Kernrechtsfrage
Whether the constitutional complaint could challenge the alleged violation of the right to judicial review of a release request.
Extrahierter Entscheid
The complaint was inadmissible on this point because the alleged federal-law issues had to be raised by appeal, not by subsidiary constitutional complaint.
Extrahierte Begründung
Art. 31(4) BV and Art. 5(4) ECHR are concretized by the federal Civil Code provisions on commitment review; their alleged breach concerns federal law and therefore falls within appeal, making the constitutional complaint subsidiary.
