Extradition from Portugal: How the Procedure Works and What an Extradition Lawyer Does

Which legal route applies to a request made to Portugal?

The first task is to identify the instrument actually being used. A foreign arrest warrant, an INTERPOL Red Notice, a formal extradition request and an EAW are not interchangeable. A Red Notice is an international police alert; it is not itself a Portuguese court judgment authorising surrender. Portuguese police may arrest a person on official foreign information in circumstances covered by Article 39 of Law No. 144/99, but the legal basis, supporting documents and next steps still have to be checked.

Law No. 144/99 is the core domestic framework for traditional extradition. It operates alongside international instruments and reciprocity rules; it is not safe to assume that the same treaty or deadline applies to every requesting state. The European Convention on Extradition remains relevant in relations where a special surrender regime has not replaced it. The United Kingdom is not covered by the EAW after Brexit; requests between Portugal and the UK may instead fall under Part Three, Title VII of the EU–UK Trade and Cooperation Agreement. A separate surrender agreement applies to relations between EU Member States and Iceland/Norway. These are not simply interchangeable labels: identify the instrument before calculating a deadline or choosing a remedy. Portugal’s official treaty record lists Portugal’s reservations under Articles 1, 2, 6, 11 and 21: no extradition for trial or sentence by a special court; no extradition where essential fair-trial guarantees or humane detention are not assured; no extradition for an offence punishable by life imprisonment; a treaty threshold requiring an offence punishable by more than one year of imprisonment; a reservation against extraditing Portuguese nationals under that Convention; no extradition for an offence punishable by death in the requesting state; and transit only where the circumstances would permit extradition. The nationality reservation under this Convention must be read alongside the Constitution, Law No. 144/99 and any separate EU or treaty surrender regime, not treated as a universal rule for every route. The CPLP Extradition Convention entered into force for Portugal on 1 March 2010, but it applies only where it is also in force between Portugal and the requesting state.

Who receives the request, and which court decides?

For traditional extradition, the PGR is Portugal’s central authority for receiving and transmitting international criminal-cooperation requests. Its role includes checking whether a request is properly prepared, compatible with Portuguese law and the Constitution, and accompanied by translations where needed. In the administrative stage, the PGR prepares its information for the Minister of Justice. The Minister decides whether the request may proceed or should be refused at that stage, including for political or opportunity-related reasons. This is a gatekeeping stage, not a final judicial finding that surrender is lawful.

If the request proceeds, the judicial phase belongs exclusively to the criminal section of the Tribunal da Relação for the judicial district where the person resides or is located at the time of the request. The working label “Tribunal da Relação of the district” is therefore broadly correct, but it is not one national extradition court: the person’s location and the statutory territorial rule identify the competent court. Portugal’s courts of appeal include the Tribunal da Relação de Lisboa, do Porto, de Coimbra, de Évora and de Guimarães. The local pages for Lisbon, Porto, Coimbra and Braga explain the district layer; the Faro page covers the Évora court district. The particular district matters for filing and hearings, but it does not create a separate local extradition code.

The court assesses the formal and substantive legal conditions, hears the requested person and decides whether extradition may be granted. Article 46(3) expressly excludes evidence aimed at proving or disproving the underlying criminal allegations as if Portugal were conducting the foreign trial. The question is whether the request satisfies the applicable extradition rules, not whether the Portuguese court should convict the person of the foreign charge.

What are the main stages and statutory time limits?

The table gives the principal statutory timetable for traditional extradition. These are deadlines for different steps, not a promise that every case will finish by one overall date. Treaty provisions, requests for supplementary information, the route by which detention began and an appeal can change which clock applies.

The administrative and judicial phases are urgent and run even during court vacations. The deadlines in the table are statutory targets or limits, not a reliable forecast of the total time from the first police alert to physical transfer. A case may require additional documents or assurances from the requesting state. Keep the date and source of every notice and order; the date of an INTERPOL alert, the date of arrest, the date a formal request reaches Portugal and the date it is filed with the court may be different.

What happens if the arrest comes before the formal request?

Portuguese law distinguishes a provisional arrest requested urgently before a full extradition request from a detention not directly requested but made on official information, including INTERPOL information. The difference matters because the first detention deadline and the later deadline for a decision by the Tribunal da Relação do not always run from the same date.

• Provisional arrest requested in advance: under Article 38, provisional detention normally ends if the formal extradition request is not received within 18 days from detention. For justified reasons invoked by the requesting state, it may be extended to a maximum of 40 days. A less restrictive measure may be available under Portuguese criminal procedure.
• Detention not directly requested: under Articles 39 and 64, the person must be brought before the competent judicial authority within 48 hours. If no information arrives that the foreign state intends to request extradition, release is due 18 days after arrest; if the state gives a positive indication but the formal request does not arrive, release is due 40 days after arrest.
• Formal request after early detention: for a detained person, the formal request must be brought before the court within 60 days of the effective arrest under Article 63(3). Article 63(4) says the 65-day decision period under Article 52(1) then runs from the date the formal request is filed in court, not automatically from the earlier provisional arrest.

