In October 2010, Oleksiy Vyerentsov was arrested and sentenced to three days administrative detention. His crime: organising a peaceful demonstration in protest against corruption in the Ukrainian prosecution service. Left with inadequate time to prepare his defence, and deprived of the opportunity to consult with a lawyer, Oleksiy decided to lodge a complaint with the European Court of Human Rights.

In its judgment, the Court found several violations of the European Convention including the right to peaceful assembly and the right to a fair trial.
