Experience

  • Advised a leading multinational pharmaceutical company on conducting an anticorruption compliance audit in its Thai subsidiary. Prior to the audit we provided advice to the client and its U.S.-based global anticorruption counsel on Thai anticorruption law and compliance issues in the Thai healthcare industry. After the audit, we reviewed relevant interview notes to identify potential red flags and areas for compliance enhancement.
  • Representing a world-leading manufacturer in a USD 200+ million global fraud case involving former employees in the company’s Thai operations. Among other things, we conducted employee investigations and interviews, advised on termination of employees, and liaised with the Crime Suppression Division of the Royal Thai Police, various embassies, the Anti-Money Laundering Office, and similar offices in other jurisdictions around the world.
  • Prepared anticorruption, anti-money laundering, and unfair competition compliance policies for a multinational corporation with operations in over 100 countries, including countries with extraterritorial anticorruption laws such as the FCPA. We also advised on the implementation of our client’s compliance program in Thailand, which involved tailoring our client’s global compliance concerns to the local Thai jurisdiction.
  • Worked with a leading multinational law firm, and acted as local counsel on an internal corporate anticorruption investigation at the Thai subsidiary of a global beverage manufacturer. We assisted the client in interviewing employees to gather crucial information, reviewed evidence, and advised on various issues of Thai law, including anticorruption, tax matters, property, and regulatory licenses, among others, to help the client identify if alleged bribes actually took place.
  • Assisted an industry-leading provider of computer storage technologies and solutions, with an internal investigation and review of claimed wrongdoing by a senior-level Thai administrative employee. We conducted a thorough review of preliminary investigative reports to assist in our conduct of on-the-ground employee interviews and assessments, and provided detailed summaries and reporting of our investigative findings and advice on Thai law.
  • Acted for the Thai subsidiary of a multinational plate glass manufacturer in a high-stakes criminal investigation by Thailand’s Department of Special Investigation (DSI) for allegedly purchasing black market minerals for use by its manufacturing facility.
  • Assisted a multinational project management company in conducting an internal investigation involving bid rigging on energy and infrastructure projects in Thailand and across Southeast Asia. Our investigations uncovered significant wrongdoing by an employee, which motivated the client to revamp their internal policies to avoid similar situations in the future.
  • Advised several pharmaceutical companies on anticorruption regulations related to their business dealings and procurement contracts with Thai government hospitals.
  • Advised a global food and beverage company on an extensive internal anticorruption investigation in Thailand.
  • Assisted a multinational energy services company on an internal bid-rigging investigation in Thailand.

The Thai cabinet has approved a draft amendment of the Emergency Decree on Measures for the Prevention and Suppression of Technological Crimes as proposed by the Ministry of Digital Economy and Society to strengthen measures against technological crimes, particularly targeting call center scams and cyber fraud. Following the Council of State’s review, the emergency decree will be become effective immediately upon its enactment and publication in the Government Gazette. While the draft amendment is not yet publicly available, the government recently indicated that the emergency decree aims to empower authorities with decisive measures to combat cybercrime effectively. It underscores the shared responsibility among various sectors, including banking, telecommunications, and online platforms, in safeguarding against technological crimes. Key provisions of the draft amendment of the emergency decree include: Telecommunications provider obligations: Telecommunications service providers must suspend SIM cards associated with criminal activities. The National Broadcasting and Telecommunications Commission and mobile service providers themselves are authorized to temporarily suspend mobile phone numbers if there is reasonable suspicion of involvement in criminal activities. Banking responsibilities: Financial institutions are required to promptly report mule accounts to the Anti-Money Laundering Office to facilitate quick restitution to victims. The Anti-Money Laundering Transaction Committee is empowered to order the return of funds to victims without requiring a final court ruling. Penalties for noncompliance: The amended emergency decree introduces penalties for noncompliance by regulated entities that fail to prevent criminal activities for offenses related to technology crimes in the following cases: Digital asset services: Those engaged in the buying, selling, or exchanging of digital assets, such as cryptocurrencies and digital tokens, as well as digital asset businesses that launder money obtained from online crimes by converting it into digital currency, will be subject to imprisonment for up to one year, a fine of up to THB 100,000,

On October 16, 2024, Thailand’s Anti-Corruption Cooperation Committee (ACCC) issued a notification to enhance anticorruption standards in public procurement. The new notification (officially “Notification of the Anti-Corruption Cooperation Committee on the Procurement Budget and Minimum Standards of the Policy and Directions for Anticorruption in Relation to Procurement according to Section 19 of the Public Procurement and Supplies Administration Act B.E. 2560”) supersedes previous guidelines and imposes stricter compliance requirements on business entities involved in the government procurement processes. The updates not only align with the goals of Thailand’s Public Procurement and Supplies Administration Act B.E. 2560 (2017) but also reflect the government’s resolution to mitigate corruption, particularly in high-value public contracts. The ACCC’s new notification introduces additional definitions, lowers budget thresholds for compliance, and strengthens business obligations. Key Components The new notification continues the previous guidelines’ requirement that businesses seeking to bid on government procurement projects meet the specified minimum standards—such as communicating and implementing anticorruption policies at all organizational levels, establishing a code of conduct, and providing related training programs to employees. The notification also introduces a number of changes, the most notable of which are detailed below. “Entrepreneur” definition. The definition of this term is narrowed to entities involved in the public procurement bidding process. Previously, the definition broadly applied to all business entities engaged in selling goods or services. Threshold for mandatory compliance. The project budget threshold that necessitates compliance with the minimum standards is  THB 300 million—a reduction from the previous threshold of THB 500 million. Minimum standards to prevent unfair competition. The new notification introduces a specific definition for “disturbing fair competition,” establishing clear parameters around actions that disrupt competitive fairness within public procurement. Continued compliance requirements. Businesses’ compliance with the minimum standards must now extend from the date of bid submission to the
