Questão jurídica principal
Whether the federal appeal against the cantonal norm was admissible and timely.
Decisão extraída
The appeal was admissible: direct federal review was available, the individual appellants had standing, and the filing deadline was met.
Fundamentação extraída
Cantonal review was unavailable in Geneva for this normative act; the 30-day period ran from promulgation publication, and the appellants could be affected by the norm.
