43As regards the principle of effectiveness in particular, it should be noted that the objective of national rules on the admissibility and use of information and evidence is, in accordance with the choices made by national law, to prevent information and evidence obtained unlawfully from unduly prejudicing a person who is suspected of having committed criminal offences. That objective may be achieved under national law not only by prohibiting the use of such information and evidence, but also by means of national rules and practices governing the assessment and weighting of such material, or by factoring in whether that material is unlawful when determining the sentence (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 225).
