An Act respecting the exercise of the fundamental rights and prerogatives of the Québec people and the Québec State (R.S.Q., c. E-20.2) (French: Loi sur l'Exercice des droits fondamentaux et des prérogatives du peuple québécois et de l'État du Québec, L.R.Q. c. E-20.2) is a Quebec law passed in opposition and in contradiction with the federal Clarity Act (S.C. 2000, c. 26). The Act was introduced by Joseph Facal to the National Assembly of Quebec in emergency on 15 December 1999, two days after the introduction of Bill C-20 before the Canadian House of Commons. It was adopted on 7 December 2000, by a majority of 69 against 41.

Whereas the federal act states that, in the case of a referendum about the secession of a Canadian province, the House of Commons has the power to determine afterwards whether the question was clear enough and whether the obtained majority was large enough for the result to be accepted, the provincial one stipulates that Quebecers could opt for the secession of Quebec State in a 50% + 1 referendum. The act is merely a political statement and has no effect in law.
