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:
“Yesterday the Electoral Commission decided not to go behind the papers filed with the Vice-President in the case of Florida.... I read the arguments in the Congressional Record and can’t see how lawyers can differ on the question. But the decision is by a strictly party vote—eight Republicans against seven Democrats! It shows the strength of party ties.”
—Rutherford Birchard Hayes (1822–1893)
“If surrealism ever comes to adopt a particular line of moral conduct, it has only to accept the discipline that Picasso has accepted and will continue to accept.”
—André Breton (1896–1966)
