Questão jurídica principal
Whether the neighbors had standing to complain that a zoning plan was required for the project
Decisão extraída
They did not show a legally protected interest because no rule required adoption of a plan in these circumstances.
Fundamentação extraída
The cited federal and cantonal planning provisions did not impose a duty to adopt an affectation plan for development within the building zone, so the neighbors could not rely on them as protective norms under art. 88 OJ.
