Question juridique clé
Whether the constitutional complaint was admissible against a cantonal civil judgment where federal civil-law issues were open to appeal
Solution extraite
No; the complaints concerned issues of federal civil law reviewable by ordinary appeal, so the constitutional complaint could not be used to raise them.
Motifs extraits
The challenged arguments attacked the burden of proof and evidentiary standard under federal civil law, which cannot be examined by constitutional complaint when appeal is available.
