1. The 1970 Budgetary Treaty gave the Parliament the power to adopt the budget together with the Council. These powers were greatly enhanced in 1975 Budgetary Treaty which made the EP the second arm of a joint Budgetary Authority.
2. Requests for supplementary or amending budgets from the European Parliament, the Council, the Court of Justice or the Court of Auditors shall be forwarded by the Commission to the budgetary authority. The Commission may attach a dissenting opinion. These budgets shall be submitted, examined, prepared and finally adopted in the same form and according to the same procedure as the budget whose estimates they are amending. They must be substantiated by reference to the latter. The competent authorities shall discuss them in the light of their urgency. All preliminary draft supplementary budgets must, as a general rule, be forwarded to the Council by the date laid down for the submission of the preliminary draft budget for the following financial year.
