Legislatures are institutions of government that are directly elected to represent local districts and citizens. A legislature has several key functions: representing citizens, deliberating on public matters, legislating or passing bills into law, authorizing government expenditures, forming governments, and overseeing the executive. Legislatures have either one or two chambers and operate through committees where most lawmaking is done. Effective legislatures have appropriate powers, committed members, and resources to represent citizens, pass effective laws, and provide oversight of the government.
