In Malaysia, a state legislative assembly, officially Dewan Undangan Negeri (DUN), is the legislative branch of the state governments in each of the 13 Malaysian states. Members of a state legislative assembly comprises elected representatives from single-member constituencies during state elections through the first-past-the-post voting system.
The assemblies have powers to enact state laws as provided for by the Constitution of Malaysia. The majority party in each assembly forms the state government, and the leader of the majority party becomes Menteri Besar (for states with hereditary rulers) or Chief Minister (for states without hereditary rulers) of the state.
