How to Stop Extradition from Thailand: Grounds for Refusal, Appeals and Deadlines

Who can stop the request, and at which stage?

Thailand's Attorney General, or a designated official, acts as the Central Authority under section 5. The Office of the Attorney General screens and coordinates requests, and a public prosecutor brings the matter before a court. In the ordinary Bangkok cases considered here, the Criminal Court (ศาลอาญา) decides whether section 19 justifies detention for extradition; an appeal goes to the Court of Appeal (ศาลอุทธรณ์). The Criminal Court's central role is confirmed by Thai practice, but the actual court and file number must be checked rather than assumed from the arrest city.

The court does not decide every foreign-policy or protection question. Sections 13–14 of the Extradition Act assign screening and routing functions to the Ministry of Foreign Affairs and the Central Authority; the Act also reserves a separate government decision about surrender, particularly under sections 9 and 22. Section 13 of the separate 2022 Prevention and Suppression of Torture and Enforced Disappearance Act binds Thai authorities independently of the Extradition Act’s section 19 evidential test. Counsel may therefore need both a judicial defence under section 19 and a documented protection submission to the Attorney General/Central Authority and the authority responsible for final surrender. An informal letter or ordinary extradition appeal should not be assumed to suspend transfer without an applicable legal basis or order.

Which objections can defeat the court case?

Identify the act rather than arguing only about the foreign offence label. The court may admit the requesting state's authenticated documents without hearing the foreign witnesses in person; section 8 requires documentation submitted to a Thai court to have a certified Thai translation. Ask counsel to compare those translations with the actual warrant, dates and elements of each offence. A foreign case that looks weak politically is not automatically a weak prima facie case under section 19.

What if return would expose the person to torture or disappearance?

Section 13 of Thailand's Prevention and Suppression of Torture and Enforced Disappearance Act B.E. 2565 (2022) prohibits Thai state agencies and officials from expelling, deporting or extraditing a person to another state where there are substantial grounds for believing that the person would be in danger of torture, cruel, inhuman or degrading treatment, or enforced disappearance. Thailand is also party to the UN Convention against Torture, in force for Thailand since 1 November 2007; article 3 prohibits return where there are substantial grounds for believing that the person would be in danger of torture. The International Convention for the Protection of All Persons from Enforced Disappearance entered into force for Thailand on 13 June 2024 after ratification on 14 May 2024; article 16 separately prohibits expulsion, return or extradition where there are substantial grounds for believing that the person would be in danger of enforced disappearance. These domestic and treaty protections are related but distinct legal bases.

Prepare a specific, individualised record: treatment of co-accused, detention-facility evidence, threats, medical reports, reliable country materials, written assurances and reasons any assurances do not remove the risk. Raise it promptly through Thai counsel with the Central Authority and the authority handling final surrender; ask counsel to verify whether urgent judicial relief is available in the exact procedural posture. Do not assume the section 21 Court of Appeal can conduct a free-standing human-rights merits appeal. Section 21 expressly limits its review to the section 19 criteria and sufficiency of evidence. The 2022 anti-torture prohibition is a separate obligation, but it does not by itself produce an automatic release order or identify a universally available injunction procedure.

Which clock controls the defence?

Under section 23, a requesting state's unjustified failure to take custody within the statutory surrender period can also affect a later request for the same offence. That is not a substitute for making an appeal now. A treaty may contain an additional, different provisional-arrest rule: for example, the 1984 Thailand–Philippines treaty states a 20-day provisional-arrest termination provision in article X(5). The actual treaty's status, applicability and interaction with Thai legislation must be verified before calculating a deadline. Different statutory clocks must never be added together.

What can the Court of Appeal actually decide?

Section 21 allows the requested person or public prosecutor to appeal a first-instance release or detention order to the Court of Appeal. The court tests whether there was sufficient evidence for the criteria listed in section 19. Its decision under the Extradition Act is final; the statute does not provide another ordinary appeal on the extradition merits to the Supreme Court (ศาลฎีกา). A contested interpretation of an extradition offence, identity, nationality or the sufficiency of evidence should therefore be structured around section 19 and preserved in the appeal record.

Thailand's Constitutional Court (ศาลรัฐธรรมนูญ), decision No. 21/2568 dated 22 October 2025, considered a constitutional objection referred by the Court of Appeal in the She Zhijiang extradition litigation. It unanimously held that the challenged parts of sections 19 and 21 of the Extradition Act were not contrary to the constitutional provisions under review. This is a significant limit on arguments that those statutory provisions are themselves unconstitutional; it is not a new appeal on the facts and does not remove section 21's express finality rule. Under section 212 of the 2017 Constitution, a court hearing a pending case may refer a relevant constitutional question to the Constitutional Court. That referral is not a second merits appeal or a guaranteed stay available simply by filing a direct request after the extradition appeal has ended.

Does every requesting country face the same test?

