Question juridique clé
Whether the updated fire-safety certificate justified reconsideration and revocation of the building permit.
Solution extraite
The updated fire-safety certificate did not show a relevant change of circumstances or a conflict with applicable law sufficient to reopen and revoke the permit.
Motifs extraits
The cantonal court reasonably relied on the fire expert who stated that removing the eastern openings would not reduce fire safety, while the applicants' expert remained too general and did not identify concrete non-compliance.
