Understanding Criminal Accusation and Criminal Complaint in Thai Law: Key Differences and Legal Implications

 

Introduction: 

What Is a Criminal Accusation and Criminal Complaint?

In Thailand’s criminal justice system, individuals often encounter two legal concepts that may appear similar: criminal accusation and criminal complaint. However, under Thai law, they serve distinct purposes and follow different procedural paths. Understanding the legal difference between an accusation and a complaint is crucial for both legal professionals and citizens wishing to take lawful action.

This article explores the legal definitions, procedural requirements, and implications of criminal accusation and criminal complaint under Thai law, providing practical examples and guidance on how to properly initiate each process. These distinctions are particularly important in ensuring that legal proceedings are valid and recognized by investigating authorities. For complex cases, seeking guidance from a lead law firm in Bangkok is highly recommended.

What Is a Criminal Accusation?
Definition and Legal Standing

A criminal accusation is the act of informing law enforcement authorities—particularly an investigating officer or inquiry officer—that a criminal offense has been committed. Importantly, the accuser does not need to be the victim of the crime. Any member of the public may file an accusation if they have reason to believe that a public criminal offense has occurred.

Common Examples of Accusers:

• Concerned neighbors

• Government officers

• Whistleblowers

• NGOs and anti-corruption watchdogs

• Witnesses or co-defendants

Legal Effect

A valid criminal accusation enables the police or investigative body to commence a formal investigation. In cases involving public offenses (e.g., drug trafficking, illegal gambling, homicide), the state is empowered to act independently based on the accusation.

For official guidance on Thai criminal procedure, see the Criminal Procedure Code of Thailand (EN).

How Is It Different from a Criminal Complaint?

Key Legal Distinctions

Criteria	Criminal Accusation	Criminal Complaint
Who can file	Any person	Only the victim of the crime
Applicable cases	Public criminal offenses only	Both public and private criminal offenses
Withdrawal	Not withdrawable (not filed by victim)	Withdrawable in compoundable cases
Legal necessity	Triggers investigation by police	Mandatory in compoundable offenses

Legal Consequences

If a crime is compoundable (e.g., defamation, minor assault), a complaint from the victim is legally required to prosecute the case. In contrast, a criminal accusation may suffice in public crimes where the state has an independent duty to pursue prosecution.

Filing a Valid Criminal Accusation

Step-by-Step Legal Requirements:

1. Provide detailed factual circumstances — who did what, where, when, and how.

2. Identify the alleged offender, if possible — or at least describe the individual or incident.

3. Submit the accusation either verbally or in writing to an inquiry officer.

4. Sign the document or verbal statement — unsigned accusations carry no legal effect.

5. Ensure submission is made directly to an authorized investigating officer under the Criminal Procedure Code.

Failure to comply with any of these steps may result in the matter being dismissed as a mere diary entry, not a legally actionable case.

Common Pitfalls and Legal Invalidity

• Lack of identity of the accuser

• No signature on the statement

• Vague or speculative factual account

• Statement made to non-investigating personnel (e.g., administrative staff or social media)

Such deficiencies will prevent the case from being formally opened or prosecuted.

Practical Examples in Thailand

Frequent Scenarios Where Criminal Accusation Applies:

1. Government officials discover illegal gambling and file accusations.

2. NGOs file accusations in corruption or fraud cases.

3. Members of the public report criminal behavior in their neighborhood.

4. A defendant turns state witness and accuses a co-offender.

5. Activist groups submit evidence of human rights violations.

In all these scenarios, the law permits parties who are not directly harmed to initiate criminal procedures in the public interest.

What to Do If You Witness a Crime

To make a legally effective accusation:

• Avoid social media exposure or informal channels.

• Go directly to the police station and ask for the inquiry officer on duty.

• Provide all relevant documents, photographs, or recordings.

• Retain a copy of the police record for follow-up.

Conclusion: Know the Right Legal Tool for the Right Purpose

Understanding the difference between criminal accusation and criminal complaint helps ensure that your actions are legally valid and actionable. While accusations can be made by anyone, complaints require victim status and have specific legal consequences in compoundable cases.

In all instances, accuracy, detail, and proper procedure are essential to trigger the legal process effectively. For guidance or to initiate a criminal procedure properly, consult a licensed attorney or contact a lead law firm in Bangkok experienced in Thai criminal law.
