120_76 interference 76. The Court further notes that the demonstration in question is the same demonstration in which the applicant in the above-mentioned case of Galstyan participated. In that case, the Court established that the demonstration in question was neither intended to be not peaceful nor was it prohibited. Furthermore, the authorities never attempted to disperse the demonstration or to order its participants, including the applicant, to leave on account of it being illegal or unauthorised or obstructing traffic (ibid., § 101). It is true that, in the present case, the police report stated that the applicant had participated in an unauthorised march heading from the Research Institute towards the Constitutional Court (see paragraph 10 above). However, first of all, this allegation was not confirmed in the course of the court proceedings since the applicant was not convicted for her participation in an allegedly unauthorised march, but for certain actions committed at the demonstration on the Mashtots Avenue located in front of the Research Institute (see paragraph 17 above). Secondly, it is not clear on what grounds such an allegation was made by the reporting police officer taking into account that at the material time there was no legal act applicable in Armenia containing rules for organising and holding rallies and street marches, including the rules for authorising such events (see Mkrtchyan v. Armenia, no. 6562/03, § 43, 11 January 2007). The Court further notes that the Government did not allege that the demonstration was unauthorised or unlawful either. There is therefore nothing in the materials of the present case that would prompt the Court to depart from the findings made in the case of Galstyan. Thus, by joining the demonstration, the applicant availed herself of her right to freedom of peaceful assembly and the sanction that followed amounted to an interference with that right.
