36In accordance with Article 2 of Regulation No 1/58, which corresponds in substance to the fourth paragraph of Article 24 TFEU and Article 41(4) of the Charter, documents sent to the institutions of the European Union by a person subject to the jurisdiction of a Member State may be drafted in any one of the official languages referred to in Article 1 of that regulation selected by the sender, and the institution’s reply must be drafted in that language. As an essential component of respect for the linguistic diversity of the Union, the importance of which is recalled in the fourth subparagraph of Article 3(3) TEU and Article 22 of the Charter, the right for those persons to choose, from among the official languages of the Union, the language to be used in exchanges with the institutions, such as the European Parliament, is fundamental in nature.
