Kernrechtsfrage
Whether the complaint alleging denial of hearing was admissible despite an available cantonal remedy
Extrahierter Entscheid
The hearing-right complaints were inadmissible because the cantonal nullity remedy under Bern procedure had not been exhausted.
Extrahierte Begründung
A state-law complaint lies only after cantonal remedies are exhausted; the alleged refusal of evidence, failure to address invoices, and inadequate reasoning could have been raised by the cantonal nullity appeal.
