Key legal question
Whether the public-law appeal could be used to complain about alleged violations of federal criminal law and whether the due-hearing claim was sufficiently substantiated.
Extracted holding
The public-law appeal could not be used to raise federal-law complaints, and the due-hearing argument was rejected as unfounded or inadmissible.
Extracted reasoning
The Court held that public-law review is limited to constitutional grievances; the appellant did not show arbitrariness in the refusal of further psychiatric evidence, and the complaint about lack of counsel during investigation had not been exhausted before the cantonal instance.
