Questão jurídica principal
Whether advance invoices for connection fees are appealable before final taxation.
Decisão extraída
Yes. The advance invoices are interim decisions with potentially significant adverse effects and are therefore appealable.
Fundamentação extraída
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.
