As the commission is the executive branch, candidates are chosen individually by the national governments. Within the EU, the legitimacy of the commission is mainly drawn from the vote of approval that is required from the European Parliament, along with its power to dismiss the body. Eurosceptics have therefore raised the concern of the relatively low turnout (often less than 50%) in elections for the European Parliament since 1999. While that figure may be higher than that of some national elections, including the off-year elections of the United States Congress, the fact that there are no direct elections for the position of commission president calls the position's legitimacy into question in the eyes of some Eurosceptics. The fact that the commission can directly decide (albeit with oversight from specially formed 'comitology committees') on the shape and character of implementing legislation further raises concerns about democratic legitimacy.
