Questão jurídica principal
Whether Art. 24 RPG applied because the previous special zoning order had become void after demolition of the hotel
Decisão extraída
The special planning order remained formally valid; demolition did not make it void, and the area remained subject to a planning duty rather than Art. 24 RPG.
Fundamentação extraída
Defects in a planning act are generally only voidable. Demolition of the hotel created at most changed circumstances; such substantive changes require formal plan amendment or withdrawal of approval, not a finding of nullity.
