Question juridique clé
Whether advance invoices for connection fees are appealable before final taxation.
Solution extraite
Yes. The advance invoices are interim decisions with potentially significant adverse effects and are therefore appealable.
Motifs extraits
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.
