A unicameral legislature is a type of legislative body that consists of a single chamber or house. This means that all lawmakers meet in one assembly to discuss and pass laws, rather than being divided into two separate chambers, as seen in a bicameral legislature. Countries or regions with a unicameral system often aim for more efficient decision-making and streamlined processes. Many states in the United States, such as Nebraska, operate under a unicameral system. This structure can simplify the legislative process, as there is no need for coordination between two houses. However, critics argue that it may limit representation and debate on important issues.
