How an Extradition Case Moves Through Thai Courts: The Deadlines That Matter
A person arrested in Thailand on a foreign request faces a process with short, fixed time limits. The Extradition Act B.E. 2551 (2008) sets most of them, and a missed deadline can end a defence before it starts. This article walks through the stages using the text of the Act itself.
Who receives the request
Under Section 5 of the Act, the Central Authority is the Attorney General or a person the Attorney General designates. Section 8 sets two routes: requests from treaty partners go to the Central Authority, while requests from other states arrive through diplomatic channels.
The request has to describe conduct that is a crime in both countries. Section 7 requires an offence punishable by death or by loss of liberty of one year or more, under the law of both the requesting state and Thailand.
The stages in order
| Stage | What the Act provides |
| Provisional arrest | Allowed in urgent cases before a formal request arrives (Section 15) |
| Formal request window | Release if no request and accusation arrive within 60 days, or a court-fixed period of up to 90 days (Section 16) |
| Court hearing | The Public Prosecutor brings the case to court promptly after arrest (Section 18) |
| Appeal | 30 days for either side to appeal a release or detention order; the Appeal Court’s decision is final (Section 21) |
| Surrender | Within 90 days of the court’s final order, unless the court extends it on the prosecutor’s petition (Section 22) |
Provisional arrest and the 60-day clock
Foreign authorities can ask for an arrest before the paperwork is ready, which is why many people learn of a request only when police detain them. From that day the 60-day clock runs. If the formal request and accusation haven’t arrived by the end of it, or by a longer date of up to 90 days that the court has fixed, the person must be released.
Bail follows the Criminal Procedure Code under Section 18. The court asks the Public Prosecutor whether there is any objection to a release petition before it rules.
The hearing
At the hearing the court tests whether the offence meets the Act’s conditions. Questions it can take up include:
- Whether the conduct is a crime in both countries
- Whether the offence is political or military in character
- Whether the person has already been tried, acquitted, pardoned or served a sentence for the same conduct (Section 10)
- Whether the person in custody is the person named in the request
Section 9 excludes political and military offences from extradition, though attacks on the King, Queen or Heir Apparent fall outside that exception.
The consent track
Under Sections 27 and 28, a person can consent to extradition. The arresting authority records the consent on the Central Authority’s form, and the prosecutor asks the court to examine it. If the court finds the consent voluntary, it orders detention for surrender. Consent given before the court can’t be withdrawn, and a consent given during a pending hearing suspends the hearing.
That irrevocability is the reason the decision needs to be made with full information. Someone who consents quickly to end detention may lose the chance to raise a defence they would have won.
Why representation matters early
The stages are short and the first one, provisional arrest, happens without notice. People in custody on a foreign request often look for Thailand Extradition lawyers because the 30-day appeal window and the 60-day formal-request window leave little room for delay. A lawyer can check the request against Section 7, raise the political-offence and double-jeopardy bars where they apply, and make sure any consent is a considered choice.
After the court rules
After the court rules, the Thai government decides whether to surrender the person, and diplomatic and human rights factors can enter that decision. Once the order is final and the government has decided to surrender, Section 22 gives 90 days to complete the handover.
Section 11 then limits what the receiving state can do. The person can’t be tried for other earlier offences, or passed to a third state, unless the Thai side consents, the person stays beyond 45 days after the process ends, or the person leaves and later returns.
The practical step for anyone facing a request is to obtain a copy of the formal request and the arrest warrant, then calendar the 60-day and 30-day dates from the day of arrest and the day the order is read.
