344_54 substantive_scope 54. As to whether the applicants personally could rely on the provisions of Article 11, the Court reiterates that peaceful participants of a protest tarnished by isolated acts of violence committed by other participants do not cease to enjoy the right to peaceful assembly (see Kudrevičius and Others v. Lithuania [GC], no. 37553/05, § 94, ECHR 2015, and Ziliberberg v. Moldova (dec.), no. 61821/00, 4 May 2004). It does not appear from any submissions that the applicants were among those responsible for the initial acts of aggression which contributed to the deterioration of the protest’s originally peaceful character. As regards the breaking through the police cordon imputed to the applicants, they denied having pushed through the cordon, and even if the applicants found themselves beyond the cordon, there is no evidence that it had been the result of their deliberate effort. According to the material in the case file, the cordon rupture had resulted from the pressure of the crowd which had built up because of the unexpected and unannounced change by the authorities of the venue layout (see also Frumkin, cited above, §§ 113-16 and 132). Apart from that, the applicants’ behaviour remained strictly peaceful, including the chanting of political slogans by the first applicant. The Court therefore considers that the applicants enjoyed the protection of Article 11 in the present case.
