E/CN.4/Sub.2/2005/17 page 14 19.3 States should ensure that all national policies related to the right to housing, land and property restitution fully guarantee the rights of women and girls to be protected from discrimination and to equality in both law and practice. 20. Enforcement of restitution decisions and judgements 20.1 States should designate specific public agencies to be entrusted with enforcing housing, land and property restitution decisions and judgements. 20.2 States should ensure, through law and other appropriate means, that local and national authorities are legally obligated to respect, implement and enforce decisions and judgements made by relevant bodies regarding housing, land and property restitution. 20.3 States should adopt specific measures to prevent the public obstruction of enforcement of housing, land and property restitution decisions and judgements. Threats or attacks against officials and agencies carrying out restitution programmes should be fully investigated and prosecuted. 20.4 States should adopt specific measures to prevent the destruction or looting of contested or abandoned housing, land and property. In order to minimize destruction and looting, States should develop procedures to inventory the contents of claimed housing, land and property within the context of housing, land and property restitution programmes. 20.5 States should implement public information campaigns aimed at informing secondary occupants and other relevant parties of their rights and of the legal consequences of non-compliance with housing, land and property restitution decisions and judgements, including failing to vacate occupied housing, land and property voluntarily and damaging and/or looting of occupied housing, land and property. 21. Compensation 21.1 All refugees and displaced persons have the right to full and effective compensation as an integral component of the restitution process. Compensation may be monetary or in kind. States shall, in order to comply with the principle of restorative justice, ensure that the remedy of compensation is only used when the remedy of restitution is not factually possible, or when the injured party knowingly and voluntarily accepts compensation in lieu of restitution, or when the terms of a negotiated peace settlement provide for a combination of restitution and compensation. 21.2 States should ensure, as a rule, that restitution is only deemed factually impossible in exceptional circumstances, namely when housing, land and/or property is destroyed or when it no longer exists, as determined by an independent, impartial tribunal. Even under such circumstances the holder of the housing, land and/or property right should have the option to repair or rebuild whenever possible. In some situations, a combination of compensation and restitution may be the most appropriate remedy and form of restorative justice.
