Questão jurídica principal
Whether the federal complaint was admissible despite the lower court's non-entry finding on standing.
Decisão extraída
The appellants were sufficiently affected by the cantonal decision and had a protected interest in its annulment; the complaint was admissible to that extent.
Fundamentação extraída
The cantonal judgment upheld the refusal to enter into the merits and thus confirmed the validity of the withdrawal in the cantonal proceedings, which directly affected the appellants' procedural position.
