Questione giuridica chiave
Whether the public law appeal was admissible against a cantonal remand decision.
Decisione estratta
No; the challenged decision was incidental and caused no irreparable harm, and the exception for simultaneous nullity appeal did not apply because that appeal was itself inadmissible.
Motivazione estratta
A remand decision is not final. Under Art. 87(2) OJ, public law review of an incidental decision requires irreparable harm. The special exception for parallel nullity appeals presupposes that the nullity appeal is admissible; here the cantonal court had not finally decided federal-law issues.
