The first paragraph is based on Article 13 of the ECHR:
‘Everyone whose rights and freedoms as set forth in this Convention are violated shall have an effective remedy before a national authority notwithstanding that the violation has been committed by persons acting in an official capacity.’
However, in Union law the protection is more extensive since it guarantees the right to an effective remedy before a court. The Court of Justice enshrined that right in its judgment of 15 May 1986 as a general principle of Union law (Case 222/84 Johnston  ECR 1651; see also judgment of 15 October 1987, Case 222/86 Heylens  ECR 4097 and judgment of 3 December 1992, Case C-97/91 Borelli  ECR I-6313). According to the Court, that general principle of Union law also applies to the Member States when they are implementing Union law. The inclusion of this precedent in the Charter has not been intended to change the system of judicial review laid down by the Treaties, and particularly the rules relating to admissibility for direct actions before the Court of Justice of the European Union. The European Convention has considered the Union's system of judicial review including the rules on admissibility, and confirmed them while amending them as to certain aspects, as reflected in Articles 251 to 281 of the Treaty on the Functioning of the European Union, and in particular in the fourth paragraph of Article 263. Article 47 applies to the institutions of the Union and of Member States when they are implementing Union law and does so for all rights guaranteed by Union law.
The second paragraph corresponds to Article 6(1) of the ECHR which reads as follows:
‘In the determination of his civil rights and obligations or of any criminal charge against him, everyone is entitled to a fair and public hearing within a reasonable time by an independent and impartial tribunal established by law. Judgment shall be pronounced publicly but the press and public may be excluded from all or part of the trial in the interests of morals, public order or national security in a democratic society, where the interests of juveniles or the protection of the private life of the parties so require, or to the extent strictly necessary in the opinion of the court in special circumstances where publicity would prejudice the interests of justice.’
In Union law, the right to a fair hearing is not confined to disputes relating to civil law rights and obligations. That is one of the consequences of the fact that the Union is a community based on the rule of law as stated by the Court in Case 294/83, ‘Les Verts’ v European Parliament (judgment of 23 April 1986,  ECR 1339). Nevertheless, in all respects other than their scope, the guarantees afforded by the ECHR apply in a similar way to the Union.
With regard to the third paragraph, it should be noted that in accordance with the case-law of the European Court of Human Rights, provision should be made for legal aid where the absence of such aid would make it impossible to ensure an effective remedy (ECHR judgment of 9 October 1979, Airey, Series A, Volume 32, p. 11). There is also a system of legal assistance for cases before the Court of Justice of the European Union.
