Key legal question
Whether the prosecutor still had a current practical legal interest in challenging the release from detention
Extracted holding
No current practical interest remained because the respondent had already been released and the prosecutor could seek coercive measures again if circumstances changed.
Extracted reasoning
Federal review requires a current practical interest; the contested detention decision had already been fully executed, and the prosecutor had not sought suspensive effect. The exceptions to the current-interest requirement were not shown and, in any event, the issue had become moot in light of the pending loss of relevance of cantonal procedure after the new federal code.
