Preliminary Hearing in Thailand:
A Comprehensive Guide by a Lead Law Firm in Bangkok

In Thailand’s criminal justice system, the preliminary hearing—known locally as the inquiry into the merit of the complaint—serves as a crucial safeguard against unfounded criminal prosecutions. This process ensures that only cases with sufficient merit proceed to trial, thereby protecting individuals from baseless legal actions.
As a lead law firm in Bangkok, we provide an in-depth overview of the preliminary hearing process in Thailand, its legal foundations, procedures, and strategic considerations for both complainants and defendants.
Understanding the Preliminary Hearing in Thailand
A preliminary hearing in Thailand is a judicial process conducted when a private individual initiates a criminal complaint. The court evaluates whether the complaint has sufficient merit to proceed to trial. This step is mandated by the Thai Criminal Procedure Code to prevent frivolous or malicious prosecutions.
For a detailed understanding of Thailand’s criminal procedure, refer to the Criminal Procedure Code provided by the International Commission of Jurists.International Commission of Jurists
Legal Basis for Preliminary Hearings
The legal framework for preliminary hearings is established under Sections 162 and 165 of the Thai Criminal Procedure Code. These sections stipulate that when a private individual files a criminal complaint, the court must conduct a preliminary inquiry to determine if there is a prima facie case against the accused.
This process aligns with Thailand’s commitment to the principle of “innocent until proven guilty,” ensuring that defendants are not subjected to unwarranted legal proceedings.
When is a Preliminary Hearing Required?
A preliminary hearing is mandatory in cases where a private individual, rather than a public prosecutor, files a criminal complaint. Common scenarios include allegations of defamation, minor assaults, or property disputes.
Conversely, if the complaint is filed by a public prosecutor, the case proceeds directly to trial without the need for a preliminary hearing.
The Preliminary Hearing Process
Filing the Complaint
The complainant must submit a detailed complaint outlining the alleged offense, supported by relevant evidence such as documents, witness statements, or other pertinent materials.
Court Evaluation
The court reviews the submitted evidence to ascertain whether there is sufficient merit to proceed. This evaluation focuses on the credibility and relevance of the evidence presented.
Rights of the Accused
During the preliminary hearing, the accused has the right to legal representation. While the accused’s presence is not mandatory, their legal counsel can cross-examine witnesses and challenge the evidence presented.
Possible Outcomes of a Preliminary Hearing
Case Accepted
If the court determines that the complaint has merit, the case proceeds to trial. The court will issue a summons or arrest warrant, and the trial process commences.
Case Dismissed
If the court finds the complaint lacks sufficient merit, it will dismiss the case. However, the complainant has the right to appeal this decision within a specified timeframe.Go Law Phuket
