Furthermore it would seem to us that it is essential to keep one’s sense of proportion. With respect to the present cases, we note that the authors are asking for child benefits not only for their own children - to which they are entitled under the legislation of the Netherlands - but also for siblings, nephews and nieces, for whom they claim to have accepted responsibility and hence consider as dependants. On the basis of the information before the Committee, such demands appear to run counter to a general sense of proportion, and their denial by the government concerned cannot be considered unreasonable in view of the budget limitations which exist in every social security system. While States parties to the Covenant may wish to extend benefits to such wide-ranging categories of dependants, article 26 of the Covenant does not require them to do so. Nos. 172/1984, Broeks v. the Netherlands and 182/1984, Zwaan-de Vries v. the Netherlands.2 It is obvious that while article 26 of the Covenant postulates an autonomous right to nondiscrimination, the implementation of this right may take different forms, depending on the nature of the right to which the principle of non-discrimination is applied. With regard to the application of article 26 of the Covenant in the field of economic and social rights, it is evident that social security legislation, which is intended to achieve aims of social justice, necessarily must make distinctions. It is for the legislature of each country, which best knows the socio-economic needs of the society concerned, to try to achieve social justice in the concrete context. Unless the distinctions made are manifestly discriminatory or arbitrary, it is not for the Committee to re-evaluate the complex socio-economic data and substitute its judgement for that of the legislatures of States parties. 2 Views adopted on 9 April 1987, twenty-ninth session. 121
