Questione giuridica chiave
Whether the federal appeal was admissible directly against the cantonal convocation order and whether the appellants were entitled to appeal.
Decisione estratta
The appeal was admissible against the convocation order, but the requested annulment of the still-unadopted statutes was premature; the appellants had standing as active cantonal voters.
Motivazione estratta
A preparatory act such as a convocation may be attacked when it allegedly violates voting rights. Cantonal law provided no cantonal appeal against such orders, and the statutes were not yet final normative acts.
