Question juridique clé
Whether the request for an interpreter made at the start of trial was time-barred under cantonal procedure.
Solution extraite
The cantonal court could treat the request as late because the accused knew the proceedings would be conducted in German and had not sought interpreter assistance within the prescribed period.
Motifs extraits
The language of the proceedings was fixed by cantonal law; the summons indicated the deadline; prior French-language questioning did not justify a good-faith expectation of French trial debates.
