GREVIO is the independent expert body responsible for monitoring the implementation of the Council of Europe Convention on Preventing and Combating Violence against
Women and Domestic Violence (Istanbul Convention) by the parties, made up of 15 independent experts. It draws up and publishes reports evaluating legislative and other measures taken by the parties to give effect to the provisions of the convention. In cases where action is required to prevent a serious, massive or persistent pattern of any acts of violence covered by the convention, GREVIO may initiate a special inquiry procedure. GREVIO may also adopt, where appropriate, general recommendations on themes and concepts of the convention.
