Key legal question
Whether the federal appeal against the remand judgment was admissible.
Extracted holding
The appeal was admissible because the cantonal remand order could cause irreparable prejudice to the municipality, and the residents could rely on the same procedural posture.
Extracted reasoning
A remand judgment is incident; however, under the case law a municipality cannot be forced to comply with an allegedly unlawful instruction and later challenge its own decision, so the residents' parallel appeal was also admissible.
