70Those conditions correspond, in essence, to those laid down by the case-law of the European Court of Human Rights (‘the ECtHR’), according to which, in order to be justified under Article 10(2) of the ECHR, an interference with the right to freedom of expression must have been ‘prescribed by law’, intended for one or more of the legitimate aims set out in that paragraph, and ‘necessary in a democratic society’ to achieve that aim or aims (ECtHR, 15 October 2015, Perinçek v. Switzerland, CE:ECHR:2015:1015JUD002751008, paragraph 124). It follows that the criterion at issue must be interpreted as meaning that the Council was allowed to adopt restrictive measures liable to limit the applicant’s freedom of expression, provided that those limitations comply with the conditions set out above, all of which must be satisfied in order for that freedom to be legitimately restricted.
