Questione giuridica chiave
Whether a direct appeal to the Federal Supreme Court against the cantonal first-instance definitive debt-recovery order was admissible without first appealing to the cantonal higher court.
Decisione estratta
The appeal was inadmissible because the cantonal instance chain was not exhausted; the first-instance decision had to be challenged before the Zurich Higher Court first.
Motivazione estratta
Under Zurich procedure, first-instance debt-recovery decisions must first be appealed to the Higher Court. Federal review is possible only after the cantonal remedies are used, especially for grounds not reviewed by the Higher Court or reviewed with narrower cognition.
