Questione giuridica chiave
Whether the federal civil appeal was admissible against the cantonal ruling declaring the immediate appeal inadmissible
Decisione estratta
The federal appeal was admissible, but only as an appeal against an incidental decision under Art. 93 LTF; the constitutional complaint was excluded.
Motivazione estratta
The cantonal decision did not end the accounting action. It was an incidental decision, and a legal prejudice was recognized because the question whether the immediate cantonal appeal should have been admitted could no longer be reviewed with the final judgment.
