How to Stop Extradition from Mexico: Grounds for Refusal, Appeals and Deadlines

This page focuses on refusal grounds, evidence, deadlines and remedies. For the sequence from the foreign request to the SRE decision, see Extradition from Mexico: the procedure and decision-makers.

Which Mexican authority can stop extradition?

Under articles 22–23 of the Ley de Extradición Internacional (International Extradition Law, LEI), the District Court in the jurisdiction where the person is found handles the judicial stage, and its acts in that proceeding are not subject to an ordinary appeal. If the person's whereabouts are unknown, article 22 refers to the criminal District Court on duty in the former Federal District, now Mexico City; counsel should verify the current assignment. The judge issues a legal opinion, but does not make the final grant. Under articles 29–30, the SRE decides. Article 33 says a final grant is challengeable only through amparo.

The Supreme Court's First Chamber explained in Amparo en Revisión 1125/2015 (22 February 2017) that, once a timely amparo is filed, the SRE must await its final resolution and any review proceedings before physically surrendering the person. Identify the exact act at issue: the final SRE agreement, a provisional-arrest request, or another procedural act can trigger different arguments and suspension rules.

Which refusal grounds should the defence prove?

Read the applicable extradition treaty together with the LEI. Article 1 describes the LEI as the framework where no treaty exists; article 2 applies its procedure to requests received from foreign governments. A treaty may add or modify requirements. Check the text, current status, reservations or declarations, and whether both states are bound. Mexico is not part of the European Arrest Warrant system.

These are not interchangeable tests. Articles 7–9 state express refusal rules; article 10 Bis addresses a defined risk of torture or disappearance; article 10 requires undertakings within its terms. A treaty may supply additional grounds. General allegations of unfairness do not prove every statutory element.

Does Mexican nationality prevent extradition?

No. LEI article 14 allows delivery of a Mexican national in exceptional cases at the Executive's discretion; article 15 says nationality acquired after the conduct does not prevent delivery. The applicable treaty matters too. The SRE lists the Mexico–United States Extradition Treaty of 4 May 1978 and its 1997 amending protocol as in force. Article 9 of the Mexico–United States treaty concerns provisional arrest, not nationality. Apply LEI articles 14–15 and check the actual treaty provisions relevant to the request; do not treat article 9 as a nationality rule. Nationality is relevant, but not an automatic bar.

Under LEI article 11, delivery is generally deferred until final release if the person has a separate pending Mexican case or sentence and extradition otherwise proceeds. That is postponement, not necessarily refusal. Article 12 sets priority criteria where more than one state requests the same person.

Which deadlines and triggers matter?

Do not calculate from arrest alone. Obtain stamped orders, the record of the first appearance, the complete SRE agreement and proof of notification. The treaty may alter a period, and the amparo deadline must be calculated under the procedural rules that apply to the specific act.

For amparo, articles 18–19 generally start the count on the day after legally effective notice and exclude Saturdays, Sundays and specified non-working days. Do not assume this automatically resolves the SRE's separate 15-day wording in LEI article 33; have counsel calculate both issues from the actual record.

What can amparo and suspension achieve?

An indirect amparo is a separate constitutional case before the competent federal amparo District Court. It is not an ordinary appeal and not a retrial of guilt. Grounds may concern the legal basis, reasoning, treaty compliance, constitutional rights or whether the authorities applied the relevant statutory conditions. In Amparo en Revisión 828/2005 (6 April 2006), the Supreme Court's Plenary described extradition as administrative in nature despite its judicial stages. The defence should identify a concrete legal defect rather than rely only on a general claim of innocence.

Suspension is separate from the merits. In binding jurisprudence from Contradicción de Criterios 44/2022 (6 November 2024), the Supreme Court's First Chamber held that when an amparo challenging extradition is admitted, the judge must order suspension de plano y de oficio (immediately and on the court's own initiative) to prevent physical delivery until the amparo is finally resolved, and must open a suspension incident for other related acts. This protection does not apply where a ground for dismissing the claim is apparent.

The distinction between acts matters. If the challenged act is the extradition order itself, the physical handover must be stopped after admission of the amparo. If the case concerns only a provisional-arrest request or its processing, the court must address suspension through the separate incident under article 127 rather than automatically treating that request as the final extradition order under article 126. Neither route guarantees release from custody or success on the merits. The official Supreme Court materials checked for this pass did not reveal a later decision expressly overruling the 2024 jurisprudence.

What documents should the defence assemble?

