Questione giuridica chiave
Whether the appeal against the cantonal remittal decision was admissible before the Federal Supreme Court.
Decisione estratta
The remittal ruling was an interlocutory decision and did not cause irreparable harm; the conditions for immediate appeal were not met.
Motivazione estratta
The municipality must still decide again on the modified project, and any objections can be raised later against a final cantonal decision. Mere delay or added costs are insufficient; a later appeal under Art. 93(3) BGG remains available.
