Thailand's Constitutional Court on Wednesday rejected a petition seeking a ruling on the legitimacy of last month's parliamentary vote that blocked the renomination of the Move Forward Party leader as a prime ministerial candidate, public broadcaster Thai PBS said.

The court announced a unanimous decision on the ombudsman's petition to assess the constitutionality of parliament's refusal to reconsider Pita Limjaroenrat for the position of premier.

It ruled that the three petitioners, two Move Forward voters and one Move Forward MP, were not the people directly affected. The petitioners lacked direct influence, confirming the legitimacy of the parliament's decision.

In its petition, the Office of the Ombudsman had said it received 17 complaints objecting to parliament's decision to reject Pita’s renomination for prime minister, deeming it a violation of constitutional rights.

Meanwhile, the parliament decided to hold a second vote for the prime minister next week on Tuesday.
