A second summons from Thailand’s Department of Special Investigation (DSI) has reached Somchat Techathaworncharoen, the People’s Party MP for Phuket Constituency 1, and DSI has set September 7, 2026 as the date for him to appear before investigators. Justice Minister Pol Lt Gen Rutthaphon Naowarat confirmed the development on September 2, saying investigators had found evidence that Somchat served as a director and shareholder in private companies that hold real estate and condominium units in Phuket together with foreign nationals, Thairath reported the same day. This is a continuation of the case reported on August 21, when DSI had opened an investigation but had not yet issued any summons. What is new: DSI has now moved to the summons stage, a first attempt at delivery failed, and an appearance date is set. No charge has been filed, no court or prosecutor has ruled on the underlying nominee allegation, and Somchat denies it.
What happened
DSI issued a first summons to Somchat around August 22, but Thailand’s postal service reported the address as closed and could not complete delivery, Dailynews reported; the same August 31 report said DSI was preparing to issue a second summons as a result. Thairath and Thaipost, both reporting on September 2, said DSI had in fact issued that second summons on August 31, that the postal service had since confirmed it reached Somchat, and that DSI had set September 7 as the date for him to appear. Minister Rutthaphon said DSI does not yet know whether Somchat will actually appear on that date — only that delivery of the summons itself has been confirmed, according to Thairath.
Bangkok Post, reporting independently in English, says DSI expects Somchat to provide company registration documents, details of the companies’ management structure, his financial records, and an account of the source and purpose of money transfers connected to the companies. A DSI source cited by Bangkok Post said officials had found evidence that Somchat is a shareholder in companies that own condominium units and properties in Phuket in partnership with foreigners.
Somchat has denied evading the first summons. He told reporters he received no document and no one contacted him about it, and that he is ready to go to DSI at any time, even without a formal appointment, to clarify the matter and show his good faith, Dailynews reported. Minister Rutthaphon said on August 28 that DSI’s pursuit of the case is not persecution of an MP, and that if a sitting MP had in fact broken the law, the greater damage would be to the country, according to The Standard.
Background: how the case reached this point
The allegation traces to a complaint that political activist Ruangkrai Leekitwattana filed with a government complaints centre on August 9, asking that Somchat’s shareholdings be examined for whether the shares were genuinely paid for, where the money came from, and whether the companies operate lawfully, Thaiger reported. The August 21 report covered the allegation’s first week: Somchat volunteering to meet DSI before any summons existed, and People’s Party deputy leader Rangsiman Rome saying the party would not shield him if the nominee allegation is confirmed, while also criticising DSI for letting his name circulate before a summons was issued. That criticism is now overtaken by events — a summons has since been issued twice.
No DSI case file or summons document has been published, and no source reports whether DSI has formally accepted the matter as a special case. This account relies on the justice minister’s September 2 public confirmation, reported by Thairath and Thaipost together with the September 7 appearance date, on Dailynews’s August 31 report that a second summons was being prepared, on Bangkok Post’s independent report of DSI’s document requests, and on The Standard’s earlier, August 28 report of the minister’s remarks on the case.
Who is affected
Directly, this remains a matter concerning one sitting MP and the companies in which he is reported to hold a director’s or shareholder’s stake. DSI’s document requests in this investigation — company registration papers, management-structure details, financial records, and the source and purpose of money transfers — cover similar ground to what DBD’s Order 2/2569 requires, though that rule is narrower and separate: it applies prospectively to new company registrations and amendments involving foreign participation or a foreign signatory, covered here, not to an active DSI investigation of an existing company. Anyone now registering or amending a Thai company with a foreign shareholder or signatory falls under that DBD filing rule; anyone holding Phuket property through an existing Thai company structure can see in this case the kind of documentation DSI asks for when a structure is examined, which is a different and later-stage form of scrutiny.
What it may mean for Phuket property
This update does not change the underlying legal test set out on August 21: a Thai company with a foreign stake at or under 49% is a legal structure, not itself proof of a nominee arrangement, and the test is whether a Thai majority holder is holding shares for a foreigner’s capital, control and economic benefit. What this case now shows in practice is what DSI asks for when it tests that question against a real company — registration documents, management records, financial statements and a documented explanation for money transfers. An owner or buyer holding Phuket property through a similar Thai company structure can expect the same kind of documentation request if that structure is ever examined, which is a practical reason to keep clean, contemporaneous records of capital contributions and fund transfers rather than a reason to avoid the structure itself.
What remains unknown
Whether DSI has accepted the case as a special case, and on what legal basis, is unreported. No DSI case file or company list has been published, so the company count reported around this case cannot be checked against a primary register extract. Which specific Phuket properties the companies hold, and their individual values, remain unreported beyond the general description of real estate and condominium units. Whether Somchat will in fact appear on September 7 is itself unknown — DSI’s own minister said only that the summons was confirmed delivered, not that Somchat’s attendance was. Whether he will provide the documents DSI is seeking, and what happens at or after any appearance, is also unknown as of publication. Whether the separate asset-declaration question raised earlier in the case has been referred to the National Anti-Corruption Commission, and with what result, is also unreported.
