Thawee warns the Election Commission is “not a court” as pressure mounts to send the Senate collusion probe to the Supreme Court. More than 229 politicians are under scrutiny in one of Thailand’s biggest political corruption investigations.
Thailand’s biggest political corruption investigation in years has reached a defining moment as former Justice Minister Police Colonel Thawee Sodsong urges the Election Commission to send the explosive Senate collusion case directly to the Supreme Court, insisting that an 80,000-page file and “credible evidence” are all the law requires. With more than 229 politicians under scrutiny, allegations of organised vote fixing, money laundering and conflicts of interest engulfing the 2024 Senate election, and the Constitutional Court’s ruling now at the centre of the battle, the Commission’s next decision could become one of the most consequential tests yet of Thailand’s electoral system, independent institutions and the rule of law.
Thailand’s deepening Senate election crisis entered a decisive new phase this week as former Justice Minister and Prachachart Party leader Police Colonel Thawee Sodsong urged the Election Commission (EC) to refer its investigation directly to the Supreme Court.
He argued that the law requires only “credible evidence,” not proof beyond reasonable doubt. More than 229 people are under scrutiny, including senators, MPs and political party executives. The Commission’s decision is now expected to shape confidence in Thailand’s electoral system, independent agencies and the rule of law.
Writing on Facebook on July 30, Thawee described the case as historic. He said it would test both the credibility of independent organisations and public faith in constitutional processes. He repeatedly cited Constitutional Court Ruling No. 1/2569. According to Thawee, the Commission must remember its constitutional role.
“The Election Commission is not a court,” he wrote. Its responsibility, he argued, is to decide whether sufficient credible evidence exists before forwarding the case for judicial determination.
Thawee says Election Commission must send Senate collusion case to court once credible evidence exists
The investigation centres on allegations that the June 2024 Senate election was manipulated through organised collusion, vote fixing and money laundering.
What initially appeared to be an electoral dispute has since become one of Thailand’s most significant constitutional and criminal investigations since the 2014 military coup. The controversy now reaches beyond the Senate itself. It also involves the Election Commission, the Department of Special Investigation (DSI), the Constitutional Court and senior political figures.
The Senate election was conducted under the 2017 Constitution and the Organic Act on the Acquisition of Senate Members B.E. 2561 (2018). Candidates advanced through multiple rounds of indirect voting among themselves.
However, critics questioned the process almost immediately. They argued that the complicated voting structure created opportunities for coordinated voting. Soon afterwards, unsuccessful candidates and civil society groups alleged that organised voting blocs and pre-arranged candidate lists had influenced the final outcome.
DSI special case transformed Senate election allegations into one of Thailand’s biggest political crises
Those allegations gathered momentum in early 2025 when Thawee, then serving as Minister of Justice, referred the matter to the Department of Special Investigation.
Acting on complaints and documentary evidence, he sought a criminal investigation alongside the Election Commission’s inquiry. Rather than focusing solely on election offences, the DSI examined whether the alleged collusion involved organised crime, money laundering and financial conspiracy. Those offences fall within its statutory jurisdiction as special cases.
That decision immediately intensified political tensions. Under Thai law, the DSI cannot assume jurisdiction over politically sensitive matters automatically.
Instead, the case first required approval from the agency’s 21-member Special Cases Committee. After weeks of political pressure and extensive public debate, the committee voted to accept the investigation. That decision marked a turning point. An electoral dispute had become a major criminal investigation involving several state institutions.
Throughout the investigation, Thawee consistently rejected claims that the DSI had encroached upon the Election Commission’s constitutional authority. Instead, he maintained that election offences and criminal offences are separate legal questions.
DSI probe expanded as ethics complaints failed and Constitutional Court backed ministers’ conduct
Allegations involving money laundering, conspiracy and organised financial activity, he argued, belonged squarely within the DSI’s mandate. Meanwhile, investigators gathered evidence from thousands of witnesses and examined financial transactions involving hundreds of individuals. Reports later suggested that as many as 1,200 people could ultimately come under investigation.
In parallel, the Election Commission continued pursuing its own inquiry into alleged Senate election collusion. The simultaneous investigations created an unprecedented overlap between criminal law and electoral regulation.
Political tensions escalated further when senators filed ethics complaints against Thawee and Deputy Prime Minister Phumtham Wechayachai.
They accused both ministers of abusing executive authority through their involvement in the DSI investigation. The Constitutional Court later dismissed those complaints, ruling that neither minister had breached constitutional ethics through their actions or public statements.
