Prime Minister Prayut Chan-o-cha has insisted that the national strategy bill does not breach the constitution and has been given a good public airing.
Gen Prayut was speaking after Pheu Thai Party lawyer Ruangkrai Leekitwattana petitioned the Office of the Ombudsman on Monday to look into whether the national strategy bill, and a bill on plans and procedures for national reform, violate the charter.
He also asked for the matter to be forwarded to the Constitutional Court for consideration.
The two bills were passed by the National Legislative Assembly on June 22. They will come into effect when they are published in the Royal Gazette.
Mr Ruangkrai argued that the cabinet resolved to submit the two bills to the NLA on April 4, two days before the new charter came into effect.
In making the decision on April 4, it was wrong for the cabinet to cite the constitution because the charter had not yet been enacted, Mr Ruangkrai added.
Without the charter, the cabinet had no authority to cite the charter to propose the law to the NLA, which could be deemed unconstitutional, he said.
Responding, Gen Prayut insisted that the two bills did not breach the constitution, saying he had consulted with his legal advisers.
The National Reform Steering Assembly, which initiated the bills, held forums to gather feedback on the two bills.
When the bills reached the NLA, the assembly also gathered opinions via websites and other media, the prime minister said.
"There are politicians who keep talking and causing problems. Is it because they resist change? Just stop politicising things and let them finish their job first," Gen Prayut said.
Distat Hotrakitya, secretary-general of the Office of the Council of State, said Tuesday that when the two bills reached the Council of State, it also invited those involved in drafting the bills to give their opinions.
In light of this, the two bills have been given a broad airing, Mr Distat said.
He added that the charter does not specify the format for gathering opinions on legislation, but only requires that opinions be sought from concerned parties.
Under Section 77 of the charter, gathering feedback on legislative bills does not mean holding public forums, but listening to all those involved, he said.
Touted as a crucial piece of legislation to lay the foundations for national development over the next 20 years, the national strategy bill sets out plans for ways to develop Thailand, while any proposals must be in compliance with the national strategy.
The new law will establish a national strategy commission as a de facto "superboard" with the prime minister at the helm to implement the strategy, with various committees set up to design specific action plans.
The three vice-chairmen will be the Senate and House speakers and a deputy prime minister, or a minister assigned by the premier.
The commissioners will be the defence permanent secretary; the supreme commander, chiefs of the army, navy, air force and police; the secretary-general of the National Security Council; chairmen of the National Economic and Social Development Board, the National Farmers Council, the Thai Chamber of Commerce, the Federation of Thai Industries, the Tourism Council of Thailand and the Thai Bankers' Association.
