Questão jurídica principal
Whether the president of the criminal chamber's letter constituted an appealable decision on jurisdiction under Art. 92 BGG.
Decisão extraída
The letter was not an individually binding decision in the pending criminal case, but only a response to an abstract legal question; therefore there was no appealable object.
Fundamentação extraída
No real jurisdictional dispute under the cantonal procedure was shown. The criminal investigator had merely asked for interpretation of Art. 3(2) JStG. Because the response did not resolve a concrete dispute between the parties and no hearing of the other participants occurred, it could not be treated as a decision under Art. 92 BGG.
