Municipal Illegality Claims in Chile

What this involves

Chile's municipalities, governed by Ley 18.695 (Ley Orgánica Constitucional de Municipalidades), make decisions that affect foreign investors and property owners every day: business licenses (patentes), alcohol licenses, closures, fines, abandoned-property declarations and refusals of permits. When a mayor or a municipal official acts illegally, or fails to act when the law requires it, the law offers a reclamo de ilegalidad, which is regulated in article 151 of that statute.

The claim has two stages. It starts before the mayor and, if the mayor rejects it or does not answer, continues before the Corte de Apelaciones. Courts regularly reject claims that skip the first stage, so the order of steps matters as much as the arguments.

The deadlines in plain terms

Under the law, the claim is first presented to the mayor within 30 days of the publication of the act or, for omissions, of the request. The mayor has 15 days to resolve, and silence counts as rejection. The claim to the Corte de Apelaciones must then be filed within 15 days of the rejection or of the end of the mayor's period. These periods are short and strict. Special regimes apply to some building-department decisions, which follow the Ley General de Urbanismo y Construcciones, so we confirm the correct route from the start.

What we handle

What the court can do

The Corte de Apelaciones reviews the legality of the act. It does not substitute its own policy judgment. If the claim succeeds, the court can annul the act in whole or in part, order the municipality to correct an omission or issue a new decision, and send the file to the prosecutor if there are signs of a crime. The court can also suspend the act while it decides if its execution would cause irreparable harm. After a ruling that declares the illegality, the affected person can sue for damages in the ordinary courts, and the illegality cannot be reopened in that case.

A scenario we see: the owner abroad

A frequent case involves an owner living abroad whose property is declared abandoned, or a foreign entrepreneur who opens a restaurant or short-term rental and receives a closure order. The municipality notified a local address, the deadline passed and the owner heard late. We check how and when the act became known, because the time limit can depend on publication or notification, and we use that to protect rights. Where a deadline has been missed, other routes, such as a recurso de protección or a Contraloría request, may still apply.
