Key Takeaways
- Section 9 of the Extradition Act excludes offences of political character and military offences from extradition.
- Without a treaty, Thailand surrenders only where the requesting state demonstrates it would extradite to Thailand in return.
- Refusals happen: the Criminal Court rejected the Viktor Bout request in 2009, reversed on appeal in 2010.
- Herrera & Partners (H&P) has built legal strategies to oppose extraditions in Thailand; each case turns on its own facts.
Extradition is a complex and sensitive legal process in which one state formally requests another to surrender an individual for prosecution or to serve a sentence.
In Thailand, the process is governed primarily by the Extradition Act B.E. 2551 (2008), which provides a legal framework for evaluating and responding to such requests.
However, extradition in Thailand is not automatic, and authorities have several legal and practical grounds to refuse cooperation. Understanding these grounds is essential for both individuals and legal practitioners handling extradition matters.
At our law firm in Thailand H&P, we have previous experience creating legal strategies to oppose extraditions in Thailand, but each case is different and there is no single solution for all cases of extradition in Thailand.
| Ground | What has to be shown |
| No treaty or reciprocity | No bilateral treaty, and no assurance of reciprocity from the requesting state |
| Lack of dual criminality | The alleged conduct is not a criminal offence under Thai law |
| Political or military offence | The request is motivated by political considerations or targets a military-only offence |
| Human rights risk | A real risk of torture, inhumane treatment, or the death penalty in the requesting state |
| Procedural defect | Errors, identity mismatch, or missing documentation in the request |
| Prior punishment or time bar | The person already served the sentence, was pardoned, or the statute of limitations expired |
No treaty and no reciprocity
One of the fundamental legal considerations is the existence of a bilateral extradition treaty or reciprocity between Thailand and the requesting state.
Thailand generally extradites only when there is a formal treaty in place, or when the requesting state provides assurances of reciprocity. Without such a treaty or guarantee, extradition may be denied, reflecting Thailand’s principle of protecting sovereignty and ensuring that legal cooperation is mutual.
Lack of dual criminality
Another critical criterion is dual criminality. Under Thai law, the act for which extradition is requested must constitute a criminal offense in both Thailand and the requesting country. If the conduct alleged is not punishable under Thai law, extradition cannot proceed.
This ensures that Thai courts do not facilitate the prosecution of acts that are not considered illegal domestically and prevents misuse of the extradition process for acts that are culturally or legally acceptable in Thailand.
Political and military offences
Extradition is also prohibited for political or military offenses. Thai law recognizes that requests motivated by political considerations may involve persecution rather than legitimate criminal prosecution.
For instance, an individual accused of dissenting against a foreign government, engaging in political activism, or committing acts considered political rather than criminal would typically not be surrendered. This safeguard reflects Thailand’s commitment to protecting individuals from politically motivated persecution.
Human rights risks: torture, inhumane treatment and the death penalty
Human rights considerations are central to the Thai extradition process. If the person subject to extradition faces the risk of torture, inhumane treatment, or the death penalty in the requesting country, Thai authorities have the discretion to refuse cooperation.
Courts and central authorities must carefully assess whether surrendering the individual would violate fundamental rights or international human rights obligations, ensuring that extradition does not result in cruel or disproportionate treatment.
Procedural defects, time limits and prior punishment
Procedural issues can also provide valid grounds to deny extradition:
- Errors in the request
- Identity mismatches
- Incomplete or missing documentation
- Other administrative deficiencies
Extradition is also legally impossible under Thai law if the individual has already:
- Served the sentence
- Been pardoned
- Had the statute of limitations expire
These procedural safeguards ensure the fairness and integrity of the process, preventing arbitrary or unjust enforcement.
The role of Thai courts and the Attorney General
The role of Thai courts in extradition cases is largely limited to confirming the identity of the person requested and ensuring that the legal and procedural requirements are met.
The Office of the Attorney General and other central authorities hold discretion to approve or reject extradition requests, taking into account public interest, fairness, and human rights considerations. Courts and authorities evaluate whether the request fits Thai law, the treaty framework, and principles of justice before any decision is made.
How courts have applied these grounds
Recent cases illustrate how these safeguards operate in practice. There have been instances where extradition requests were delayed or refused because of procedural irregularities, inadequate documentation, or concerns about human rights violations in the requesting country.
Such cases demonstrate the importance of a thorough legal review and the ability of Thai authorities to exercise discretion to prevent injustice. Legal counsel plays an important role in guiding individuals through this process, advising on potential defenses, and ensuring compliance with both domestic and international law.
Multiple legal and procedural safeguards exist to ensure that extradition respects both international cooperation obligations and the fundamental rights of individuals, particularly when the request comes from a country with a different legal system or human rights record.

Frequently asked questions
Can Thailand refuse extradition when there is no treaty?
Yes. Under Section 9(2) of the Extradition Act, without a treaty the Government may surrender only if the requesting state demonstrates it would extradite to Thailand in the same manner.
Does Thailand extradite for political offences?
No. Section 9(1) excludes offences of political character and military offences. Killing or attacking a head of state or their family does not count as political.
Can the death penalty block an extradition from Thailand?
It can. Thailand’s treaties, for example with Canada, allow refusal where the offence carries death in the requesting state unless it gives assurances the sentence will not be carried out.
Has a Thai court ever refused an extradition request?
Yes. In August 2009 the Bangkok Criminal Court refused the US request for Viktor Bout, finding the case political. The Court of Appeal reversed that in August 2010.
Who has the final say on refusing extradition in Thailand?
The Criminal Court rules first, with a 30-day appeal to the Court of Appeal under Section 21. Section 9 then leaves the surrender decision to the Government of Thailand.
