Questão jurídica principal
Whether the constitutional complaint was admissible despite the availability of a cantonal nullity appeal
Decisão extraída
The constitutional complaint was inadmissible because the cantonal remedies were not exhausted; the impugned judgment was not a final cantonal decision.
Fundamentação extraída
A constitutional complaint requires exhaustion of cantonal remedies. Since a cantonal nullity appeal to the Zurich Court of Cassation was available and was in fact filed, the Zurich Court of Appeal judgment was not the last cantonal instance.