No. Section 4 makes the domestic Act operate subject to applicable treaty provisions. The 1984 Thailand–Philippines extradition treaty has its own nationality, double-jeopardy, political-offence and provisional-arrest clauses, which must be checked if that treaty governs the request. Section 9(2) allows a request even without a bilateral extradition treaty if the requesting state clearly provides the required reciprocity. The lack of a treaty alone therefore does not stop extradition.

Do not import European procedures into Thailand. Thailand is not an EU Member State; a European Arrest Warrant cannot be executed as an EAW against a detainee under Thai extradition law. The European Court of Human Rights and its Rule 39 measures are not a Thai appellate forum: Thailand is not bound by the European Convention on Human Rights. A treaty-specific objection should name the actual requesting country and operative instrument, not copy a defence available in a different legal system.

Can international emergency measures stop a Thai surrender?

An application for an international interim measure is not an automatic stay of a Thai extradition order. Thailand is outside the European Convention system, so ECtHR Rule 39 does not operate against Thailand. Thailand has reserved against article 22 of the Convention against Torture and has stated that it does not consider itself bound by that article; the Committee against Torture's individual-communication procedure is therefore unavailable against Thailand under article 22. Thailand has also made no declarations under articles 31 and 32 of the Convention on Enforced Disappearance accepting the Committee's competence to receive individual or inter-State communications. A communication to UN special procedures is not an enforceable Thai court order and does not automatically stop transfer. The immediate priority is evidence-backed domestic protection under section 13 and identifying the authority responsible for the surrender decision.

How can detention be challenged while the request proceeds?

Section 18 permits an application for provisional release (similar to bail), and applies the Criminal Procedure Code where the Extradition Act has no contrary rule. The court asks for the prosecutor's position and may consider an objection. The court must check whether the requested person has counsel and appoint one if the person wants a lawyer but lacks one. Prepare residence information, identity papers, a realistic appearance undertaking and documents addressing particular risks; release is discretionary, not promised by the expiry of a fixed number of days.

If the court has ordered release but the prosecutor appealed within the 72-hour notice period, section 19 allows detention pending that appeal. The person may still seek provisional release at appeal stage under the cross-reference to section 18(3). These detention questions are distinct from the right to challenge the section 19 surrender criteria. Separately, release under section 16 because a formal request did not arrive on time does not prevent a later ordinary formal extradition request, although the same provisional-arrest basis cannot simply be reused.

What decisions can be irreversible?

Sections 27 and 28 permit consent to extradition before or during the proceedings. After questioning by officials, a written consent goes before the court, which checks voluntariness. Once given before the court, that consent cannot be revoked under those sections, and an ongoing hearing can be terminated for surrender. A detainee should not sign a document described informally as a routine acknowledgment without a Thai-language explanation, independent advice and confirmation whether it is actually an extradition consent. The statute does not treat a casual waiver of a hearing and a legally effective consent as interchangeable.

Nor does a successful objection automatically mean the person may remain in Thailand. Extradition, immigration removal, a UNHCR registration and Thailand's National Screening Mechanism are separate processes. Its National Screening Mechanism began in September 2023, but UNHCR explains that an application there does not independently confer immigration status or immunity from arrest. Any protection claim must be coordinated with the section 13 prohibition against dangerous return, including the risk of indirect onward removal.

How should the next decision be made?

1. If arrested provisionally: obtain the section under which detention was ordered, the arrest time and the court's current 60/90-day calculations; ask counsel about provisional release.
2. If the merits hearing is pending: assemble Thai-translated identity, charge, treaty, limitation and prior-judgment records; challenge each missing section 19 element.
3. If the first-instance order was read: lodge a properly reasoned section 21 appeal within 30 days; do not rely on informal negotiations to keep the deadline open.
4. If torture or disappearance risk exists: present it urgently with evidence to counsel for the executive surrender process and separately examine whether protective judicial relief is available.
5. If the appeal is final: verify the current detention and surrender orders, the 90-day clock and any authorised extension; do not assume a new constitutional complaint automatically stops transfer.

Hypothetical example: A Georgian national is arrested in Bangkok following a provisional request alleging an economic offence. Counsel discovers that the requesting state's charge is punishable there, but the particular alleged conduct may not satisfy an equivalent Thai criminal provision. The lawyer develops a section 7/19 comparison for the Criminal Court, checks the section 16 arrest clock and prepares an appeal deadline sheet. If the person also faces substantiated torture risk abroad, counsel prepares a separate section 13 submission for the competent government authorities; the court's dual-criminality analysis cannot be assumed to resolve that issue.

Five mistakes that can cost the defence

• Counting 30 days from a lawyer's receipt of papers instead of the date the order was read.
• Treating a Red Notice as a Thai arrest warrant: INTERPOL itself says a notice is an alert, not a warrant; the Thai legal basis for detention still matters.
• Using the old 1929 Act's 15-day appeal or 48-hour release periods instead of the 2008 Act.
• Calling any fair-trial concern an automatic section 19 defence, without identifying the executive and anti-torture routes while checking whether the point falls within section 19 and, separately, whether section 13 protection applies.
• Signing consent, or ignoring a treaty-specific exception, before counsel has examined its precise effect.
