(6)The Court of Justice of the European Union has recognised delegation of authority to be necessary and appropriate to enable an institution required to adopt a considerable number of decisions to perform its duties. The powers conferred on an institution include the right to delegate, in compliance with the provisions of the TFEU, a certain number of those powers, subject to any conditions specified by the institution. A Union institution may therefore establish measures of an organisational nature, delegating its decision-making powers to its own internal bodies or persons, insofar as such measures are justified and respect the principle of proportionality. In order to ensure legal certainty, the delegation of decision-making powers should be both limited and proportionate, and the scope of the delegation should be clearly defined and subject to conditions specified by the institution.
