The Constitutional Court on Wednesday threw out a complaint about the failure of Prime Minister Prayut Chan-o-cha and his cabinet ministers to recite the complete oath of office.
The court voted unanimously that it had no authority to consider issues between the administrative branch and the monarchy.
The complaint was lodged by Panupong Churak, a Ramkhamhaeng University student, to the Ombudsman on Aug 20. Mr Panupong argued the incomplete oath by the prime minister affected his rights under the constitution. Section 213 provides for a complaint by someone who believes their constitutional rights were violated.
Gen Prayut took the oath before His Majesty the King on July 16. The prime minister failed to complete the oath as he omitted the final sentence during the swearing-in. The opposition will grill him on the issue during a general debate on the issue on Sept 18.
On Aug 27, the King summoned Gen Prayut and all cabinet members to receive a message, in which His Majesty gave them moral support and asked the government to perform its duty as pledged in the oath of allegiance.
The court on Wednesday also threw out a petition by a former member of the dissolved Thai Raksa Chart Party, Ruangkrai Leekitwattana, on the same issue.
