Parliament's powers have gradually grown with the entry into force of the Single European Act (1986), the Maastricht Treaty (1993) and the Treaty of Amsterdam (1999). Parliament shares decision-making power on an equal footing with the Council in many areas under the Community Pillar to which the "co-decision procedure" applies. The European Parliament is one of the two branches with budgetary authority – the Council is the other. The signature of the EP president brings the overall EU budget into effect. | Parliament's powers have gradually grown with the entry into force of the Single European Act (1986), the Maastricht Treaty (1993) and the Treaty of Amsterdam (1999).
