Can an EDPS decision against Europol help me in national court proceedings?

An EDPS finding that Europol processed your data unlawfully creates persuasive — sometimes binding — authority in national proceedings. Courts in EU Member States must consider whether evidence derived from unlawfully processed Europol data should be excluded or given reduced weight. In extradition and mutual legal assistance cases, an EDPS decision documenting data protection violations can support arguments that cooperation should be refused on human rights grounds. The decision also establishes an official record that can be cited in civil claims for damages under EU law.
