Key legal question
Whether the absence of the full bill from the voting materials violated political rights and justified annulling the vote.
Extracted holding
The omission made the information insufficient, but it was not serious enough to have decisively affected the clear result of the referendum.
Extracted reasoning
Cantonal law did not require mailing the full text, yet the complexity and importance of the bill made broader disclosure desirable. Because voters also received an explanatory message summarizing the bill and both sides' arguments, the remaining deficit was minor and could not realistically have changed the outcome.
