Key legal question
Whether the appeal was admissible despite limited cantonal remedies and unraised constitutional complaints.
Extracted holding
The civil appeal was admissible only for federal-law issues; complaints that should have been raised by cantonal nullity appeal, especially on hearing rights and arbitrary evidence assessment, were not examined.
Extracted reasoning
The Federal Supreme Court may freely review federal civil law, making the cantonal nullity appeal unavailable on those points. Constitutional and evidentiary complaints were therefore unexhausted or insufficiently reasoned.
