The Supreme Court ruled on the legal consequences of the judgment of the Court of Justice of the European Union in Case C-502/19 concerning Mr Oriol Junqueras – the supporter of the independence of Catalonia convicted of sedition and misappropriation of public funds. Mr O. Junqueras was elected Member of the European Parliament while he was in provisional detention, but after the trial stage of the criminal proceedings brought against him had been opened. The CJEU judgment concerned the scope of the immunity enjoyed by MEPs. The Supreme Court ruled, in accordance with the CJEU interpretation, that Mr Junqueras enjoyed the immunity. However, the prison sentence passed on him deprived him of his MEP status and therefore a request to waive the immunity in this particular case was not applicable.
