The right to a fair trial is a fundamental principle of EU law, laid down in Article 47 of the Charter of Fundamental Rights of the European Union.
In order to satisfy the requirements of that law, the European Union judicature must ensure that the principle that the parties should be heard is respected in proceedings before them and that they themselves respect that principle, which applies to any procedure which may result in a decision by an institution of the European Union perceptibly affecting a person’s interests.
