Experience

  • Successfully defended a leading multinational electronics company against criminal charges alleging breach of agreements relating to employment conditions, collective bargaining agreements, and an award by advising the client on legal strategy, developing case strategy, and representing the client in court, with the court not allowing any of the plaintiff’s complaints to proceed further.
  • Defended a high-profile case in the Supreme Court Criminal Case Division for Persons Holding Political Positions by developing case strategy and representing the client in court, securing a historic best outcome for cases involving allegations of similar offenses.
  • Led defense counsel as supervising litigator and lead trial attorney in a complex criminal and civil case involving highly technical structural engineering issues, extensive documentary evidence, and multiple codefendants, guiding the team in managing all aspects of the defense, including cross-examination techniques and planning, written submissions, communications with the client and external parties, and liaising with the court and opposing parties.
  • Advised on a complex cross-border dispute between Thai and Taiwanese parties arising from an incident in Taiwan with parallel litigation proceedings in both jurisdictions, developed creative solutions to resolve the dispute, and successfully concluded a settlement agreement worth nearly THB 1 billion (approx. USD 30 million), saving the parties substantial litigation costs that would have been incurred from pursuing cases in courts across two jurisdictions.
  • Led the defense in a complex, highly technical dispute arising from maintenance works at a biochemistry facility operated by the Thai subsidiary of a global filtration and purification company against claims for alleged damage to stainless-steel systems, which entailed developing technical case strategy, exposing methodological flaws in opposing expert analysis, and dismantling the plaintiffs’ causation theory through focused cross-examination and targeted impeachment, resulting in complete dismissal at first instance following a five-day evidentiary trial.
  • Successfully represented a global sports management company in a complex international commercial dispute arising from default payments for services related to global golf tournaments, which included developing and executing a comprehensive litigation strategy and facing a multibillion-baht counterclaim alleging breach of contract and wrongful acts, resulting in a favorable judgment with the court ordering payment plus interest and dismissing the counterclaim in its entirety.
  • Led a comprehensive corporate fraud cleanup and operational reset for a multinational client’s local subsidiary, serving as the sole on-the-ground adviser. This involved addressing acute governance gaps by designing and executing a structured transition program that stabilized operations and protected enterprise value; managing senior leadership separation, workforce morale and retention, and implementation of communication protocols; coordinating asset recovery; supervising secure network shutdowns; and overseeing preservation of critical documents and data. Close coordination with corporate teams to redesign corporate architecture, adjust shareholdings, and align governance frameworks, ensuring legal and HR compliance throughout, allowed the company to return to stability under a renewed operating model with strengthened controls.
  • Defended a multinational electronics company against false claims in connection with a subcontractor that failed to deliver work as agreed upon in a construction agreement.
  • Advised on case strategy in relation to an ongoing contentious estate division dispute involving heirs in multiple jurisdictions in Southeast Asia.
  • Advised high-profile individuals on prenuptial agreements, family constitutions, and wills to prevent issues among future heirs.
  • Advised various multinational companies on draft agreements containing multitier dispute resolution clauses concerning negotiation, mediation, and arbitration.
  • Advised a multinational company on its online multilevel marketing business in relation to various legal concerns, including potential criminal liabilities.
  • Defended directors and employees against criminal charges in relation to forgery and false documents by proposing and executing legal strategy, advising clients at inquiry meetings with related authorities, and getting warrants revoked in an ongoing investigation process.
  • Prosecuted and defended high-profile and highly contentious divorce cases—both single- and multijurisdictional—navigating complex and emotionally charged family dynamics to achieve favorable settlements by identifying and leveraging legal issues overlooked by opposing parties, and provided postdivorce transitional counsel.
  • Represented a multinational cosmetics company in the witness examination process and succeeded in enforcing a noncompete agreement and securing damages for a breach of the agreement.
  • Represented over 10 international insurance companies in multibillion-baht claims regarding product liability and wrongful acts, and won challenges on choice of court with jurisdiction over the case.
  • Advised on drafting a petition to the Criminal Court for Corruption and Misconduct Cases to request that the matter be considered by the Constitutional Court; the court granted the request without delay.

Thailand has expanded the mandatory use of the Electronic Government Procurement (e-GP) system to cover submissions of procurement appeals to all government agencies subject to the Public Procurement and Supplies Administrative Act B.E. 2560 (2017) (Government Procurement Act). The expansion, which was set out in an official circular dated September 16, 2026, from the Public Procurement and Supplies Administrative Ruling Committee, takes effect on October 1, 2026. Notable Changes Under the expanded framework, bidders challenging an e-bidding or selective-method procurement result must file their appeal exclusively through e-GP within seven working days of the result being announced by the Comptroller General’s Department. While the system accepts filings around the clock during that window, submissions on the final day must be fully completed by 16:30 according to the e-GP system clock—merely starting a draft or uploading materials before the cutoff does not count as a confirmed submission. Government agencies that disagree with an appeal, in whole or in part, will also report their findings and supporting documents to the Appeals Committee through e-GP using the prescribed Appeal Opinion Report, also within seven working days of receipt. Withdrawals of appeals must likewise follow prescribed e-GP steps that vary depending on whether the matter is still under agency review, has been forwarded to the Appeals Committee, or has already been resolved. Excluded Categories Certain categories of procurement are not subject to the new guidelines on filing appeals electronically. These include: Procurement of supplies for confidential government use. Procurement conducted by government agencies operating overseas where the bidder is a foreign legal entity with no legal representative in Thailand, or where the bidder is a non-Thai national. Consulting service procurement under chapter 7 of the Government Procurement Act Design or construction supervision procurement under chapter 8 of the Government Procurement These exclusions apply

Arbitrator independence and impartiality form the cornerstone of a legitimate arbitral process. Under section 19 of the Thai Arbitration Act B.E. 2545 (2002), prospective arbitrators must disclose circumstances likely to give rise to justifiable doubts as to their impartiality or independence, and existing arbitrators must do so throughout proceedings. This mirrors article 12 of the UNCITRAL Model Law. Yet despite this clear mandate, practical implementation varies significantly across Thailand’s arbitration landscape. Background Thailand’s two principal arbitration institutions, the Thai Arbitration Institute (TAI) and the Thailand Arbitration Center (THAC), both maintain procedures for addressing arbitrator challenges and require compliance with the statutory disclosure obligation. Under both sets of rules, any party wishing to challenge an arbitrator must submit a challenge application within fifteen days of becoming aware of the relevant facts, and a committee is appointed to consider the matter on a case-by-case basis. The TAI additionally prescribes its Code of Ethics and Conduct for Arbitrators to further emphasize the expectation of impartiality and transparency. However, Thailand’s arbitration ecosystem extends well beyond the TAI and THAC. Several sector-specific institutions also administer arbitral proceedings, including the Thai Commercial Arbitration Office under the Board of Trade of Thailand, the Arbitration Centre of the Office of the Insurance Commission, the Arbitration Centre of the Securities and Exchange Commission, the Office for the Prevention and Resolution of Disputes regarding Intellectual Property, and the Arbitration Centre of the Thai General Insurance Association. These institutions each operate under their own procedural rules, which were developed to serve particular industries and dispute profiles. The procedural mechanisms for securing and documenting an independence declaration are not uniformly established across these forums. Consequences of Procedural Inconsistency This creates a notable gap. Not all arbitration bodies have a formalized procedure requiring written independence statements before proceedings commence. Some tribunals proceed
