Questione giuridica chiave
Whether the federal nullity appeal was admissible against the cantonal decision on territorial jurisdiction.
Decisione estratta
The nullity appeal was inadmissible because the same cantonal decision could be challenged by reform appeal under the OG.
Motivazione estratta
The attacked ruling was an incidental decision on territorial jurisdiction in a civil pecuniary case exceeding the monetary threshold; therefore reform appeal was available, which excludes nullity under Art. 68 OG.
