The draft legislation would cancel the immunity granted to the 2006 coup-makers under Article 309 of the Constitution.
Weng said he intended the repeal of the immunity provision to serve as a bold gesture opposing the seizure of political power.
Opposition lawmakers are opposed to cancelling the immunity, begging the question as to whether they condone coups, he said.
He said he strongly believed that no politicians of any stripe are in favour of seizing power.
“Amending Article 309 would send a strong message rejecting power seizures,” he said.
The ruling party is expected to debate the draft next week before deciding whether to push for parliamentary deliberation.
