Question juridique clé
Whether the constitutional complaint was admissible despite available cantonal nullity proceedings on the hearing-compliance complaint.
Solution extraite
The hearing-violation complaint had to be raised first in cantonal nullity proceedings; direct review by the Federal Supreme Court was unavailable.
Motifs extraits
The Bernese Appellationshof judgments were subject to nullity proceedings before the plenary court, which allowed a complaint for denial of hearing but not for arbitrary assessment of evidence. The cantonal remedies were therefore not exhausted.
