The subject of the study is to analyze EU citizens’ right to court in the light of the procedural regulations of the court of Justice and the General Court included in the CJEU Statute and court regulations. The study analyzes also, to a necessary extent, the body of previous judicial decisions of CJEU as well as the provisions of relevant acts of derivative law concerning the issues in question. Considering the complexity of the analyzed subject and the limitations of the size of the present study, the focus was put on questions related to legal aid and rules of representation. Upon through analysis, the study confirms that in proceedings before EU courts EU citizens have limited possibilities in the scope of the capacity to act in legal proceedings, which constitutes one of the most basic factors limiting their right to court.
