Does Argentina Have Extradition? Process, Refusals, and Citizens

Yes, Argentina does have extradition. The country surrenders people wanted for prosecution or to serve a sentence abroad, either under a bilateral or multilateral treaty or, where no treaty exists, on the basis of reciprocity under Law No. 24.767 on International Cooperation in Criminal Matters.¹ The process runs through the federal courts and then the Executive Branch, and the person being sought has rights at every stage.

Which Offenses Can Trigger Extradition

Not every crime supports a request. Two threshold conditions apply.

The conduct must be criminal in both Argentina and the requesting country. That is dual criminality, and without it the request fails at the door.

The offense also has to be serious enough. Under Law 24.767, the test uses the “semisum” of the penalty: add the minimum and maximum prison terms and divide by two. If the result is at least one year, the offense qualifies.¹ Some treaties are simpler. The U.S.–Argentina treaty asks only whether the offense carries a maximum penalty of more than one year in both countries.²

When the person has already been convicted and sentenced, at least one year of that sentence must still be left to serve when the request is submitted.¹

When Argentina Will Refuse

Law 24.767 lists several situations in which extradition must be denied. These protections cannot be overridden by treaty.

Political offenses. The exception has hard limits: war crimes, crimes against humanity, attacks on heads of state or their families, and acts of terrorism are never treated as political.¹
Crimes that exist only under military law with no equivalent in ordinary criminal law.¹
Substantial grounds to believe the person would face torture or cruel, inhuman, or degrading treatment.¹
A possible death sentence, unless the requesting country gives sufficient assurances that it will not be imposed. The U.S.–Argentina treaty mirrors this.¹³
Substantial grounds to believe the request is really motivated by political opinions, nationality, race, or religion, or that defense rights would be compromised for any of those reasons.¹
Expiration of the criminal action or the punishment under the requesting country’s own law.¹
Prior trial for the same conduct in Argentina or any other country.¹
Conviction in absentia, unless the requesting country guarantees the case will be reopened with a chance to mount a defense.¹
Harm to Argentina’s sovereignty, security, or other essential public interests.¹

How the Process Works

An extradition request in Argentina moves through three stages.

Diplomatic Stage

The requesting country sends a formal request through diplomatic channels to the Ministry of Foreign Affairs, International Trade and Worship, which acts as the central authority for most treaties.⁴ Requests from the United States are the exception: they run through Argentina’s Ministry of Justice and Human Rights under the terms of the bilateral treaty. Once the paperwork is complete, the file goes to the federal courts.

Judicial Stage

A federal judge with criminal jurisdiction issues an arrest warrant if the person is not already in custody. Within 24 hours of the arrest, the judge holds a hearing where the person is informed of the details of the request, told of the right to counsel, and given a chance to speak. An interpreter is appointed if the person does not speak Spanish.¹

The judge then asks whether the person consents. If so, the judicial phase ends there. If not, the case proceeds to a fuller review where arguments against extradition can be presented. The court decides only whether extradition is legally permissible; it does not assess guilt or innocence. The decision can be appealed to Argentina’s Supreme Court, and the appeal suspends the extradition while it is pending.¹

Executive Stage

Once the courts have issued a final ruling, the file goes to the Executive Branch. If the court found extradition legally admissible, the Executive can still refuse it on grounds of sovereignty, public order, or essential national interests, and this is also the stage where the nationality option is invoked for Argentine citizens. The Executive has ten working days to decide. Silence past that deadline counts as approval.¹

The Executive’s power runs one way. It can block an extradition the court approved, but it cannot override a judicial refusal.

Surrender

Once extradition is granted, the requesting country has 30 calendar days to arrange transport. The Ministry of Foreign Affairs can extend that by ten additional days on request.¹

Provisional Arrest Before the Paperwork Arrives

Urgent cases don’t wait for the full request. A country can ask Argentina to provisionally arrest the person while it assembles the formal file, and this is often where INTERPOL Red Notices come in. The request must describe the person, summarize the facts, identify the applicable laws, and confirm that a formal extradition request is coming.

Under the U.S.–Argentina treaty, a provisionally arrested person must be released if the full request and supporting documents do not arrive within 60 calendar days. Release does not prevent re-arrest if the formal request eventually shows up.² Time limits vary under other treaties and under Law 24.767, so the deadline depends on which instrument governs.

Does Argentina Extradite Its Own Citizens

Sometimes. Argentina takes a middle path that turns on the applicable treaty.

Under Law 24.767, an Argentine national can choose to be prosecuted at home instead of being extradited, provided no treaty requires the extradition of nationals. If the person exercises this option, Argentina refuses extradition and takes on the prosecution itself. The requesting country then has to waive its own jurisdiction and hand over the evidence.¹ The person must have been an Argentine national both when the offense was committed and when the option is exercised.

Some treaties override this protection. The U.S.–Argentina treaty explicitly states that extradition cannot be refused on the basis of nationality.³ An Argentine citizen wanted by the United States generally cannot invoke the nationality option.

What the Receiving Country Can Do Afterward

Argentina’s cooperation is limited to the specific case in front of it. Under the specialty principle, the requesting country can only try the person for the offense that justified the extradition, or for a less serious offense based on the same facts. Prosecution for anything else, or re-extradition to a third country for pre-surrender offenses, requires Argentina’s consent.¹

These protections lapse if the person voluntarily stays in the requesting country for 30 days after being free to leave, or leaves and then voluntarily returns.²

Consenting to Extradition

A person facing extradition can consent at any stage. If they do, the court skips the remaining proceedings and grants extradition directly. The requesting country first has to guarantee that it will pay for the return trip if the person is ultimately acquitted, though the person can waive even that protection for an immediate transfer.¹ Consent is also possible during provisional arrest, before the formal request has arrived. It is not common, but it can compress a process that otherwise runs for months.
