The extraordinary parliamentary vote on Wednesday, which came after a final reading of the draft to amend the Constitution, saw 208 members voting for the amendment, four voting against, 94 abstaining and 136 choosing not to cast their votes.
The passing requirement was 369 votes, or half of the total votes in Parliament. The third reading of the draft was therefore rejected.
Of the 208 votes of approval, 206 came from members of the House of Representatives and two from senators. All four votes against the amendment came from senators.
Of the 94 who abstained, 10 are members of the House of Representatives and 84 are senators. Nine members of the House and 127 senators did not cast their votes.
Of the 250 senators, only two voted for the charter amendment – Naowarat Phongphaiboon and Phisal Manawaphat.
