The European Commission is the main executive body of the European Union. Article 17(1) of the Treaty on European Union states the Commission should "promote the general interest of the Union" while Article 17(3) adds that Commissioners should be "completely independent" and not "take instructions from any Government". Under article 17(2), "Union legislative acts may only be adopted on the basis of a Commission proposal, except where the Treaties provide otherwise." This means that the Commission has a monopoly on initiating the legislative procedure, although the Council is the "de facto catalyst of many legislative initiatives". The Parliament can also formally request the Commission to submit a legislative proposal but the Commission can reject such a suggestion, giving reasons. The Commission's President (currently an ex-Luxembourg Prime Minister, Jean-Claude Juncker) sets the agenda for the EU's work. Decisions are taken by a simple majority vote, usually through a "written procedure" of circulating the proposals and adopting if there are no objections.[citation needed] Since Ireland refused to consent to changes in the Treaty of Lisbon 2007, there remains one Commissioner for each of the 28 member states, including the President and the High Representative for Foreign and Security Policy (currently Federica Mogherini). The Commissioners (and most importantly, the portfolios they will hold) are bargained over intensively by the member states. The Commissioners, as a block, are then subject to a qualified majority vote of the Council to approve, and majority approval of the Parliament. The proposal to make the Commissioners be drawn from the elected Parliament, was not adopted in the Treaty of Lisbon. This means Commissioners are, through the appointment process, the unelected subordinates of member state governments.
