It is the role of the Committee of Ministers to supervise the execution of court judgements, though they have no formal means of forcing member countries to comply. However, the ultimate sanction of non-compliance is expulsion from the Council of Europe and thus becoming a 'pariah' state within Europe. Furthermore, the European Union takes a keen interest in the Convention and Court (and its jurisprudence) so would not look kindly upon any EU member state that did not fulfill its Convention obligations.
