Key legal question
Whether the federal complaint was admissible despite the lower court's non-entry finding on standing.
Extracted holding
The appellants were sufficiently affected by the cantonal decision and had a protected interest in its annulment; the complaint was admissible to that extent.
Extracted reasoning
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.
