The Amparo proceeding is the most powerful tool in the Mexican legal system for protecting rights against unlawful acts of government authority. But its effectiveness depends on filing it correctly and on time.
When Does Administrative Amparo Apply?
Administrative amparo applies against acts by administrative authorities (federal, state, or municipal) that violate fundamental rights or individual guarantees. The most common scenarios include: excessive fines, unfounded business closures, denial of licenses or permits, tax inspections without a legal order, and expropriations without adequate compensation.
Deadlines: The Most Critical Factor
The general deadline to file an amparo is 15 business days from the date the affected party became aware of the act. Exceptions include:
- Amparo against laws: 30 days from their entry into force or first act of application
- Acts affecting agrarian rights: no statute of limitations applies
- Acts depriving liberty: may be filed at any time
A single day of delay can render the amparo inadmissible. There is no second chance.
Suspension of the Challenged Act
One of the most important advantages of amparo is the ability to request a provisional suspension of the challenged act, which may be granted on the same day the petition is filed. This can, for example, stop the closure of a business while the merits of the case are resolved.
Strategy: What to Do Before Filing the Petition
Before filing an amparo, it is essential to exhaust all available ordinary remedies (tax review appeals, administrative complaints, etc.), unless urgency prevents this. Filing a premature amparo without exhausting prior remedies may result in dismissal for failure to meet the definitiveness requirement.
