Key legal question
Whether the complaint against the prison disciplinary sanction was admissible before the Federal Supreme Court.
Extracted holding
The complaint was inadmissible because the challenged decision was based on cantonal execution law and the filing did not adequately invoke or substantiate any violation of constitutional rights.
Extracted reasoning
A criminal-law complaint may challenge detention/execution decisions, but when only cantonal law is applied, review is limited to constitutional rights. Such a claim must be expressly raised and reasoned under Art. 106(2) BGG. The filing contained only general assertions and contradictory factual statements, so the requirements were not met.
