Legislation and primary sources

Where to find the authoritative text of the law in South Korea, and how to confirm it is still in force.

Sources of law, ranked

The Constitution
Supreme; enforced by a dedicated Constitutional Court.
Statutes of the National Assembly
The primary source of private and criminal law.
Presidential decrees and ministerial ordinances
Subordinate legislation, reviewable by the Supreme Court for legality.
Treaties
Article 6 gives duly ratified treaties the same effect as domestic law without further enactment.
Supreme Court precedent
Not formally binding, but departure is rare and a conflicting judgment is a ground of appeal.

The legislative process

Bills may be introduced by the government or by ten or more members of the Assembly. They go to a standing committee, then to the Legislation and Judiciary Committee for legal scrutiny, then to plenary. The President may veto a bill within fifteen days, and the Assembly may override with two-thirds of members present and a majority of those on the roll. A 2012 amendment to the National Assembly Act — the so-called Assembly Advancement Act — requires a three-fifths supermajority to bring most contested bills to a vote, which materially raises the threshold for legislating.
