E/C.12/2000/4 page 14 III. VIOLATIONS 46. When the normative content of article 12 (Part I) is applied to the obligations of States parties (Part II), a dynamic process is set in motion which facilitates identification of violations of the right to health. The following paragraphs provide illustrations of violations of article 12. 47. In determining which actions or omissions amount to a violation of the right to health, it is important to distinguish the inability from the unwillingness of a State party to comply with its obligations under article 12. This follows from article 12.1, which speaks of the highest attainable standard of health, as well as from article 2.1 of the Covenant, which obliges each State party to take the necessary steps to the maximum of its available resources. A State which is unwilling to use the maximum of its available resources for the realization of the right to health is in violation of its obligations under article 12. If resource constraints render it impossible for a State to comply fully with its Covenant obligations, it has the burden of justifying that every effort has nevertheless been made to use all available resources at its disposal in order to satisfy, as a matter of priority, the obligations outlined above. It should be stressed, however, that a State party cannot, under any circumstances whatsoever, justify its non-compliance with the core obligations set out in paragraph 43 above, which are nonderogable. 48. Violations of the right to health can occur through the direct action of States or other entities insufficiently regulated by States. The adoption of any retrogressive measures incompatible with the core obligations under the right to health, outlined in paragraph 43 above, constitutes a violation of the right to health. Violations through acts of commission include the formal repeal or suspension of legislation necessary for the continued enjoyment of the right to health or the adoption of legislation or policies which are manifestly incompatible with pre-existing domestic or international legal obligations in relation to the right to health. 49. Violations of the right to health can also occur through the omission or failure of States to take necessary measures arising from legal obligations. Violations through acts of omission include the failure to take appropriate steps towards the full realization of everyone’s right to the enjoyment of the highest attainable standard of physical and mental health, the failure to have a national policy on occupational safety and health as well as occupational health services, and the failure to enforce relevant laws. Violations of the obligation to respect 50. Violations of the obligation to respect are those State actions, policies or laws that contravene the standards set out in article 12 of the Covenant and are likely to result in bodily harm, unnecessary morbidity and preventable mortality. Examples include the denial of access to health facilities, goods and services to particular individuals or groups as a result of de jure or de facto discrimination; the deliberate withholding or misrepresentation of information vital to health protection or treatment; the suspension of legislation or the adoption of laws or policies that interfere with the enjoyment of any of the components of the right to health; and the failure of the State to take into account its legal obligations regarding the right to health when entering into bilateral or multilateral agreements with other States, international organizations and other entities, such as multinational corporations.
