Question juridique clé
Whether the appellants had standing to challenge parliamentary and governmental acts concerning the initiative
Solution extraite
Only Giuliano Bignasca could potentially challenge measures affecting the initiative process he initiated; Attilio Bignasca and the parliamentary group lacked standing for acts from procedures in which they had not participated.
Motifs extraits
The contested acts concerned direct participation in prior proceedings and, for the other appellants, there was no participation or legally protected position under political-rights review.
