"While article 2 limits the scope of the rights to be protected against discrimination to those provided for in the Covenant, article 26 does not specify such limitations. That is to say, article 26 provides that all persons are equal before the law and are entitled to equal protection of the law without discrimination, and that the law shall guarantee to all persons equal and effective protection against discrimination on any of the enumerated grounds. In the view of the Committee, article 26 does not merely duplicate the guarantee already provided for in article 2 but provides in itself an autonomous right. It prohibits discrimination in law or in fact in any field regulated and protected by public authorities. Article 26 is therefore concerned with the obligations imposed on States parties in regard to their legislation and the application thereof. Thus, when legislation is adopted by a State party, it must comply with the requirement of article 26 that its content should not be discriminatory. In other words, the application of the principle of non-discrimination contained in article 26 is not limited to those rights which are provided for in the Covenant."
