51In order to ensure, in practice, that those conditions are fully observed, it is essential that access of the competent national authorities to retained data be subject to a prior review carried out either by a court or by an independent administrative body, and that the decision of that court or body be made following a reasoned request by those authorities submitted, inter alia, within the framework of procedures for the prevention, detection or prosecution of crime. In cases of duly justified urgency, the review must take place within a short time (see, to that effect, judgment of 6 October 2020, La Quadrature du Net and Others, C‑511/18, C‑512/18 and C‑520/18, EU:C:2020:791, paragraph 189 and the case-law cited).
