The Margin of Appreciation
If a protest is specifically designed to disrupt activities, the state is afforded a wide margin of appreciation - Barraco v France (2009). However, a peaceful protest on a subject of public interest will see states given a narrow degree of flexibility - Stankov and UMOI v Bulgaria (2001).
Where there is considerable consensus on an issue, such as gay rights, states cannot expect to be given a wide margin of appreciation. In Alekseyev v Russia the court held there to be no pressing social need for the banning of a gay pride march, and so the ban was not necessary in democratic society. In contrast, the interference with freedom of assembly in Cisse v France was proportionate as health conditions had deteriorated, and so the state had a wide margin of appreciation.
Proportionality and the Margin of Appreciation
The Court will consider whether or not the state exercised its discretion reasonably, carefully and in good faith. It must also look at the interference complained of in the light of the case as a whole and determine whether it was “proportionate to the legitimate aim pursued” and whether the reasons adduced by the national authorities to justify it are “relevant and sufficient”.
