Which majority is needed

Most votes are decided by simple majority: the option with more votes wins, and abstentions do not count. Some decisions need larger majorities, counted over the 230 deputies in office or over the deputies present.

An organic law, such as the electoral law or the nationality law, needs an absolute majority of deputies in office in the final vote. A constitutional revision needs two thirds of deputies in office.

How a law is made

An initiative enters Parliament, is debated and voted in general, examined article by article in a committee and voted again in the final global vote. It then goes to the President and, if signed, is published in the official journal (Diário da República).

The Parlamento section (in Portuguese) shows each initiative, its status and the votes of each party.
