Questione giuridica chiave
Whether the public-law appeal was admissible against the provisional maintenance order
Decisione estratta
The appeal was inadmissible because the challenged decision was a cantonal last-instance provisional measure and the appellant failed to meet the applicable exhaustion and timeliness requirements only in part; the decisive problem was inadequate constitutional motivation.
Motivazione estratta
Provisional measures under Art. 137 CC are not final for a reform appeal but may be challenged by public-law appeal. However, complaints must have been raised before the last cantonal instance where possible, and the constitutional grievance must be specifically and sufficiently reasoned under Art. 90 al. 1 let. b OJ.
