The main functions of a national legislature include creating, amending, and repealing laws, representing the electorate, and overseeing the executive branch. Legislatures are responsible for drafting legislation that addresses public needs and issues within society, often reflecting constituents' interests. Additionally, they play a vital role in the budgetary process, approving funding for various government initiatives. The legislature serves as a check on the executive by holding hearings, conducting investigations, and ensuring accountability. These functions are essential for maintaining democratic governance and fostering public trust in political institutions.
