Questão jurídica principal
Whether the municipal administrative appeal remained live after the taxpayer withdrew the objections.
Decisão extraída
The appeal had become moot because the taxpayer withdrew the objections, leaving the municipality unable to obtain any greater practical relief.
Fundamentação extraída
The withdrawal of the objections removed the municipality's current legal interest; even a favorable ruling would only confirm the original ex officio assessment, which was already to be treated as final in the renewed objection decision.
