Questione giuridica chiave
Whether the appeal against the Zurich High Court decision was admissible without exhausting the cantonal cassation remedy
Decisione estratta
The appeal against the High Court decision was inadmissible because the cantonal cassation remedy had to be exhausted first.
Motivazione estratta
In protective-measures matters only constitutional rights could be raised; the Zurich cassation complaint allowed review of all federally admissible grievances, so Art. 75 BGG required exhaustion of that remedy.
