Judgment_paragraph 48 · X v International Protection Appeals Tribunal and Others (C-756/21)

48Although under Article 4(1) of Directive 2004/83 it is the duty of the applicant to submit as soon as possible all elements needed to substantiate the application for international protection, the Court has clarified that the authorities of the Member States must, if necessary, cooperate actively with him or her in order to determine and supplement the relevant elements of the application, those authorities indeed often being better placed than an applicant to gain access to certain types of documents (judgment of 22 November 2012, M., C‑277/11, EU:C:2012:744, paragraphs 65 and 66).
