Key legal question
Whether the appellants had standing to challenge parliamentary and governmental acts concerning the initiative
Extracted holding
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.
Extracted reasoning
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.
