•Urban Planning and Environmental Law
The Council for Permit Disputes (RvVb) annulled, on 9 October 2025, a financial charge imposed in a decision granting an environmental permit. Such a charge may, since 2024, only be imposed on the basis of an urban planning regulation within the meaning of Articles 2.3.1 and 2.3.2 of the Flemish Code for Spatial Planning (VCRO). Prior to the amendment of the Decree, the Environmental Permit Decree did provide that such a financial charge could be imposed by the permitting authority and under what conditions, but it was not required that a regulation be included in an urban planning ordinance.
