Questione giuridica chiave
Whether the cantonal decision on provisional maintenance under Art. 137 CC could be reviewed only for constitutional violations
Decisione estratta
Yes. Because the order concerned provisional measures, only constitutional rights could be invoked and the Federal Tribunal was bound by the facts unless a constitutional violation affecting the result was shown.
Motivazione estratta
Art. 98 LTF restricts review of provisional-measure decisions to constitutional complaints; factual findings may be corrected only if the appellant specifically demonstrates constitutional error and decisive impact.
