598_54 interference 54. Turning to the circumstances of the present case, the Court considers that the interference at issue resulted from the applicant’s arrest at a demonstration and his subsequent conviction of administrative offences leading to a sanction of eight days’ detention. The interference in question was “prescribed by law” as it was based on Article 173 of the CAO (see paragraph 28 above). The Court further accepts that, in the circumstances of the present case, the interference pursued the legitimate aim of preventing disorder and protecting the rights of others. Therefore, the Court’s task is to determine whether the interference with the applicant’s right to freedom of assembly, considered in the light of the right to freedom of expression, answered a “pressing social need” and was “proportionate to the legitimate aim pursued.”