Against that backdrop, Thawee devoted much of his latest statement to the legal threshold governing the Commission’s decision. He argued that Constitutional Court Ruling No. 1/2569 clearly defines the Commission’s responsibilities. According to Thawee, the EC is not responsible for deciding guilt or innocence.
Constitutional Court ruling says Supreme Court alone decides guilt after Election Commission finds evidence
Instead, it must determine only whether credible evidence exists to justify referring the matter to the Supreme Court. He warned against applying criminal standards of proof at this stage because that responsibility belongs exclusively to the judiciary.
To support that argument, Thawee relied on Section 62 of the Organic Act on the Acquisition of Senate Membership. The law states that where there is credible evidence suggesting an election was not conducted honestly or fairly, the Election Commission shall submit a petition to the Supreme Court.
Notably, Thawee argued that Constitutional Court Ruling No. 1/2569 reinforces that interpretation. He said the judgment referred directly to parliamentary records explaining the legislative intent behind the provision.
According to those records, lawmakers deliberately adopted a public law standard rather than the criminal standard requiring proof beyond reasonable doubt. Consequently, the Commission’s task is limited.
It must determine whether credible evidence exists. The Supreme Court alone decides whether offences have actually been committed. Thawee stressed that the Commission should not substitute its judgment for that of the court.
Thawee says 80,000-page case file easily clears the legal threshold for Supreme Court consideration
He also compared Section 62 with Section 66 of Thailand’s Criminal Procedure Code. Under that provision, courts may issue arrest warrants based on reasonable evidence alone. Thawee argued that the threshold under Section 62 is no higher.
Therefore, once credible preliminary evidence exists, the Commission should refer the matter without attempting to resolve every disputed fact.
As part of his argument, Thawee referred to reports that the investigation file now exceeds 80,000 pages. According to those reports, investigators have assembled documentary evidence, forensic material, financial records and supporting information.
He argued that the size of the case file demonstrates the scale of the investigation. More importantly, he said the legal question remains unchanged. The issue is whether the statutory threshold has been satisfied, not whether guilt has already been conclusively established.
Separately, Thawee outlined several issues that he said continue to undermine public confidence in the Commission’s handling of the case. His first concern involved the appointment of Election Commissioners. He noted that while 138 senators were themselves under investigation for alleged election fraud, many of those same senators later voted to approve five of the Commission’s seven members.
Thawee questions commissioner approvals and conflicts of interest involving senators under investigation
Although Election Commissioner Thitichat Nuchanat’s term has expired, he continues serving because the Senate has not approved a successor.
Meanwhile, Commissioners Narong Klanwarin, Anan Suwannarat, Narong Rakroi and Jirutt Visaljit all received approval from the current Senate. Thawee argued that those circumstances naturally raise questions about perceived conflicts of interest. Even without proven wrongdoing, he said public confidence could still suffer.
On another front, Thawee identified several procedural issues that continue attracting public scrutiny. One concerns Election Commission Regulation 122.
The regulation requires candidates to retain the same candidate number during both morning and afternoon voting rounds. Critics argue that requirement could facilitate coordinated voting or vote fixing. They also contend that it weakens the principle of secret balloting protected under Section 33.
He also highlighted voting patterns from the Senate election itself. Among the 138 successful senators, many reportedly received clustered vote totals between 50 and 79 votes. By contrast, many unsuccessful candidates received only between 20 and 28 votes. Critics argue those figures are consistent with organised vote allocation rather than independent voting behaviour.

In addition, Thawee questioned the appointment of Subcommittee No. 36 to consider dismissing complaints even though Subcommittee No. 26 conducted the original investigation.
He also referred to reports that the Election Commission secretary-general’s performance assessment had been revised from “fail” to “pass.” Finally, he criticised the Commission’s refusal to accept investigation files from the DSI despite claims that they contained financial evidence and other supporting material.

In response to those concerns, Thawee argued that each issue requires a clear and transparent explanation. He said public confidence depends upon openness throughout the process. He also argued that public law principles require every state agency to place the public interest above personal interests while maintaining confidence in the justice system.
Accordingly, Thawee urged the Election Commission to exercise its powers under Section 62 and submit the complete case to the Supreme Court. He stressed that doing so would not amount to a finding of guilt.
Instead, it would allow the constitutional legal process to proceed exactly as Parliament intended. Thawee concluded by saying Thai society now requires a judgment based solely on facts and the law. He said the Senate collusion investigation has become a defining test of the rule of law, the credibility of Thailand’s independent organisations and public confidence in the country’s electoral system.
