Request for advisory opinion rejected


The Court has decided on 14 December 2020 to reject the request for an advisory opinion submitted by the Slovak Supreme Court concerning the independence of the current mechanism for assessing complaints against the police.

The ECHR considered that the points raised did not concern an issue for which the Slovak Supreme Court required guidance so that it could ensure respect for Convention rights in hearing and determining the case in question.
