Key legal question
Whether the constitutional complaint was admissible despite the availability of a cantonal nullity complaint
Extracted holding
No. The complaint was inadmissible because the alleged violations of arbitrariness and due process could have been raised in the cantonal nullity complaint, so the cantonal remedies were not exhausted.
Extracted reasoning
A federal constitutional complaint lies only against final cantonal decisions. Where the complained-of violations were cognizable in a cantonal remedy already used by the complainant, federal review is barred for lack of exhaustion.