The STJ judgment of 18 August 2023, case 1669/23.3YRLSB-A.S1, expressly held that where provisional or not-directly-requested detention precedes the formal request, Article 63(4) starts the Article 52(1) 65-day decision period from the date the formal request is filed in court. A later STJ judgment of 26 November 2025, case 2077/25.7YRLSB-B.S1, arose from an Article 39 arrest followed by a formal request; when rejecting habeas corpus, the STJ discussed the 65-day period and a possible 25-day extension, and applied the separate 80-day post-appeal limit after remitting the case for further steps. It did not expressly reconcile that analysis of the 65-day period with Article 63(4). We therefore cannot safely say that the later judgment confirms or overrules the 2023 interpretation. In a live case involving early detention, counsel should immediately verify the court-filing date, detention orders and the latest Portuguese authority, and assess both readings; do not infer a release date from the arrest date or this guide alone.

After an appeal against a decision granting extradition, detention may continue but, under Article 52(3), may not continue without a decision on that appeal for more than 80 days from the date the appeal is filed. If a constitutional appeal is brought, Article 52(4) sets a separate maximum of three months from that appeal’s filing. These are detention limits, not guarantees that the person will be released permanently or that the extradition request will fail.

What does the court check, and what is outside this page?

For traditional extradition, Article 31 generally requires the conduct to be punishable under both Portuguese law and the requesting state’s law by a custodial penalty with a maximum term of at least one year. If extradition is sought to enforce a sentence, the remaining sentence generally must be at least four months. The law also requires specific documents, including the foreign arrest warrant, the relevant judicial decision or conviction, the applicable limitation provisions and, in relevant cases, information about trial in absentia and the possibility of review or a retrial.

Those thresholds do not decide every case: the applicable treaty may set different or additional rules. Portuguese law addresses human-rights standards, discriminatory persecution, special courts, death or irreversibly injurious penalties, life or indefinite sentences, territorial jurisdiction and nationality, but the treaty can affect which grounds are available. In a CPLP extradition case, the STJ held on 3 January 2024 (case 2757/23.1YRLSB.S1) that the Convention’s listed refusal grounds are exhaustive and that general allegations about prison conditions did not establish individual risk on those facts. That holding is fact-specific: it should not be read as making general prison-condition allegations sufficient in every case, or as removing the need to assess any substantiated individual risk under the governing treaty and applicable fundamental-rights rules. Detailed refusal grounds, evidence strategy and appeals are covered by How to Stop Extradition from Portugal; this page does not replace that analysis.

Nor should an EAW be treated as ordinary extradition. Under Law No. 65/2003, the executing court normally must make a final decision within 10 days of valid consent to surrender or within 60 days after arrest where there is no consent. In exceptional cases, the period may be extended by a further 30 days, with reasons communicated to the issuing authority. Delivery ordinarily follows within 10 days of the final execution decision. The EAW has its own refusal rules, appeal provisions and mutual-recognition framework; it is not just a faster version of Law No. 144/99. Do not confuse Article 26’s decision deadlines with Article 30’s maximum-detention rules: under the latter, detention must cease if 60 days have elapsed from its start without a decision on execution, the limit is 90 days if an appeal is lodged, and it is 150 days if an appeal is brought before the Constitutional Court. Portugal’s constitutional rules on nationals must be read with Article 33(5) of the Constitution, which preserves EU criminal-justice cooperation. Requests from the United Kingdom or Iceland/Norway follow their separate surrender agreements, not the EAW regime as such; the applicable treaty and domestic implementing rules must be checked before applying any of these deadlines.

Can Portugal extradite one of its own citizens or a dual national?

Portuguese nationality is not a universal bar in every type of surrender, but traditional extradition of a Portuguese citizen is tightly limited. Article 33(3) of the Constitution and Article 32(2) of Law No. 144/99 require, among other things, a treaty basis, reciprocity, a case involving terrorism or international organised crime, and fair-trial guarantees in the requesting state. Under Article 32(3), traditional extradition for prosecution also requires a guarantee that the person will be returned to Portugal to serve any resulting sentence after the relevant Portuguese review and confirmation, unless the person expressly objects to return. The statute says nationality is assessed when the extradition decision is made. Where the request relies specifically on the European Convention on Extradition, Portugal’s Article 6 reservation against extraditing its nationals must also be applied; the constitutional and statutory exception is not a blanket override of that reservation, and another applicable treaty or EU surrender regime may produce a different analysis.

