The European Parliament is the first of the Union institutions listed in Article 13(1) TEU. As an ‘institution’, it enjoys a certain number of rights, prerogatives, and privileges, and is subject to a certain number of obligations. Thus, for example, in its decision-making, Parliament must ‘promote the Union’s values, advance its objectives, serve its interests and those of its citizens and … Member States’; it must also ‘ensure constant respect for the principles of subsidiarity and proportionality’, ‘act within the limits of the powers conferred on it in the Treaties’, and comply with any international agreements concluded by the Union. It must maintain a dialogue with civil society, conduct its work as openly as possible, grant citizens a right of access to documents it holds, and protect the personal data of individuals in its procession. Parliament may participate as of right in most types of proceedings before the Court of Justice of the European Union (CJEU) and enjoys legal capacity in the Member States in respect of matters concerning its own functioning. It is also subject to the auditing authority of the Court of Auditors and the jurisdiction of the European Ombudsman as regards allegations or investigations of maladministration. More
