Key legal question
Whether the federal appeal against the refusal of pretrial sentence execution remained live
Extracted holding
The appeal had become moot because the competent district judge would decide the pretrial execution request in separate cantonal proceedings and that decision would replace the prosecutor's refusal.
Extracted reasoning
The subject matter of the complaint was already pending before the competent cantonal judge; the federal proceedings therefore had to be discontinued as moot under the procedural rules on mootness and discontinuance.
