THAILAND EXTRADITION

Grounds to Challenge Extradition in Thailand

Key Takeaways

Thailand is not required to extradite. The Act and the treaty both set out refusal grounds.
The Criminal Court in Bangkok decides, so the case turns on evidence rather than diplomacy.
Six grounds decide most cases, from absence of dual criminality to risk of unfair treatment.
The requesting state normally has sixty days from provisional arrest to file its formal request.

Thailand is not obliged to surrender every person another state asks for. The Extradition Act B.E. 2551 (2008) and the applicable bilateral treaty both set out grounds on which extradition must or may be refused, and each of those grounds has to be raised and proved before the Criminal Court in Bangkok. However, the grounds must be considered on a case-by-case basis.

This page sets out the grounds our clients rely on most often, what each one requires in evidence, and when in the process it has to be raised.

Extradition Is Decided by a Court, Not a Ministry

An extradition request reaches Thailand through diplomatic channels, often after a provisional arrest based on an Interpol Red Notice. The Attorney General examines the request and, if satisfied that it meets the statutory requirements, petitions the Criminal Court. The court then decides whether the conditions for surrender are met, and its decision may be appealed. Only after the judicial stage is complete does the matter return to the Government for the final surrender decision.

That structure matters. Because a court decides, the case is won or lost on legal argument and evidence rather than on diplomacy alone.

The Grounds Most Often Argued

Which grounds are available in a particular case depends on the treaty in force, on how the requesting state has framed the offence, and on the stage the case has reached. The following are the grounds that decide real cases in Bangkok.

Absence of Dual Criminality

The conduct alleged must be a criminal offence under Thai law as well as under the law of the requesting state, and it must reach the level of seriousness the treaty requires. Offences that exist abroad but have no Thai equivalent, and offences drafted so broadly that the Thai equivalent does not cover the actual conduct, both fail this test. Establishing it requires a careful comparison of the foreign charge against the Thai Penal Code, not a translation of the charge sheet.

Political, Military, Religious or Racial Offence

Extradition may be refused where the offence is political in character, or where the request, although framed as an ordinary criminal matter, is in substance an attempt to prosecute or punish a person for their political opinions, religion, race or nationality. Purely military offences are excluded on the same basis. This ground calls for evidence about the case as a whole, including the conduct of the proceedings abroad and the treatment of comparable defendants.

Limitation and Lapse of Time

Where prosecution or punishment would be time barred under the law of either Thailand or the requesting state, extradition can be resisted. Long delay between the alleged offence and the request is relevant even where the limitation period has not expired, because it affects the fairness of any trial that follows.

Double Jeopardy

A person who has already been tried, convicted or acquitted for the same conduct should not be surrendered to face it again. Establishing this requires certified records from the earlier proceedings and, in most cases, an opinion on whether the two sets of charges concern the same facts.

Thai Nationality

Where the person sought is a Thai national, the treaty may permit Thailand to refuse extradition, sometimes on the basis that the case is instead submitted to the Thai authorities for prosecution. Whether this is available and whether it is advantageous both depend on the treaty text and on the facts.

Risk of Treatment Contrary to Fundamental Rights

Extradition may be resisted where there is a real risk of torture or inhuman or degrading treatment, of a trial that does not meet basic standards of fairness, or of a conviction entered in absentia with no genuine right to a rehearing. Country evidence, expert reports and material from international bodies are usually required.

A Ground Is Only as Strong as the Evidence Behind It

Each of these grounds stands or falls on the record put before the court: certified translations of the foreign file, opinions on the law of the requesting state, the full procedural history of the case abroad, and expert evidence on conditions of detention where that is in issue. Assembling that record takes weeks.

This is why the period following a provisional arrest is not dead time. The requesting state normally has sixty days from provisional arrest to file its formal request, and the work done in that window decides what can be argued once the hearing begins.

Where the Parallel Red Notice Fits

A refusal of extradition in Thailand does not delete the Interpol Red Notice that may have led to the arrest. The notice remains in circulation and continues to affect travel, banking and residence in other countries until it is challenged in its own right before the Commission for the Control of Interpol’s Files.

The factual grounds that defeat an extradition request usually support an application to Interpol as well, and the two files are best prepared together rather than one after the other.

Frequently Asked Questions

Can extradition be refused if there is no treaty with the requesting country?

The absence of a treaty is not itself a ground of refusal. Thailand may extradite on the basis of reciprocity. However, non-treaty requests leave more room for argument on procedure and on the sufficiency of the undertakings given by the requesting state.

At what point should these grounds be raised?

As early as possible. Several can be put to the Attorney General before the matter reaches court, and the evidence supporting all of them takes weeks to gather. Waiting for the hearing is the most common avoidable mistake.

Does a refusal of extradition end the matter?

Not necessarily. The underlying warrant in the requesting state remains, and any Interpol Red Notice remains in circulation unless it is separately challenged.

Can bail be granted while an extradition case is pending?

Bail is possible but not automatic, and the court will weigh flight risk heavily in an extradition matter. An application should be prepared with that in mind from the outset.

Is an extradition request already filed against you ?

If an extradition request has been made against you or someone close to you, the grounds available in your case depend on the treaty, the charge and the stage the matter has reached. Contact Herrera and Partners for a confidential assessment.
