The primary function of the legislative branch in a government is to create, amend, and repeal laws. This branch is responsible for representing the electorate's interests and ensuring that public policies align with societal needs. Legislatures carry out this function through proposing bills, holding debates, and voting on legislation. Furthermore, the legislative branch exercises oversight over the executive branch to ensure accountability and transparency. By reflecting the will of the people, the legislative branch plays a crucial role in shaping governance and maintaining the foundational principles of democracy.
