The Constitutional Court will consider next Thursday whether it will accept for deliberation a petition regarding the renomination of Move Forward Party (MFP) leader Pita Limjaroenrat as prime minister, a source said.
The Ombudsman early this week asked the court to rule on Mr Pita's renomination rejection and to order parliament to postpone the next prime ministerial vote.
According to the Ombudsman, several complaints from both the public and members of parliament were made after MPs and senators rejected Mr Pita's renomination last week.
They claimed the rejection contravened the charter, and the Ombudsman decided to seek a judicial review and ask the court to postpone the prime ministerial vote to prevent any damage that would be difficult to fix.
However, another vote originally scheduled to take place today was postponed by parliament president Wan Muhamad Noor Matha pending the court's ruling.
Mr Wan said on Wednesday his decision to postpone the vote had nothing to do with Pheu Thai's attempt to secure support in parliament for one of its three prime ministerial candidates.
