bicameral legislature

Dual-chamber lawmaking body

A bicameral legislature is a lawmaking body divided into two separate chambers or houses, each of which must typically approve legislation before it becomes law.

The United States Congress, with its Senate and House of Representatives, is a prominent example, as is the British Parliament with its House of Lords and House of Commons.

The two-chamber structure often balances different forms of representation—population-based in one house, equal representation of states or regions in the other—and provides a check on hasty lawmaking.
