Key legal question
Whether the federal appeal was admissible despite being labeled a constitutional complaint and lacking a separate substantive request
Extracted holding
The appeal was admissible as a public law appeal; the prayer for annulment was sufficient in this context.
Extracted reasoning
The Court applied the BGG transitional and admissibility rules, held that the return order was an appealable interlocutory decision, and accepted standing for both the municipality and the neighboring owner.
