HomeOverview of Thailand–Portugal Extradition
Thailand and Portugal do not have a bilateral extradition treaty in place. No formal extradition agreement has been signed between the two countries, and consequently, there is no treaty that has entered into force governing extradition procedures between Thailand and Portugal.
In the absence of a bilateral treaty, extradition matters between Thailand and Portugal are governed by Thailand’s Extradition Act B.E. 2551 (2008) and Portugal’s corresponding domestic legislation. Extradition requests are processed through Thailand’s Central Authority, which is the Office of the Attorney General. Key principles apply including double criminality (requiring a minimum penalty of one year), the rule of speciality, and the political offence exception. Thai nationals are generally not extradited unless specifically permitted by treaty or with consent and Cabinet approval. Without a bilateral treaty, extradition may still be possible on the basis of reciprocity under Thailand’s Extradition Act B.E. 2551 (2008).
Does Thailand Have an Extradition Treaty with Portugal?
- Treaty status: No
Thailand does not have a bilateral extradition treaty with Portugal. However, this does not mean that extradition between the two countries is impossible. Under Thai law, specifically the Extradition Act B.E. 2551 (2008), extradition can still occur on the basis of reciprocity even without a formal treaty.
In cases where no bilateral extradition treaty exists, Thailand may consider extradition requests from Portugal if certain conditions are met. The principle of reciprocity means that Thailand would expect Portugal to similarly consider Thai extradition requests in the future. All extradition requests must go through Thailand’s Central Authority, which is the Office of the Attorney General.
Key requirements that would apply to any extradition request between Thailand and Portugal include:
- Double criminality: The alleged offense must be punishable by imprisonment for at least one year in both countries
- Rule of specialty: The requesting country can only prosecute for the specific crimes mentioned in the extradition request
- Political offense exception: Individuals cannot be extradited for political crimes
- Thai nationals protection: Thai citizens are generally not extradited unless specifically permitted by treaty terms or with special consent and Cabinet approval
Without a formal treaty framework, the extradition process between Thailand and Portugal would likely be more complex and uncertain, requiring careful legal analysis of each individual case under the reciprocity provisions of Thai extradition law.
Extradition Process from Thailand to Portugal
Extradition requests from Portugal to Thailand are typically initiated by Portuguese judicial authorities, including prosecutors or investigating judges, and submitted through diplomatic channels via the Portuguese Ministry of Justice to the Thai Ministry of Foreign Affairs. The Thai Attorney General’s Office serves as the central authority for processing extradition requests and coordinates with relevant Thai judicial bodies to evaluate the legal merits of each case. Since Thailand and Portugal do not have a bilateral extradition treaty, requests are processed under Thailand’s domestic extradition laws and principles of international cooperation.
The judicial review process involves multiple stages within the Thai court system, beginning with an initial assessment by Thai prosecutors who examine whether the request meets basic legal requirements. If the case proceeds, it moves to the Thai Criminal Court, which conducts a formal hearing to determine whether the evidence supports extradition and whether the alleged crimes would constitute offenses under Thai law (dual criminality requirement). The court’s decision can be appealed to higher courts, and the final determination rests with Thai judicial authorities, subject to approval by the Thai Cabinet and relevant ministries.
The extradition process from Thailand to Portugal typically takes between 12 to 24 months to complete, though complex cases involving multiple charges or legal challenges can extend significantly longer. Factors affecting the timeline include the completeness of documentation provided by Portuguese authorities, the complexity of legal arguments presented, potential appeals through Thai courts, and administrative processing times between various government agencies. Cases involving high-profile individuals or politically sensitive matters may experience additional delays due to enhanced scrutiny and diplomatic considerations.

| Ground | Explanation |
|---|---|
| Political offenses | Thailand typically refuses extradition for offenses of a political nature, as these are generally excluded under international extradition principles and Thai law. |
| Dual nationality | Thai nationals holding dual citizenship with Portugal may be protected from extradition, with Thailand often preferring to prosecute its own citizens domestically rather than surrender them to foreign jurisdictions. |
| Risk of death penalty / torture | Extradition will be refused if there is a substantial risk that the requested person will face the death penalty, torture, or inhuman treatment in Portugal, unless adequate assurances are provided. |
| Custom refusal grounds | Additional grounds include: Political/military offences that fall outside criminal law; risk of persecution based on race, religion, nationality, or political opinion; double jeopardy (ne bis in idem) where the person has already been tried for the same offense; time-barred cases where prosecution is statute-barred; and death penalty cases without proper diplomatic assurances. |

Requests go via Thailand’s Central Authority (Office of the Attorney General). Double criminality (minimum 1 year penalty), rule of speciality, and political offence exception apply. Thai nationals are generally not extradited unless treaty permits or with consent/Cabinet approval. If no treaty exists, extradition remains possible on reciprocity under Extradition Act B.E. 2551 (2008). With Portugal, no bilateral treaty exists, but reciprocity arrangements may still facilitate proceedings.
