Questione giuridica chiave
Whether the connection fee base may include a functionally separate, non-connected building part.
Decisione estratta
Including the non-connected hall and storage part in the fee base violated the equivalence principle because the municipality provided no corresponding service and the non-connected part clearly outweighed the connected part.
Motivazione estratta
The hall and storage had no municipal water or sewer connection, no relevant municipal effort was required, and the non-connected part was substantially larger than the connected part; the usual fee level was clearly exceeded.
