Questão jurídica principal
Whether the municipal initiative was inadmissible because it conflicted with federal and cantonal competence rules or was unworkable.
Decisão extraída
The initiative was not unlawful or unworkable; it merely instructed the city to seek a policy reversal from canton and Confederation, without binding those authorities.
Fundamentação extraída
The tunnel project had local traffic-planning significance and the city could legitimately ask for reconsideration. The initiative did not obstruct federal procedures or the municipal duty to pursue the project if the higher-level authorities refused to amend the network decision.
