Questione giuridica chiave
Whether contribution liability for a basis-erosion road could be imposed case-by-case when the perimeter plan was opened.
Decisione estratta
The contribution duty for basis-erosion facilities must be established at ordinance level; it cannot be created only in the individual perimeter-plan procedure. However, the road at issue was not a basis-erosion facility.
Motivazione estratta
Section 8 lit. b KER requires a municipal regulation to introduce such liability. Yet the Bannstrasse served direct access and was therefore not a basis-erosion facility within that provision.
