Whether the Pennsylvania Supreme Court's remand order was sufficiently final for Supreme Court review under 28 U.S.C. § 1257.
Holding
Yes. The Court had jurisdiction because the federal issue had been finally decided and could evade later review regardless of what occurred on remand.
Reasoning
Although state-court judgments ordinarily are not reviewable while substantive proceedings remain, this case fit the pragmatic finality exception recognized in Cox Broadcasting Corp. v. Cohn. The Pennsylvania Supreme Court had conclusively decided that defense counsel was constitutionally entitled to inspect the confidential file, while only further merits proceedings remained.
If the trial court found the withheld material immaterial or the error harmless, Ritchie's conviction would be reinstated and the Commonwealth could not seek review of an issue on which it had prevailed. If Ritchie received a new trial, an acquittal would bar Commonwealth review under double jeopardy, while a conviction would leave review dependent on Ritchie's choice to appeal. Immediate review was therefore warranted to prevent the confidentiality issue from becoming effectively unreviewable.
