The validity of the organic bill on MP elections will be decided on Wednesday by the Constitutional Court, with the National Legislative Assembly (NLA) confident of a favourable ruling by the judges.
Jate Siratharanont, a spokesman for the NLA whip, on Tuesday expressed confidence that the bill would be ruled legal by the court, with no clauses deemed unconstitutional.
The bill sailed through the NLA in March, but 27 members decided to petition the court to look into its legality after Prime Minister Prayut Chan-o-cha said he wanted to make sure that it would not violate the constitution - a move some suspected might be a ploy to further delay the general election.
The main concerns they cited were one clause that allows election staff or others to help disabled people cast their vote, and another that bars anyone who previously failed to vote in a national election without due cause from being appointed as a political office-holder.
Although the court may order some changes in the bill, Mr Jate said, the adjustments would not derail a plan to hold general elections in February next year.
The court ruled last Wednesday that another organic bill on the selection of senators was legal.
