In addition to political, economic and social measures, law is one of the principal means of ensuring equality in dignity and rights among individuals, and of curbing any propaganda, any. form of organization or any practice which is based on ideas or theories referring to the alleged superiority of racial or ethnic groups or which seeks to justify or encourage racial hatred and discrimination in any form. States should adopt such legislation as is appropriate to this end and see that it is given effect and applied by all their services, with due regard to the principles embodied in the Universal Declaration of Human Rights. Such legislation should form part of a political, economic and social framework conducive to its implementation. Individuals and other legal entities, both public and private, must conform with such legislation and use all appropriate means to help the population as a whole to understand and apply it.
