Question juridique clé
Whether the appeal was admissible despite the possibility of a cantonal nullity complaint on some issues
Solution extraite
Review was limited to federal-law issues; challenges to factual findings and cantonal procedure were inadmissible insofar as they were not last-instance matters.
Motifs extraits
Where cantonal nullity review was still available, the Federal Supreme Court could not hear complaints about arbitrariness, hearing rights, or cantonal procedural rules; it could review federal civil law freely.