LEI article 16 requires core material in the formal request, including the offence, supporting evidence or an authenticated final judgment, the relevant foreign offence and penalty provisions, limitation rules, an arrest warrant where relevant, and identifying information. Foreign-language documents must be translated into Spanish and legalised as the statute requires. Ask for the complete court and SRE files, all service records, the applicable treaty, certified foreign procedural dates, identity records and the original documents supporting any risk claim. A minor translation defect is not automatically fatal; connect the defect to a material requirement or real prejudice.

How do political persecution, asylum and torture risks affect the case?

For LEI article 8, connect the request to political persecution with individual evidence, not only a public profile or a general allegation of bias. A useful file may include a timeline of political activity, threats, statements by officials, comparable cases and evidence of selective prosecution.

The Ley sobre Refugiados, Protección Complementaria y Asilo Político (Refugees, Complementary Protection and Political Asylum Law) codifies non-refoulement in article 6. It prohibits rejecting or returning an applicant or refugee to a country where the relevant persecution grounds or a well-founded risk of torture or cruel, inhuman or degrading treatment exists; it also protects recipients of complementary protection from return to the specified danger. A refugee application is distinct from an LEI challenge and should not be assumed to suspend extradition automatically. Tell counsel about any pending protection claim or recognised status and coordinate the evidence so that statements are consistent.

Mexico is not a party to the European Convention on Human Rights, so ECtHR Rule 39 is not a route against Mexico. Mexico recognised the UN Committee against Torture's competence to receive individual communications under article 22 of the Convention against Torture on 15 March 2002. If there is a credible torture risk, counsel may assess a communication and request interim measures, subject to admissibility rules, including domestic-remedy exhaustion and restrictions on parallel examination. This is not an automatic Mexican court stay and must not replace an urgent amparo.

Is an INTERPOL notice enough to extradite someone?

No. A Red Notice or diffusion is not itself the SRE's final extradition decision. Establish whether the person faces a Mexican detention order, provisional request, formal request, final SRE agreement or a different immigration measure. A separate request to the Commission for the Control of INTERPOL's Files (CCF) may challenge data that appear unlawful or inaccurate, but it does not replace amparo and does not automatically stop extradition. The CCF requires a properly submitted, signed and documented request under its current rules. Since 26 March 2026, requests must be submitted through INTERPOL's dedicated secure online portal. See how to check an INTERPOL Red Notice. If officials call the measure deportation, removal or transfer, obtain the written act because the authority and deadlines may differ; see extradition versus deportation.

Which mistakes weaken a challenge?

• Relying on Mexican nationality alone without applying LEI article 14 and the treaty.
• Arguing innocence as if the extradition judge were conducting the foreign criminal trial.
• Missing the three-day exception period or waiting for an expert report before preserving an objection.
• Assuming asylum, a CCF request, a UN communication or a diplomatic letter automatically stops delivery.
• Using general country reports without connecting them to the person's likely treatment, authority or facility.
• Confusing consent to extradition with waiver of a hearing. Under LEI article 28, no exceptions or express consent can lead to an opinion within 3 days; consent should be informed and advised.
• Assuming the 30-day amparo wording removes the delivery risk created by LEI article 33's 15-day wording.

A practical decision path for a person or family

1. After detention: obtain the order and provisional or formal request, arrange counsel and an interpreter if needed, record the date and time, and preserve the article 25 exceptions deadline.
2. Before the SRE decision: identify the exact act that may be challenged. If provisional measures were used, check the treaty and the two-month article 18 clock. A detention challenge does not automatically decide the final extradition question.
3. After an SRE grant: obtain the complete signed agreement and proof of notification; prepare amparo immediately and ask for suspension against physical delivery. Do not wait while the 15/30-day issue is being analysed.
4. After an adverse amparo ruling: ask whether review is available and protect the 10-day period in article 86. Confirm the proper Tribunal Colegiado de Circuito or the limited Supreme Court route.
5. If torture or persecution is the main risk: assemble individual evidence for the domestic challenge and separately assess refugee protection or an admissible UN communication. Do not assume an international request alone stops transfer.

Hypothetical example: a person detained in Mexico on a United States request says the limitation period has expired and the receiving authorities may impose a prohibited punishment. Counsel should obtain the SRE and court files, compare both countries' limitation laws, identify the exact charge and available sentence, check the current bilateral treaty, and request any required undertaking. The defence must also preserve the article 25 evidence period. If the SRE grants extradition, counsel should file amparo immediately and seek suspension against physical delivery.
