A "unicameral" legislature is a type of government body that consists of a single chamber or house. This means that all legislative decisions are made within one assembly, as opposed to a bicameral system, which has two separate chambers. Unicameral systems can simplify the legislative process and reduce the time needed to pass laws. Countries like Nebraska in the United States and New Zealand have adopted unicameral legislatures. Supporters argue that this system promotes efficiency and accountability, while critics may contend that it lacks the checks and balances provided by a second chamber.
