The Chamber may vote in three manners. Firstly, it may vote by roll call. In the past, the names of the members were read in alphabetical order and each member had to announce his or her vote when his name was called, however, since 1995, voting by roll call has been done electronically. Voting by roll call is the most frequently used method and is compulsory in three cases: at the end of debates on a government statement, the vote on bills as a whole and when requested by at least eight members. Secondly, the Chamber may vote by sitting and standing. This method is used in less important cases requiring quick treatment and in which there is a clear majority. In the event of doubt, the vote is taken again or done electronically. Voting by sitting and standing is anonymous and is used for votes on amendments and individual articles of a bill. Finally, the Chamber may conduct a secret vote. In principle, the votes are public and votes on legislation are never secret, only the appointments and nominations the Chamber has to make take place by secret vote.
