Key legal question
Whether the civil complaint against the cantonal decision was admissible and what could be challenged.
Extracted holding
The complaint was admissible as to the Obergericht judgment, but not as to the first-instance order; the case concerned a final decision and a constitutional-review-limited provisional measure.
Extracted reasoning
Only the cantonal appellate judgment is the object of challenge under Art. 90 BGG. Provisional registration is a protective interim measure under Art. 98 BGG, so only constitutional rights may be invoked and arguments must be properly substantiated.
