Kernrechtsfrage
Whether the special PPA zone should be treated as a building zone under spatial-planning law.
Extrahierter Entscheid
No. The special zone was not a building zone; it remained a non-building zone governed by the federal separation principle.
Extrahierte Begründung
The isolated equestrian complex did not meet Art. 15 LAT criteria for a building zone. A special zone under cantonal law does not become constructible merely because it is not agricultural; competence and zone qualification are determined by federal law.
