Legislature

A legislature is the law-making body of a political unit, usually a national government, that has power to amend and repeal public policy. Laws enacted by legislatures are known as legislation. Legislatures observe and steer governing actions and usually have exclusive authority to amend the budget or budgets involved in the process. The most common names for national legislatures are "parliament" and "congress". The members of a legislature are called legislators.

Terminology

Because members of legislatures usually sit together in a specific room to deliberate, seats in that room may be assigned exclusively to members of the legislature. In parliamentary language, the term "seat" is sometimes used to mean that someone is a member of a legislature. For example, to say that a legislature has 100 "seats" means that there are 100 members of the legislature; and saying that someone is "contesting a seat" means they are trying to be elected as a member of the legislature. By extension, the term "seat" is often used in less formal contexts to refer to an electoral district itself, as, for example, in the phrases "safe seat" and "marginal seat".
