The Korean Constitution vests the following entities with the authority to enact laws: the National Assembly, the President, the Prime Minister, Ministries, the Supreme Court, the Constitutional Court, Administrative Agencies, and the local governments. These bodies are responsible for proposing, enacting, promulgating, implementing, or amending the laws.
Bills may be introduced by members of the National Assembly or by the Executive. To pass a bill, a majority of the members of of the National Assembly must be present, and also a majority of those present must vote for the bill. Each bill passed by the National Assembly must be sent to the Executive, and the President, if he chooses not to object to the bill, must promulgate the bill within fifteen days.
The President can object to a bill that comes before him by returning the bill to the National Assembly with a written explanation of his objection and suggestion for reconsidering the bill. In this case, the bill can still become a law in the original form if the National Assembly passes the bill again after reconsideration with a majority of the members in attendance and two-thirds of those present voting for passage of the bill.
The President has power to both submit bills to the National Assembly and also to issue laws. Pursuant to Chapter IV, Article 75 of the Constitution, the President can issue presidential decrees that describe in more detail the laws passed.
The members of the National Assembly are elected by citizens for four-year terms and the number cannot be less than 200.
