Key legal question
Whether the cantonal court could refuse to consider the recusal request because it was not translated into French.
Extracted holding
Yes. In Jura criminal proceedings, French is the procedural language; the court had no duty to accept a German filing and properly set a deadline for translation.
Extracted reasoning
The language rule under cantonal and federal law limits the freedom of language in dealings with cantonal authorities. To avoid excessive formalism, a party must be given time to provide a translation, which was done here.
