Questão jurídica principal
Whether the federal appeal could only challenge constitutional defects in the cantonal cassation decision, not the merits of federal civil law
Decisão extraída
The appeal was limited to constitutional review of the cassation decision; complaints attacking federal civil law were not the object of review.
Fundamentação extraída
The cassation court could only examine specified Nichtigkeitsgründe and not the substantive application of federal civil law, which the Federal Supreme Court would review directly only against the proper target decision.
