Key legal question
Whether the appeal against the interim-measures decision was admissible under the Federal Supreme Court Act
Extracted holding
Only constitutional rights could be invoked against the challenged interim-measures decision, but the appellant did not raise any admissible constitutional grievance and failed to meet the substantiation requirements.
Extracted reasoning
The decision concerned interim measures under Art. 137 CC, so Art. 98 BGG limited review to constitutional violations. The submission neither invoked constitutional rights nor explained, with sufficient precision, how the cantonal reasoning violated them. A later supplementation after expiry of the appeal period was barred.
