Parliamentary Law Law and Legal Definition

Parliamentary law is the body of law which governs the conduct of the meeting of a legislative body. It is the rules and usages of parliament, or of deliberative bodies. A rule of parliamentary law is a rule created and adopted by the legislative or deliberative body it is intended to govern. Such rules are quite different from constitutional provisions which the people have set up as defining and limiting the powers and duties of the legislature. The former are subject to revocation and modification at the pleasure of the body creating them, while the latter are the law of its being, and prescribe the terms upon which it has power to act at all.
