Kernrechtsfrage
Whether the formally final building permit for the pig stable had to be revoked under § 22 VRG.
Extrahierter Entscheid
Yes. The permit was formally final but materially unlawful, and the balance of interests favoured restoring legality.
Extrahierte Begründung
The earlier permit failed to address the environmental law issue. Because the minimum distances to the residential zone were clearly and substantially undershot, a particularly weighty public interest in correct application of the law justified revocation despite legal certainty and good-faith reliance by the builder.
