Thailand's Department of Special Investigation has summoned Phuket MP Somchat Techathaworncharoen for questioning over allegations of B100 million in undeclared shareholdings held through nominee companies. The case has intensified debate about investigative transparency and due process protections for public officials under preliminary inquiry.
The investigation centers on a complaint filed August 9 alleging that Somchat—also known as Lawyer Keng—held shares in more than 30 Phuket-based companies suspected of acting as nominee entities for foreign nationals. These companies allegedly held land and condominium units worth over B100 million, potentially structured to circumvent Thailand's foreign business laws.
What the Investigation Alleges
According to Department of Business Development shareholder records, Somchat retained shares in four companies valued at approximately B9.08 million after leaving Parliament on December 12, 2025. These holdings were not reported to the National Anti-Corruption Commission (NACC), as required by asset declaration rules for MPs.
The complaint also references 12 additional companies where Somchat held shares during his parliamentary term, with a combined historical value of B102.88 million. When Somchat took office on February 25, 2023, he declared total assets of approximately B30 million to the NACC—a figure that sharply contradicts the shareholdings identified in business records.
Why Nominee Arrangements Matter in Thailand
The DSI (an agency responsible for investigating complex economic crimes) focuses on nominee structures because they circumvent Thailand's Foreign Business Act, which severely restricts foreign ownership of land and certain business sectors. Foreign nationals sometimes use Thai nominees—individuals holding shares or property on behalf of foreigners—to bypass these restrictions.
Companies proven to be nominee entities face dissolution, and individuals involved can face imprisonment and fines. For residents and property investors in Thailand, the case underscores serious risks. While such arrangements have been common workarounds for foreign buyers, authorities increasingly prosecute suspected violations. Foreign nationals involved risk losing investments entirely if companies are dissolved, while Thai nationals acting as nominees face criminal liability.
Opposition Raises Procedural Concerns
The People's Party, which holds Somchat's parliamentary seat, has challenged how the DSI is handling the inquiry. List-MP Karunpol Thiensuwan argued that publicly naming Somchat before formal charges were filed risks violating due process. Under Thai criminal law, suspects are presumed innocent until proven guilty, and the burden of proof rests entirely with prosecutors.
"Naming suspects before charges potentially prejudices public opinion and undermines the individual's rights," Karunpol contended, urging state agencies to safeguard confidential information during preliminary investigations. The criticism reflects broader concerns about investigative agencies balancing transparency with the presumption of innocence, particularly in cases involving elected officials.
The controversy echoes earlier DSI criticism when summoning another People's Party MP in a forex fraud probe that observers characterized as politically motivated.
Timeline and Current Status
The investigation has not yet been accepted as a special case under the Special Cases Investigation Act 2004. If the DSI finds evidence of criminal offenses outside its jurisdiction, the case will be referred to other agencies for prosecution. Thailand's House Committee on Police plans to brief lawmakers on the allegations and clarify whether special case status will be pursued.
MP Denies Allegations
Somchat has publicly denied all wrongdoing, maintaining that his business activities involve legitimate real estate investment and leasing with no Thai land transferred to foreigners through his companies. He has pledged full cooperation with the DSI investigation.
Broader Implications
The case highlights tensions between transparency and fairness in investigating public officials. While disclosure serves accountability, premature suspect naming before formal charges risks reputational harm without legal recourse. For Thailand's political landscape, it raises questions about whether investigative standards are applied uniformly or used selectively against opposition figures. The investigation's outcome will likely set precedents for how Thailand balances accountability with procedural protections in high-profile cases.
