When assessing a change of circumstances in a third country, the competent authorities of the Member States should verify, having regard to the individual situation of a beneficiary of international protection, that the actor or actors of protection in that country have taken reasonable steps to prevent the persecution or serious harm, that they therefore operate, inter alia, an effective legal system for the detection, prosecution and punishment of acts constituting persecution or serious harm and that the beneficiary of international protection will have access to such protection if the refugee status or the subsidiary protection status is withdrawn.
