or rules of order
Generally accepted rules, precedents, and practices used in the governance of deliberative assemblies.
They are intended to maintain decorum, ascertain the will of the majority, preserve the rights of the minority, and facilitate the orderly transaction of business. Rules of parliamentary procedure originated in Britain in the 16th and 17th centuries and were subsequently adopted by legislatures around the world. Robert's Rules of Order , codified in 1876 by U.S. Gen. Henry M. Robert (1837–1923) and regularly refined and enlarged, is the standard set of rules used by legislatures in the U.S.
