"The Court recalls that in its above-mentioned Vogt judgment (pp. 25–26, § 52) it articulated as follows the basic principles laid down in its judgments concerning Article 10: (i) Freedom of expression constitutes one of the essential foundations of a democratic society and one of the basic conditions for its progress and 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 that pluralism, tolerance and broadmindedness without which there is no “democratic society”. Freedom of expression, as enshrined in Article 10, is subject to a number of exceptions which, however, must be narrowly interpreted and the necessity for any exceptions must be convincingly established. (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 a European supervision, embracing both the law and the decisions applying it, even those given by independent courts. 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. "
