E/C.12/1994/13 page 5 necessary, seek international cooperation and assistance. In the latter respect, international cooperation in accordance with articles 22 and 23 of the Covenant is likely to be a particularly important element in enabling some developing countries to fulfil their obligations under the Covenant. 14. In addition, it has been consistently acknowledged by the international community that policy-making and programme implementation in this area should be undertaken on the basis of close consultation with, and involvement of, representative groups of the persons concerned. For this reason, the Standard Rules recommend that everything possible be done to facilitate the establishment of national coordinating committees, or similar bodies, to serve as a national focal point on disability matters. In doing so, Governments should take account of the 1990 Guidelines for the Establishment and Development of National Coordinating Committees on Disability or Similar Bodies. 15/ III. THE OBLIGATION TO ELIMINATE DISCRIMINATION ON THE GROUNDS OF DISABILITY 15. Both de jure and de facto discrimination against persons with disabilities have a long history and take various forms.

The effects of disability-based discrimination have been particularly severe in the fields of education, employment, housing, transport, cultural life, and access to public places and services. 16. Despite some progress in terms of legislation over the past decade, 16/ the legal situation of persons with disabilities remains precarious. In order to remedy past and present discrimination, and to deter future discrimination, comprehensive anti-discrimination legislation in relation to disability would seem to be indispensable in virtually all States parties. Such legislation should not only provide persons with disabilities with judicial remedies as far as possible and appropriate, but also provide for social-policy programmes which enable persons with disabilities to live an integrated, self-determined and independent life. 17. Anti-discrimination measures should be based on the principle of equal rights for persons with disabilities and the non-disabled, which, in the words of the World Programme of Action concerning Disabled Persons, "implies that the needs of each and every individual are of equal importance, that these needs must be made the basis for the planning of societies, and that all
