Majority and Minority

              A party or parliamentary group composed by the absolute majority (half of the members plus one) of representatives is called Majority in Brazil. Since the Chamber has 513 members, the Majority must have 257 representatives. Due to the proportional electoral system, it is very difficult to have a one-party absolute majority at the Chamber, though it can be achieved with a Parliamentary group formed by a coalition of several political parties. The Chamber Rules and Manual states that if there is no absolute majority in a party or in a party group the Majority will be the party or Party group with a simple plurality, i.e. having more representatives than any other.
              The bigger party or party group opposing to the Majority’s thought about the Chief of the Executive Branch’s Party (The Government)  is called the Minority in Brazil.  Therefore if the Majority is pro Government, the Minority will be the biggest party or the biggest party group against the Executive’s ideas.
