b)(3)(A) in a general court-martial during his time in the Navy. After being discharged from the service, he moved to Pennsylvania, where the Pennsylvania State Police notified him that he was a Tier III registrant under the Sexual Offender Registration and Notification Act (“SORNA”). After litigation at the administrative level, the Commonwealth Court reversed the State Police’s categorization. But a unanimous Supreme Court reversed and reinstated the Tier III status.
