coercion to have or to adopt a religion or belief and the liberty of parents and guardians to ensure religious and moral education cannot be restricted. In interpreting the scope of permissible limitation clauses, States parties should proceed from the need to protect the rights guaranteed under the Covenant, including the right to equality and non-discrimination on all grounds specified in articles 2, 3 and 26. Limitations imposed must be established by law and must not be applied in a manner that would vitiate the rights guaranteed in article 18. The Committee observes that paragraph 3 of article 18 is to be strictly interpreted: restrictions are not allowed on grounds not specified there, even if they would be allowed as restrictions to other rights protected in the Covenant, such as national security. Limitations may be applied only for those purposes for which they were prescribed and must be directly related and proportionate to the specific need on which they are predicated. Restrictions may not be imposed for discriminatory purposes or applied in a discriminatory manner. The Committee observes that the concept of morals derives from many social, philosophical and religious traditions; consequently, limitations on the freedom to manifest a religion or belief for the purpose of protecting morals must be based on principles not deriving exclusively from a single tradition.
