Habeas-Style Relief — Section 90 Applications for Unlawful Detention
Applicant (detainee or relative) v State Authority Holding the Detainee
Composite summary — not a single reported case. This entry distils a settled line of Thai Supreme Court (Dika / ฎีกา) authority for legal education. It is not a transcript of one reported judgment, and the heading is not a citable case number. Do not cite it as specific case law — consult a Thai-qualified lawyer for the authoritative Dika number and current application.
Facts
A person was detained by police, immigration officers, military personnel, or other state authority. Relatives or counsel alleged that the detention was unlawful — for example, exceeding the maximum periods of police detention (48 hours) or court-ordered remand without further extension, detention without charge, or detention after the legal basis had lapsed (e.g. visa overstay detention beyond what is lawful).
Legal Issue
The scope and operation of Section 90 of the Criminal Procedure Code as the Thai analogue of habeas corpus.
Holding
The Supreme Court has confirmed that Section 90 CPC permits any interested person — the detainee, a relative, or counsel — to apply to the court for inquiry and release where there are grounds to believe a person is being detained unlawfully. The court must inquire urgently. If the detention is found unlawful, the court orders immediate release. The application is procedural, not a full criminal trial; it does not require the detainee to be physically present at filing.
Reasoning
Section 90 implements the constitutional protection of personal liberty (Section 28 of the Constitution). The remedy is urgent by design — the value of liberty is destroyed by delay.
Significance
Critical for criminal-defence and immigration-defence practice. Often the only available remedy where a detainee is held beyond lawful authority.
Practical Takeaway
If you suspect a relative or client is unlawfully detained, a Section 90 application can be filed without waiting for charges or for the prosecutor. Contact a lawyer immediately and provide names, locations, times, and the asserted legal basis (if any).
