 Whether a given bill will be proposed is generally a matter of the legislative priorities of government.Legislation is regarded as one of the three main functions of government, which are often distinguished under the doctrine of the separation of powers.Those who have the formal power to "create" legislation are known as legislators; a judicial branch of government will have the formal power to "interpret" legislation (see statutory interpretation); the executive branch of government can act only within the powers and limits set by the law, which is the instrument by which the fundamental powers of government are established.
