Questão jurídica principal
Whether the public-law appeal was admissible despite the lack of cantonal nullity appeal
Decisão extraída
The public-law appeal was admissible because the complaint concerned arbitrariness in fact-finding and evidence assessment, not a violation of essential procedural rules.
Fundamentação extraída
The other cantonal remedy was unavailable for the claims raised, so the exhaustion requirement was satisfied and the Federal Tribunal entered into the merits.
