Amparo before the Constitutional Court protects fundamental rights when ordinary remedies failed to fix a serious breach. It does not replace cassation or reopen facts out of disappointment. We often see amparo filed late or without exhausting prior routes. This analysis covers requirements, deadlines and coordination with other remedies.
Purpose of amparo
It protects constitutionally recognised rights and developed case law: effective judicial protection, presumption of innocence, expression, among others.
Identify a concrete act or ruling causing the breach.
The Constitutional Court is not a fourth criminal or civil instance.
Admission is selective; the brief must be precise on fact, law and relief.
Exhaustion of prior remedies
As a rule, ordinary routes must be finished: cassation, review or equivalent.
Amparo while appeals pend may be inadmitted.
In criminal matters, cassation then amparo is the usual sequence when constitutional grounds exist.
Poor calendar planning closes amparo on formal grounds.
Deadlines
The general period is short from notification of the final ordinary ruling.
Specific counting and extension rules apply in limited cases.
Bring exact notification dates to the first consultation.
Relation to cassation
Cassation pursues uniform law; amparo pursues fundamental-rights injury.
Sometimes constitutional points should be flagged already in cassation.
Sometimes neither route is viable—we say so clearly.
One partner owns overall strategy across remedies.
Documents to assess viability
Final rulings, admission or inadmission orders, notification dates.
Key briefs where breaches were already raised.
One-page procedural timeline.
We then judge whether amparo is useful or wasted cost.
