Key legal question
Whether the constitutional complaint was admissible despite non-exhaustion of cantonal remedies
Extracted holding
The complaint was inadmissible because the complainants had not used the available cantonal nullity appeal against the Obergericht's refusal to set aside the discontinuation decision.
Extracted reasoning
The challenged decision was not a final cantonal decision within the meaning of Art. 86 OG, since a cantonal nullity appeal remained available for the alleged arbitrary fact-finding and evidentiary assessment.
