Key legal question
Whether the absolute and unconditional obligation for taxi operators with parking permits to affiliate with an approved dispatch central is proportionate and constitutionally lawful.
Extracted holding
The obligation is neither suitable nor necessary to ensure a permanent canton-wide dispatch system; it is unconstitutional because it mainly serves to secure the survival of smaller dispatch centers and therefore amounts to prohibited economic-policy favoritism.
Extracted reasoning
Large dispatch centers already attract enough affiliated drivers without compulsion, so the measure is not needed to secure the public-interest service. To the extent it merely protects weaker competitors, it pursues economic-policy goals rather than a permissible public-interest restriction.
