Question juridique clé
Whether Winterthur could invoke municipal autonomy against the annulment of its location compensation scheme.
Solution extraite
Winterthur had protected autonomy in financing and fee-setting for its waste incineration plant, so it was entitled to complain of an infringement.
Motifs extraits
Cantonal law left the municipality a relatively wide discretion in organizing and financing the plant and in setting charges; thus autonomy existed in this field.
