text: Through Article 17 of the Treaty on European Union the commission has several responsibilities: to develop medium-term strategies; to draft legislation and arbitrate in the legislative process; to represent the EU in trade negotiations; to make rules and regulations, for example in competition policy; to draw up the budget of the European Union; and to scrutinise the implementation of the treaties and legislation. The rules of procedure of the European Commission set out the commission's operation and organisation.
  Executive power
  Before the Treaty of Lisbon came into force, the executive power of the EU was held by the council: it conferred on the Commission such powers for it to exercise. However, the council was allowed to withdraw these powers, exercise them directly, or impose conditions on their use. This aspect has been changed by the Treaty of Lisbon, after which the Commission exercises its powers just by virtue of the treaties. Powers are more restricted than most national executives, in part due to the commission's lack of power over areas like foreign policy – that power is held by the Council of the European Union and the European Council, which some analysts have described as another executive.
  Considering that under the Treaty of Lisbon, the European Council has become a formal institution with the power of appointing the commission, it could be said that the two bodies hold the executive power of the EU (the European Council also holds individual national executive powers). However, it is the Commission that currently holds most of the executive power over the European Union.
