Suspect Rights You Should Know
สิทธิพื้นฐาน

The Presumption of Innocence
Both Thai and international law establish that a suspect or defendant is not guilty until convicted by a final judgment. This is the "presumption of innocence," enshrined in Section 29 of the 2017 Constitution of Thailand and reflected in the Universal Declaration of Human Rights.
The principle places the burden of proof on the prosecution. The accused does not have to prove their innocence and is granted multiple rights to defend themselves throughout the criminal process.
Legal Foundations of Suspect Rights
- Constitution Sections 28–29 — Right to life and liberty; presumption of innocence.
- Criminal Procedure Code (CPC) — Sections 7/1, 7 ter, 134, 134/1.
- Anti-Torture and Enforced Disappearance Act B.E. 2565 (2022) — A new law providing additional protections, including video recording at arrest.
- International Covenant on Civil and Political Rights (ICCPR) — Thailand is a signatory.
Eight Rights Every Suspect Should Know
1. Right to Be Informed
Under CPC Section 7/1, officers must promptly inform the suspect of the charges and rights, in language they understand, before any interrogation begins.
2. Right to Counsel
Under CPC Section 7 ter, suspects have the right to a lawyer present during questioning from the very first stage. If unable to afford counsel, the state must provide one in cases involving imprisonment, juveniles, or persons unable to defend themselves.
3. Right to Silence
Under CPC Section 134, the suspect may "give a statement or remain silent." Statements may be used as evidence in court. Silence cannot be held against the accused, and the court must not draw adverse inferences from it.
4. Right to Private Consultation with Counsel
Suspects have the right to meet and consult their lawyer privately, free from surveillance, so that they can speak fully and receive proper advice.
5. Right to Be Free from Torture or Coerced Confession
Beating, threats, rewards, or promises in exchange for a statement are strictly prohibited. Statements obtained unlawfully cannot be used as evidence. The Anti-Torture Act of 2022 also requires audio-video recording during arrest and the first 24 hours of detention.
6. Right to Bail
A constitutional right. The accused may apply for bail throughout the case, except where strong evidence and flight risk justify continued detention. See our article "Bail for Suspects and Defendants" for details.
7. Right to Present and Cross-Examine Witnesses
The accused may present witnesses and evidence to prove innocence and may cross-examine prosecution witnesses in court.
8. Right to an Interpreter
A suspect who does not understand Thai is entitled to a state-provided interpreter, both during investigation and at trial, free of charge.
The Anti-Torture Act of 2022
Effective 22 February 2023, this Act provides additional protections, including:
- Mandatory audio-video recording of arrest, interrogation, and the first 24 hours of detention.
- The arrested person's right to immediately notify family.
- Criminal penalties for officials who torture or cause enforced disappearance.
- An investigative committee for complaints.
If Your Rights Are Violated
- Notify your lawyer immediately — Document the violation in writing.
- Request a medical examination — If injured, obtain a medical certificate.
- File a motion with the court — The court can order release or transfer to another facility.
- Complain to the National Human Rights Commission — Or to the investigation committee under the Anti-Torture Act.
- File criminal and civil cases — Against the responsible officers and claim damages.
Hypothetical Case Studies (Educational)
Case 1 — Exercising the right to silence: Mr. A is arrested on drug charges. Officers pressure him to sign a statement. He invokes his right to silence until counsel is present and asks to notify his family. When his lawyer arrives, the lawyer reviews the evidence and finds the arrest was unlawful. The case is dismissed.
Case 2 — Coerced statement: Mr. B is beaten to obtain a signed statement. His lawyer requests a medical examination, obtains a medical certificate, and presents it in court. The court excludes the coerced statement and the responsible officers face criminal charges.
Case 3 — Foreign national: Mr. C, a British national, is arrested for fraud. Officers do not provide an interpreter. Mr. C declines to give any statement until an interpreter is present. His lawyer documents the rights violation, undermining the credibility of the prosecution evidence.
Common Mistakes
- Signing without reading — Officers may write statements that do not match what the suspect actually said.
- Speaking without a lawyer — What you say may be misquoted and used against you.
- Believing promises like "tell the truth and you'll be released" — No officer has authority to make such promises.
- Not notifying family — Family cannot help arrange a lawyer in time.
- Confessing to something you did not do out of fear — Maintain the right to silence until counsel is present.
Frequently Asked Questions
What if I cannot afford a lawyer?
You have the right to request a state-appointed lawyer (through the Lawyers Council) in cases punishable by 5 or more years of imprisonment. For lesser cases, the Lawyers Council and university legal aid clinics offer initial consultations.
What if officers refuse to let me see a lawyer?
This is a legal violation. Family should report to the Royal Thai Police, the Human Rights Commission, or file a motion with the court.
Will my silence be interpreted as guilt?
No. Under Thai law, silence cannot be used as a basis for finding guilt.
Do suspects have the right to see the evidence before giving a statement?
During investigation, not always; in court, the defendant has the right to review all evidence and cross-examine witnesses.
Can I change lawyers during a case?
Yes. File a motion to substitute counsel, but it must not unduly delay the case.
Conclusion
Knowing your rights is the most important shield for any suspect. The core rule is simple: exercise the right to silence until your lawyer arrives. Never sign documents you have not read, and notify your family immediately. These rights exist to ensure fairness — using them properly and promptly protects your liberty and your ability to defend yourself effectively.
