Whether the appeal against the cantonal cassation judgment was admissible although the decision was incidental.
Decisão extraída
The challenged decision was incidental and did not cause irreparable prejudice or justify immediate review to avoid a long and costly evidentiary procedure.
Fundamentação extraída
Under Art. 93 para. 1 and Art. 117 LTF, incidental decisions are only appealable if they meet those conditions; neither condition was satisfied here.
