Question juridique clé
Whether the public-law appeal against the building permit remained justiciable after the project was withdrawn
Solution extraite
The appeal had become moot and was struck off the roll; the challenged cantonal judgment and the permit decision were also moot.
Motifs extraits
Once the permit application was withdrawn, there was no longer any live dispute. In such a situation, the Federal Supreme Court removes the case from the docket and decides costs summarily.
