Kernrechtsfrage
Whether the complaint alleging denial of the right to be heard was admissible without first raising a cantonal nullity complaint.
Extrahierter Entscheid
The hearing-right complaint was inadmissible because it could have been raised before the cantonal appellate plenary by nullity complaint, and the cantonal remedies were not exhausted.
Extrahierte Begründung
A constitutional complaint lies only after exhaustion of all cantonal remedies. A denial-of-hearing claim was available under the Bernese nullity complaint procedure, so direct federal review was barred.
