Following the constitutional revision of 2001, the conference has been entrusted with the power to select, either unanimously or with the concurrence of 4/5 of its members, the board members of all independent regulatory authorities provided for by the constitution, the president, the vice-president and two members of the Statistics Authority, and the presidents and vice-presidents of the Council of State, the Court of Cassation and the Court of Audit, including the general prosecutor of the Court of Cassation. Scientific Council and Scientific Service of the Parliament The Scientific Council has ten members, nine of whom are university professors, whilst the tenth is a high-ranking public officer. The president of the Scientific Council is mainly responsible for approving and distributing draft laws and law proposals to the appropriate directorate for scientific elaboration, coordinating the cooperation and supervision of the work and studies undertaken by the scientific service, evaluating the work by the research fellows of the scientific service and carrying out seminars for the dissemination of scientific information to MPs. Legislative process Bills, amendments and additions Both the government and MPs may submit bills, amendments and additions to parliament. Government bills are called draft laws () and must always be accompanied by the General Accounting Office's report estimating its effect on the state budget. Bills originating from an MP are called law proposals () and must not include provisions benefiting a particular person or persons, such as increases in salaries or pensions, that would lead to a decrease in government revenue. It is also mandatory that an explanatory report is attached to all bills, elaborating on the purpose of the proposed legislation and indicating the exact wording of current legislation to be amended or repealed. Draft laws (but not law proposals) must also be accompanied by an impact assessment report and by a report on the results of the public consultation that took place prior to the submission of the bill. Finally, all bills are examined by the parliament's own scientific agency, which submits a review on the proposed provisions. Regular legislative procedure In most cases, the bill is first examined and amended by the appropriate committee in two stages taking place at least seven days apart. At the first stage a debate in principle and on the articles is conducted and at the second stage a second reading
