A democratic deficit (or democracy deficit) occurs when ostensibly democratic organizations or institutions (particularly governments) fall short of fulfilling the principles of democracy in their practices or operation where representative and linked parliamentary integrity becomes widely discussed.
The phrase democratic deficit is cited as first being used by the Young European Federalists in their Manifesto in 1977, which was drafted by Richard Corbett. The phrase was also used by David Marquand in 1979, referring to the then European Economic Community, the forerunner of the European Union.
The UN Parliamentary Assembly has been proposed as a way of ameliorating a democractic deficit within the United Nations.
Some scholars have argued that the ratification of European Union treaties by repeated referendums—such as those held in Ireland for the Treaty of Nice and the Treaty of Lisbon—is also associated with a democratic deficit.
