In the 2014-2019 legislature, one of the 464 laws adopted was initiated by citizens.

Organic law may only be introduced by the Council of Ministers upon the recommendation of the Supreme Court, the Constitutional Court or a relevant Independent Organ, and members of the House of Representatives comprising not less than one-tenth of the total number of existing members (Constitution of the Kingdom of Thailand , B.E. 2560 (2017), Section 131).

Executive-legislative relations

Legislation adopted by parliament requires the assent of the Head of State
No

Notes: A bill does not require the King's assent to become law because the National Assembly has the final authority. If the King refuses to sign or does not act within 90 days, the bill returns to the National Assembly for reconsideration. If at least two-thirds of both Houses reaffirm the bill, it is resent to the King. If he still does not sign within 30 days, the Prime Minister must publish it in the Government Gazette, making it law without the King's signature.
