Party discipline is the ability of a parliamentary group of a political party to get its members to support the policies of their party leadership. In liberal democracies, it usually refers to the control that party leaders have over its legislature. Party discipline is important for all systems of government that allow parties to hold political power because it determines the degree to which the governmental infrastructure will be affected by legitimate political processes.
The term has a somewhat different meaning in Marxist-Leninist political systems such as the People's Republic of China. In this case it refers to administrative sanctions such as fines or expulsion that the Communist Party can impose on its members for actions such as corruption or disagreeing with the party.
Breaking party discipline in actual parliamentary votes is called crossing the floor.
Famous quotes containing the words party and/or discipline:
“[John] Brough’s majority is “glorious to behold.” It is worth a big victory in the field. It is decisive as to the disposition of the people to prosecute the war to the end. My regiment and brigade were both unanimous for Brough [the Union party candidate for governor of Ohio].”
—Rutherford Birchard Hayes (1822–1893)
“The first rule of education for me was discipline. Discipline is the keynote to learning. Discipline has been the great factor in my life. I discipline myself to do everything—getting up in the morning, walking, dancing, exercise. If you won’t have discipline, you won’t have a nation. We can’t have permissiveness. When someone comes in and says, “Oh, your room is so quiet,” I know I’ve been successful.”
—Rose Hoffman, U.S. public school third-grade teacher. As quoted in Working, book 8, by Studs Terkel (1973)
