to fall if an absolute majority of the legislators votes for a motion of no confidence. As a result, the government usually consists of members from the political party that dominates the Assembly and must be supported by a majority there to prevent a vote of no-confidence. The Prime Minister and other government Ministers are appointed by the President, who is under no constitutional or other mandatory obligation to make governmental appointments from the ranks of the majority party in parliament. This is a safeguard that was introduced by the founder of the Fifth Republic, Charles de Gaulle, to attempt to prevent the disarray and horse-trading seen in the parliamentary regimes of the Third and Fourth Republics; however, in practice the prime minister and other ministers usually do belong to the majority party. A notable exception to this custom occurred during Nicolas Sarkozy's premiership when he appointed socialist ministers and Secretary of State-level junior ministers to his government. The rare periods during which the president is not from the same political party as the prime minister are usually known as cohabitation. The Cabinet of Ministers is led by the President rather than the Prime Minister. The government (or, when it sits in session every Wednesday, the cabinet) exerts considerable influence on the agenda of Parliament. The government can link its term to a legislative text which it proposes, and unless a motion of censure is introduced within 24 hours of the proposal and passed within 48 hours of introduction – thus full procedures last at most 72 hours – the text is considered adopted without a vote. However, this procedure was limited by a 2008 constitutional amendment. Legislative initiative rests with the National Assembly. Legislators enjoy parliamentary immunity. Both assemblies have committees that write reports on a variety of topics. If necessary, they can establish parliamentary commissions of inquiry with broad investigative power. However, this is almost never exercised because the majority can reject a proposition by the opposition to create an investigatory commission. Also, such a commission may only be created if it does not interfere with a judicial investigation, meaning that in order to cancel its creation, one just needs to press charges on the topic concerned by the investigatory commission. Since 2008, the opposition may impose the creation of an investigative commission once a year, even against the wishes of the majority. However, they still cannot lead
