Following the 14 May 2023 general election to elect members of the House of Representatives, the Election Commission of Thailand (ECT) has already announced unofficial results of the election. If voters or candidates believe that the election results were unfair, they are allowed to file objections to the ECT within 30 days after the election day.
The ECT will investigate cases of election fraud. If there are no complaints about violations in election laws, the ECT will certify results of the general election within 60 days, or by 13 July, following the election day.
Then, by 27 July, the first parliamentary session will be held for members of the House of Representatives to elect the Speaker of the House of Representatives and his deputies, as the law requires that a parliamentary session be called within 15 days after the ECT certifies results of the general election.
In August, the House Speaker will call a session of the National Assembly, comprising 500 members of the House of Representatives and 250 senators, for the nomination of a person suitable for serving as prime minister.
The resolution of the National Assembly approving the appointment of the prime minister requires more than half of the combined votes, or 376, from both the House of Representatives and the Senate. It must be passed by an open vote. The House Speaker will countersign the Royal Command appointing the new prime minister.
After the appointment of the prime minister is endorsed by His Majesty the King, the new prime minister is expected to appoint members of the Cabinet in the middle of August. The new Cabinet members will have to be sworn in before His Majesty the King before assuming office. The existing government will remain in office until the new Cabinet assumes office.
