Kernrechtsfrage
Whether objections that the conditions for a quarter-plan amendment were not met were admissible at this stage
Extrahierter Entscheid
The objection was too late because it had to be raised against the opening decision; the opening decision was final.
Extrahierte Begründung
Art. 16(2) KRVO/GR requires objections to the planning procedure and perimeter to be raised in the opening decision phase. Since appellants did not do so, the argument could no longer be heard after the plan had been drafted.
