Key legal question
Whether the public-law appeal was admissible despite the availability of a cantonal nullity complaint.
Extracted holding
The appeal was admissible because the complaint concerned arbitrariness in fact-finding and evidence assessment, not a violation of essential procedural rules.
Extracted reasoning
Such complaints fall within public-law review; a nullity complaint was not open on the grounds invoked, and the requirement of exhaustion of cantonal remedies was satisfied.
