Questione giuridica chiave
Whether advance invoices for connection fees are appealable before final taxation.
Decisione estratta
Yes. The advance invoices are interim decisions with potentially significant adverse effects and are therefore appealable.
Motivazione estratta
Although the fees become due upon connection, the invoices were issued before final SGV valuation and required payment within 30 days. Their temporary but burdensome effect makes them equivalent to interim decisions under § 66 VRG.
