Judgment_paragraph 51 · GM v Országos Idegenrendészeti Főigazgatóság and Others (C-159/21)

51That weighing up cannot, however, lead, in the light of the necessary observance of Article 47 of the Charter, to depriving the rights of defence of the person concerned of all effectiveness and to rendering meaningless the right to a remedy provided for in Article 45(3) of Directive 2013/32, in particular by not informing that person, or, as the case may be, his or her adviser, at the very least of the substance of the grounds on which the decision taken against him or her is based (see, to that effect, judgment of 4 June 2013, ZZ, C‑300/11, EU:C:2013:363, paragraph 65).
