Key legal question
Whether the civil-law appeal on costs in a precautionary-measures case was admissible and reviewable only for constitutional violations.
Extracted holding
The appeal could be examined only insofar as constitutional rights were properly invoked and substantiated; other complaints were inadmissible.
Extracted reasoning
Because the case concerned precautionary measures, federal review was limited by Art. 98 BGG. The court also treated the cantonal decision on costs as a final decision, but applied strict substantiation requirements under Art. 106(2) BGG.
