Questão jurídica principal
Whether the public law appeal was admissible against the cantonal decision ordering document production under Art. 170 CC.
Decisão extraída
No. The complaint concerned the application of federal civil law and therefore had to be brought by reform appeal, not by public law appeal.
Fundamentação extraída
Because the dispute was a civil case governed by federal substantive law and the challenged arguments related to the correct application of Art. 170 CC, the subsidiary public law appeal was excluded.
