Key legal question
Whether the direct constitutional complaint against a cantonal statute was admissible before the Federal Supreme Court.
Extracted holding
The complaint was inadmissible because Grisons law provides for a cantonal judicial norm review, so federal review lies only against the cantonal court's norm-control decision.
Extracted reasoning
Under Art. 87 BGG, direct federal appeal against cantonal enactments is excluded when cantonal law provides a remedy; the appellants had to exhaust the cantonal review before the Administrative Court acting as constitutional court.
