This article examines the application of the right of access to a court as guaranteed by Article 47 of the EU Charter of Fundamental Rights in cases involving State immunity. First, it considers the scope of the right of access to a court under the Charter, including its relationship with Article 6(1) of the European Convention on Human Rights, and the ways in which the Charter is given effect within UK law. Second, the article critically examines the Court of Appeal’s application of both Article 6(1) ECHR and Article 47 of the EU Charter in Benkharbouche v Sudan, a case brought by domestic service staff of foreign embassies based in London against Sudan and Libya respectively. It argues that the Court’s statement that the right of access to a court is not engaged in immunity cases because the court has no jurisdiction to exercise – an analysis which relies on Lord Millett’s reasoning in Holland v Lampen-Wolfe and the dicta of Lords Bingham and Hoffmann in Jones v Saudi Arabia – is erroneousness: the right of access to a court is always engaged in immunity cases because immunity does not deprive the courts of jurisdiction ab initio. The article also argues that contrary to the Court’s reasoning on Article 47 of the EU Charter, the right of access to a court does not need to have horizontal effect in a private between private parties: the right is always enforced against the forum State; it has indirect, not horizontal, effect.
