The right to freedom of assembly, one of the foundations of a democratic society, is subject to a number of exceptions which must be narrowly interpreted and the necessity for any restrictions must be convincingly established. In examining whether restrictions to the rights and freedoms guaranteed by the Convention can be considered “necessary in a democratic society” the Court has, however, consistently held that the Contracting States enjoy a certain but not unlimited margin of appreciation (see Barraco v. France, no. 31684/05, § 42, 5 March 2009). It is, in any event, for the Court to give a final ruling on the restriction’s compatibility with the Convention and this is to be done by assessing the circumstances of a particular case (see Osmani and Others v. the former Yugoslav Republic of Macedonia (dec.), no. 50841/99, ECHR 2001-X, and Galstyan v. Armenia, no. 26986/03, § 114, 15 November 2007).
