Questione giuridica chiave
Whether the federal appeal was admissible against the cantonal decision on the criminal investigation, hearing rights, and costs
Decisione estratta
The appeal was admissible only to the extent it challenged the reviewable issues decided by the cantonal authority; purely appellatory criticism and matters outside the contested decision were inadmissible.
Motivazione estratta
The decision was an independently opened interlocutory criminal procedural ruling. Only sufficiently substantiated grievances against the appealable decision could be heard; complaints about matters not forming part of the decision, or about general investigation conduct, were outside the scope.
