51. In fact, in State of Maharashtra Vs. Chandrabhan, AIR 1983 SC 803 the Supreme Court held that right to life, enshrined in Article 21 means something more than survival or animal existence. It includes all those aspects of life which go to make a man's life meaningful, complete and worth living. That which alone can make it possible to live must be declared to be an integral component of the right to life. 52. The human right to health is also recognized in numerous international instruments. Article 25.1 of the Universal Declaration of Human Rights affirms: "Everyone has the right to a standard of living adequate for the health of himself and of his family, including food, clothing, housing and medical care and necessary social services". The International Covenant on Economic, Social and Cultural Rights provides the most comprehensive article on the right to health in international human rights law. In accordance with article 12.1 of the Covenant, States parties recognize "the right of everyone to the enjoyment of the highest attainable standard of physical and mental health", while article 12.2 enumerates, by way of illustration, a number of steps to be taken by the States parties to achieve the full realization of this right. Article 12.2 reads as under:"2. The steps to be taken by the States Parties to the present Covenant to achieve the full realization of this right shall include those necessary for : (a) The provision for the reduction of the stillbirth-rate and of infant mortality and for the healthy development of the child; (b) The improvement of all aspects of environmental and industrial hygiene; (c) The prevention, treatment and control of epidemic, endemic, occupational and other diseases; W.P.(C) 7279/2013 Page 23 of 41
