On May 17, reporters revealed that the Election Commission (EC) and the Department of Special Investigation (DSI) issued summonses for 55 senators to clarify allegations of collusion in the 2024 Senate election. These summonses are scheduled between May 19–21 at the EC Office in Chaeng Watthana Government Complex.
On May 19, 22 senators are scheduled to appear, including Gen. Kriangkrai Srirak (First Vice President of the Senate), Veerasak Vijitsaengsri, Mongkol Surasajja (Senate President), Pol. Lt. Gen. Boonchan Nuansai, Alongkot Vorakee, and Cheewapap Cheewathum. On May 20, another 22 are expected, such as Pol. Maj. Gen. Chatwattana Saengphet, Sompan Palasak, and Pol. Lt. Col. Sanga Songmahachai. The final group of 11, including Chokchai Kittithanesuan, will appear on May 21.
Mr. Sawang Boonmee, Secretary-General of the EC, said the investigation is still in the initial review phase, focusing on complaints related to the election. There are four steps in the process, and it is currently at the first stage. The investigative committee must complete the process within one year from the announcement of the election results, which was made on July 10, 2024—meaning the deadline is July 9, 2025.
He clarified that the one-year timeframe is an internal procedural benchmark to ensure transparency, not a rigid deadline that compromises independent justice. The investigation will not be interfered with by EC officials, and the gathering of evidence remains neutral and independent.
Mr. Sawang also noted that the selection of senators is complex, involving district, provincial, and national levels with inter-group voting, which complicates the evidence collection. Despite these challenges, the EC is committed to following legal procedures and court rulings. He believes clarity will emerge soon as the investigative committee is working on completing the process within the scheduled timeframe.
