Amendments to the Rules of Procedure of the Court of Justice [2026/1335]

Official Journal EN of the European Union L series 2026/1335 17.6.2026 AMENDMENTS TO THE RULES OF PROCEDURE OF THE COURT OF JUSTICE[2026/1335] THE COURT OF JUSTICE, Having regard to the Treaty on the Functioning of the European Union, and in particular the sixth paragraph of Article 253 thereof, Having regard to the Treaty establishing the European Atomic Energy Community, and in particular Article 106a(1) thereof, Having regard to the Protocol on the Statute of the Court of Justice of the European Union, and in particular Article 63 thereof,

Whereas, in view of questions raised concerning the situations in which Member States are entitled to use their official language in procedures before the Court, it is necessary to clarify the scope of the derogation provided for in Article 38(4) of the Rules of Procedure and to specify that the possibility, for Member States, of using their official language applies to all cases in which they take part and to all requests, applications or actions brought before the Court, including appeals brought under Articles 56 or 57 of the Protocol on the Statute of the Court of Justice of the European Union,

Whereas, moreover, certain procedural requirements laid down in the Rules of Procedure should be streamlined or removed, either because they have become redundant as a result of recent technological developments or because of the workload they entail and their impact on the length of proceedings,

Whereas, to that end, the obligation to draw up minutes should be limited to hearings of oral argument, and a distinction should be drawn between the procedural requirements for the reopening of the oral part of the procedure and the less onerous procedural requirements applicable to the opening of the oral part,

Whereas it is also appropriate to draw on the Court’s case-law on confidentiality and to relieve the Court of the obligation to make an order where, in the context of an appeal, the same confidential treatment as that approved by the General Court at first instance is sought by a party to the proceedings vis-à-vis another party,

Whereas account should also be taken of the experience gained by the Court following the death of a Judge or the simultaneous departure of several Judges, and provision should be made for the President of the formation of the Court to certify that a Judge who is no longer in a position to sign the original of the judgment or of the Opinion of the Court did take part in the deliberations of that formation,

Whereas, finally, it is appropriate to facilitate the management of cases which are subject to the mechanism whereby the Court determines whether an appeal should be allowed to proceed and to ensure a more balanced distribution of the workload between all the Judges by changing the date to be taken into account for the purpose of establishing the composition of the Chamber determining whether appeals may proceed, this being established by reference to the date on which a Judge is designated as Judge-Rapporteur, and not by reference to the date on which the request that the appeal be allowed to proceed is made, With the approval of the Council given on 11 May 2026,
