28 DELFI AS v. ESTONIA JUDGMENT (d) Necessary in a democratic society (i) General principles 78. The fundamental principles concerning the question whether an interference with freedom of expression is “necessary in a democratic society” are well established in the Court’s case-law and have been summarised as follows (see, among other authorities, Hertel v. Switzerland, 25 August 1998, § 46, Reports of Judgments and Decisions 1998-VI; Steel and Morris v. the United Kingdom, no. 68416/01, § 87, ECHR 2005-II; Mouvement raëlien suisse v. Switzerland [GC], no. 16354/06, § 48, ECHR 2012 (extracts)); and Animal Defenders International v. the United Kingdom [GC], no. 48876/08, § 100, 22 April 2013: “(i) Freedom of expression constitutes one of the essential foundations of a democratic society and one of the basic conditions for its progress and for each individual’s self-fulfilment. Subject to paragraph 2 of Article 10, it is applicable not only to ‘information’ or ‘ideas’ that are favourably received or regarded as inoffensive or as a matter of indifference, but also to those that offend, shock or disturb. Such are the demands of pluralism, tolerance and broadmindedness without which there is no ‘democratic society’. As set forth in Article 10, this freedom is subject to exceptions, which ... must, however, be construed strictly, and the need for any restrictions must be established convincingly ... (ii) The adjective ‘necessary’, within the meaning of Article 10 § 2, implies the existence of a ‘pressing social need’. The Contracting States have a certain margin of appreciation in assessing whether such a need exists, but it goes hand in hand with European supervision, embracing both the legislation and the decisions applying it, even those given by an independent court. The Court is therefore empowered to give the final ruling on whether a ‘restriction’ is reconcilable with freedom of expression as protected by Article 10. (iii) The Court’s task, in exercising its supervisory jurisdiction, is not to take the place of the competent national authorities but rather to review under Article 10 the decisions they delivered pursuant to their power of appreciation. This does not mean that the supervision is limited to ascertaining whether the respondent State exercised its discretion reasonably, carefully and in good faith; what the Court has to do is to look at the interference complained of in the light of the case as a whole and determine whether it was ‘proportionate to the legitimate aim pursued’ and whether the reasons adduced by the national authorities to justify it are ‘relevant and sufficient’.... In doing so, the Court has to satisfy itself that the national authorities applied standards which were in conformity with the principles embodied in Article 10 and, moreover, that they relied on an acceptable assessment of the relevant facts ....” 79. Furthermore, the Court reiterates the essential function the press fulfils in a democratic society. Although the press must not overstep certain bounds, particularly as regards the reputation and rights of others and the need to prevent the disclosure of confidential information, its duty is nevertheless to impart – in a manner consistent with its obligations and responsibilities – information and ideas on all matters of public interest (see
