Questione giuridica chiave
Whether the heritage association had standing to challenge the building permit decision in the cantonal proceedings.
Decisione estratta
The association had no substantive standing; it could only complain about denial of procedural participation rights, not ask the Federal Court to decide the merits.
Motivazione estratta
Under Art. 89 BGG, ideational heritage interests do not create a protected interest in the merits. Standing may exist only for procedural-rights complaints where the association had party status below. The lower court's refusal of standing was not arbitrary because the building was not inventoried and the quarter-preservation zone was not a heritage-protection measure under the relevant cantonal scheme.
