Constitution. 86. Just because someone is poor, the State cannot allow him to die. In fact, Government is bound to ensure that poor and vulnerable sections of society have access to treatment for rare and chronic diseases, like Gaucher especially when the prognosis is good and there is a likelihood of the patient leading a normal life. After all, health is not a luxury and should not be the sole possession of a privileged few. 87. Although obligations under Article 21 are generally understood to be progressively realizable depending on maximum available resources, yet certain obligations are considered core and non-derogable irrespective of resource constraints. Providing access to essential medicines at affordable prices is one such core obligation. 88. Since a breach of a Constitutional right has taken place, the Court is under a duty to ensure that effective relief is granted. The nature of the right infringed and the nature of the infringement provides guidance as to the appropriate relief in a particular case. 89. As health is a State subject, the present petition is disposed of with a direction to the Government of NCT of Delhi, to discharge its constitutional obligation and provide the petitioner with enzyme replacement therapy at AIIMS free of charge as and when he requires it.
