Questão jurídica principal
Whether the federal complaint could challenge alleged arbitrary fact-finding without exhausting the cantonal nullity appeal
Decisão extraída
Those factual grievances were inadmissible because they could have been raised before the Zurich Cassation Court.
Fundamentação extraída
A federal civil appeal requires exhaustion of cantonal remedies; claims of manifestly incorrect fact-finding belonged to the available cantonal nullity complaint.
