The controversial approval of legislation allowing all nine members of National Anti-Corruption Commission to remain in office is likely to be challenged in the Constitutional Court by disgruntled members of the National Legislative Assembly.
NLA member Thawisak Sutkawathin said on Wednesday he expected enough colleagues who disagree with the bill approved by a majority of NLA members, allowing incumbent NACC members to stay in office, would finish signing their names to the petition by the day's end.
This would pave the way for it to be submitted to the court.
They were not going to ask the court for a ruling as NLA members who lost during the recent vote for the bill. "This will be a petition from the NLA itself," Mr Thawisak.
By regulation this requires that at least 10% of the 250 NLA members sign it. He expected to have the 25 signatures of support by later in the day.
The group disagrees with Section 178 of the legislation, which concerns the qualifications of members of the anti-corruption agency. The current NACC panel will not be "reset" despite arguments that the qualifications of some members fall short of those set down in the 2017 constitution.
The new charter bans commissioners from having served in a political position.