For an EAW, the EU cooperation rules must be analysed separately. A Portuguese citizen’s status does not by itself end the EAW procedure; the applicable provisions may permit refusal in a sentence-enforcement case if Portugal undertakes to enforce the sentence. For a dual national, gather proof of every nationality, residence and any pending Portuguese proceedings. Do not assume that a second passport removes Portuguese nationality or that the traditional-extradition rule decides an EAW case.

What does consent to extradition change?

Under Article 40 of Law No. 144/99, a detained person may consent to surrender and waive the ordinary extradition process after being informed of the right to that process. The statement must be signed by the person and counsel; the judge must verify that it is voluntary and that the legal conditions are met. Once judicially approved, the consent is irrevocable and the approval has the effect of a final decision. Consent can shorten the process, but it also removes the ordinary opportunity to contest the request through the full procedure.

Consent to surrender is not the same as waiving the speciality rule. Speciality concerns whether, after surrender, the requesting state may prosecute or punish the person for other conduct predating or contemporaneous with the conduct for which surrender was granted. The applicable treaty and any declaration made at the hearing matter. Before giving either declaration, the person should understand exactly what is being waived and whether a later prosecution, sentence or onward transfer could fall outside the authorised scope.

What happens after the court authorises extradition?

The final judicial decision authorising extradition is the operative basis for handover once it becomes final. Article 49 provides that an appeal from the final decision is heard by the criminal section of the STJ, and an appeal against a decision granting extradition has suspensive effect. The detailed grounds, filing deadline and any constitutional or habeas-corpus route are reserved for the remedies page linked above.

The transfer must respect the conditions under which surrender was authorised. The request must include a formal guarantee against re-extradition or prosecution for other earlier or contemporaneous facts, subject to the applicable treaty and recognised exceptions. A request to transit a person through Portugal is a separate question under Article 43; Portugal’s reservation under Article 21 of the European Convention likewise limits transit under that Convention to circumstances in which extradition itself could be granted. If the requesting state does not collect the person on the agreed date, Article 61 provides for release after 20 days, with a possible further extension of up to 20 days for force majeure. A handover date is therefore a distinct stage after the court decision, not the same event as the judgment.

What should the person and family prepare now?

A family member abroad can help without trying to contact witnesses or foreign authorities in a way that risks the case. Assemble a clean chronology and preserve the original documents. Do not rely on a screenshot of a Red Notice as a substitute for the actual judicial and extradition documents.

• Full name, date of birth, all nationalities, passport copies and any reliable proof of residence.
• The arrest record, court notice, detention order, hearing record and every document identifying the requesting state, warrant or INTERPOL alert.
• The formal extradition request and any translation, supplementary request, treaty citation or diplomatic assurance supplied to the Portuguese authorities.
• For a sentence-enforcement request: the judgment, confirmation that it is final, sentence imposed, time already served and time remaining.
• For a trial-in-absentia issue: the trial record and the requesting state’s rules or documents about appeal, review or a retrial.
• Medical records, family-care responsibilities, residence information and other documents relevant to a lawful request for a less restrictive measure, if counsel considers such an application available.
• A timeline with exact dates: initial alert, arrest, first hearing, receipt of the formal request, filing in court, written opposition, court decision and any appeal.

Hypothetical example: a person is arrested at Lisbon airport on information from a non-EU state before that state has sent its full request. The defence should not simply count 65 days from the airport arrest. It should identify whether Article 38 or Articles 39 and 64 governed the initial detention, record the 18-day and possible 40-day milestones, check the 60-day filing requirement for the formal request, and then calculate the Article 52 period from the legally relevant trigger. The exact treaty and the court district still need to be confirmed from the file.

How an extradition lawyer helps at each stage

At the outset, counsel identifies the route and treaty, checks the arrest and request documents, confirms the competent Tribunal da Relação, and makes sure the person can communicate with counsel and an interpreter. During the administrative stage, counsel can identify missing documents or treaty conditions and preserve a record of assurances. At the hearing and opposition stage, counsel prepares the procedural response, assembles admissible evidence and keeps the statutory dates visible. If the court authorises surrender, counsel assesses the available appeal route and detention timetable without assuming that an appeal automatically ends detention.

Cross-border coordination may be needed to obtain certified foreign decisions, limitation-law extracts, evidence of nationality or residence, or a binding assurance from the requesting state. A lawyer should explain which facts are relevant under Portuguese law, what is still missing, and which next deadline is actually running. No lawyer can promise a particular result or substitute a general guide for advice on the live court file.

How is the competent court district determined?

The competent Tribunal da Relação is determined by where the person resides or is located when the request is made, not simply by the family’s location or the place of arrest. Portugal’s appellate courts sit in Lisbon, Porto, Coimbra, Évora and Guimarães. For district-specific filing and hearing logistics, see the guides for Lisbon, Porto, Coimbra and Braga; Faro falls within the Évora district. These pages concern local logistics and do not change the national legal framework.
