Key legal question
Whether the public-law appeal against the cantonal ruling suspending planning approval was admissible under Art. 87 OG despite being incidental.
Extracted holding
The appeal was inadmissible because the challenged ruling was an incidental decision and no irreparable legal harm was shown.
Extracted reasoning
Continuation of the approval procedure, possible need for a later ordinary revision, and increased delay or cost do not amount to irreparable prejudice; hypothetical procedural disadvantages and planning-stability considerations are insufficient.
