Key legal question
Whether the federal appeal was admissible against a cantonal remand decision in formal expropriation proceedings.
Extracted holding
The appeal was not immediately admissible because the cantonal judgment was an incidental remand decision and the appellants showed neither irreparable harm nor the conditions for immediate final review.
Extracted reasoning
The lower authority retained full discretion on the amount of any indemnity. The appellants could challenge the new decision later, and procedural prolongation or extra costs did not suffice under Art. 93 LTF.
