The principle of Community institutional balance implies that each institution has to act in accordance with the powers conferred on it by the Treaties. The principle itself is not set out in so many words in the Treaties but derives from a judgment by the Court of Justice of the European Communities by prohibiting any encroachment by one institution on the powers conferred on another. It is the Court's responsibility to ensure that this principle is respected. Democratic legitimacy implies that the majority of population accepts the jurisdiction of the authority.
