General Somjet Boonthanom, chair of the committee under the National Legislative Assembly said the tripartite law review committee met following the objection to the point by the Constitution Drafting Commission, which had drafted the law before it was passed by the NLA.
They agreed that the point would trigger a new problem concerning fraud in areas where the primary voting was held.
Somjet said his committee when introducing the system at the NLA's law vetting meeting did not have give much thought to fraud but on how best to reform politics.
So the law review commitee would go through the point together again and would try to come up with the best conclusion no later than this Tuesday, he said.
The bill is among the first four organic laws necessary for the coming election. It has for the first time introduced the primary voting system, under which party members would be allowed to vote on MP candidates at party branches nationwide.
