Questão jurídica principal
Whether the appeal against the cantonal decision annulling the trial summons was admissible as an incidental decision.
Decisão extraída
The decision was incidental and did not meet the requirements for immediate federal review; no irreparable legal harm or case-ending effect was shown.
Fundamentação extraída
The challenged ruling concerned only the validity of trial summonses. Any issue could be raised later against the final cantonal judgment; the alleged prejudice was hypothetical and not irreparable within Art. 93 LTF.
