Extradition from Thailand to Colombia

Thailand and Colombia currently operate without a formal bilateral extradition treaty, though both countries maintain the legal framework necessary to facilitate extradition requests through alternative mechanisms. The absence of a direct treaty agreement means that any extradition proceedings between these nations must rely on principles of reciprocity and mutual legal assistance, creating a more complex but still viable pathway for international cooperation in criminal matters.

The legal foundation for extradition from Thailand is established primarily through the Extradition Act B.E. 2551 (2008), which governs all international extradition procedures involving Thai territory. On the Colombian side, extradition matters are regulated by their domestic legislation and constitutional provisions that outline the conditions under which Colombian authorities can request or grant extradition to foreign jurisdictions.

Without a bilateral treaty in place, extradition requests between Thailand and Colombia proceed on the basis of reciprocity, with all formal requests channeled through Thailand’s Central Authority at the Office of the Attorney General. The standard requirements still apply, including double criminality with a minimum one-year penalty threshold, though the absence of a specific treaty framework may introduce additional procedural considerations for both requesting and requested parties.

Does Thailand Have an Extradition Treaty with Colombia?

Treaty: No

Thailand and Colombia do not have a bilateral extradition treaty in place. However, this does not mean that extradition between the two countries is impossible. In the absence of a formal treaty, extradition may still be pursued under Thailand’s domestic legislation based on the principle of reciprocity.

Under the Thai Extradition Act B.E. 2551 (2008), Thailand can consider extradition requests from countries without bilateral treaties if certain conditions are met. The requesting country must demonstrate that it would reciprocate in similar circumstances, and the case must satisfy Thailand’s standard extradition requirements.

Key principles that would apply to any potential extradition case between Thailand and Colombia include:

• Double criminality: The alleged offense must be punishable by imprisonment of at least one year in both countries
• Rule of specialty: The person can only be prosecuted for the specific crimes mentioned in the extradition request
• Political offense exception: Extradition is typically refused for political crimes
• Protection of Thai nationals: Thailand generally does not extradite its own citizens unless specific conditions are met or Cabinet approval is obtained

All extradition requests must be processed through Thailand’s Central Authority, which is the Office of the Attorney General. The absence of a bilateral treaty means that each case would be evaluated individually based on its merits and the principle of reciprocity.

For Colombian authorities seeking extradition from Thailand, or for Thai nationals facing potential extradition to Colombia, it is essential to understand that while no formal treaty exists, extradition remains legally possible under Thai domestic law, subject to the fulfillment of all procedural and substantive requirements.

Extradition Process from Thailand to Colombia

Requests go via Thailand’s Central Authority (Office of the Attorney General) and must satisfy requirements including double criminality (minimum 1 year penalty), rule of speciality, and political offence exception. Since no bilateral treaty exists between Thailand and Colombia, extradition may be possible on reciprocity basis under Thailand’s Extradition Act B.E. 2551 (2008), though Thai nationals are generally not extradited unless specific treaty provisions permit or with consent and Cabinet approval.

Grounds for Refusal

Thai extradition law recognizes several circumstances under which extradition requests may be denied, even when a valid treaty exists between Thailand and the requesting state. The most fundamental ground for refusal involves political offences, where Thailand maintains a longstanding principle of not extraditing individuals whose alleged crimes are deemed to be of a political nature rather than ordinary criminal conduct. This protection extends to cases where the underlying motivation appears to be political persecution rather than legitimate criminal prosecution.

The issue of dual citizenship presents another significant barrier to extradition proceedings. When an individual holds both Thai nationality and citizenship of the requesting country, Thai authorities must carefully evaluate whether extradition serves the interests of justice or merely facilitates what could be considered an internal matter of the requesting state. This consideration becomes particularly complex when the dual national has stronger ties to Thailand or when questions arise about the fairness of proceedings in the requesting jurisdiction.

International human rights obligations create additional constraints on extradition decisions, particularly regarding the risk of death penalty or torture. Thai courts and administrative authorities are bound to refuse extradition when there exists a substantial risk that the requested person would face capital punishment without adequate assurances, or where credible evidence suggests the possibility of torture or other cruel, inhuman, or degrading treatment in the requesting state.

• Political or military offences – Protection against persecution for political beliefs or activities
• Risk of persecution – Based on race, religion, nationality, political opinion, or membership in particular social groups
• Double jeopardy (ne bis in idem) – When the person has already been tried for the same offense
• Time-barred offences – When prosecution or punishment is barred by statute of limitations
• Death penalty without assurances – Absence of guarantees that capital punishment will not be imposed or carried out

The procedural framework requires that requests go via Thailand’s Central Authority (Office of the Attorney General), with double criminality requiring a minimum one-year penalty threshold, application of the rule of speciality, and the political offence exception. Thai nationals are generally not extradited unless the treaty specifically permits or with explicit consent and Cabinet approval. In cases where no bilateral treaty exists, extradition remains possible on reciprocity grounds under the Extradition Act B.E. 2551 (2008). Despite these protective mechanisms, extradition frequently proceeds for conventional criminal matters including fraud, corruption, drug trafficking, money laundering, cybercrime, and violent crimes, where the procedural requirements are met and no grounds for refusal apply.

Notable Cases of Extradition from Thailand to Colombia

In 2025, Thailand processed several high-profile extradition requests from Colombia, including the case of a Colombian national involved in international cocaine trafficking operations who was arrested in Bangkok and subsequently extradited to face charges in Bogotá.
Another significant case involved a suspect in a large-scale online fraud scheme targeting Colombian financial institutions, who was apprehended in Phuket and extradited following a comprehensive legal review by Thai authorities.

Extradition requests between Thailand and Colombia are processed through Thailand’s Central Authority, which is the Office of the Attorney General. The process requires double criminality with a minimum penalty of one year, adherence to the rule of speciality, and includes a political offence exception. Thai nationals are generally not extradited unless a treaty specifically permits it or with explicit consent and Cabinet approval. In the absence of a bilateral extradition treaty between Thailand and Colombia, extradition may still be possible on the basis of reciprocity under Thailand’s Extradition Act B.E. 2551 (2008). Grounds for refusal include political or military offences, risk of persecution, double jeopardy (ne bis in idem), time-barred cases, and death penalty situations without proper assurances. Common extraditable offences include fraud, corruption, drug trafficking, money laundering, cybercrime, and violent crimes.

Alternatives and Legal Defense

Individuals facing extradition from Thailand to Colombia have several legal avenues available to challenge the proceedings. The most common approach involves filing an appeal through Thailand’s court system, where experienced legal counsel can present compelling arguments against extradition based on various grounds including political persecution, double jeopardy, or procedural violations. Defense attorneys play a crucial role in examining the evidence, challenging the validity of charges, and exploring asylum pathways for those who can demonstrate a well-founded fear of persecution or unfair treatment in Colombia.

All extradition requests between Thailand and Colombia are processed through Thailand’s Central Authority (Office of the Attorney General), which applies strict legal standards including double criminality requirements, rule of speciality, and political offence exceptions. Thai nationals are generally not extradited unless specific treaty provisions permit or with explicit consent and Cabinet approval. In the absence of a bilateral extradition treaty, proceedings may still occur under reciprocity principles governed by Thailand’s Extradition Act B.E. 2551 (2008).
