Article 21, read with Articles 39(e), 41, 43, 48A and all related Articles and fundamental human rights to make the life of the workman meaningful and purposeful with dignity of person......... It would thus be clear that in an appropriate case, the Court would give appropriate directions to the employer, be it the State or its undertaking or private employer to make the right to life meaningful; to prevent pollution of work place; protection of the environment; protection of the health of the workman or to preserve free and unpolluted water for the safety and health of the people. The authorities or even private persons or industry are bound by the directions issued by this Court under Article 32 and Article 142 of the Constitution." (emphasis supplied). 61. It is pertinent to mention that judgments of Supreme Court in Pt. Parmanand Katara (supra) and Paschim Bangal Khet Mazdoor Samity and Others (supra) have not been overruled till date. In fact, in the subsequent Constitution Bench judgment in the case of Confederation of Ex servicemen Associations and Ors. (supra) the Supreme Court reiterated that right to medical aid is a fundamental right of all citizens guaranteed by Article 21. The Constitution Bench only held that the contributory scheme framed by the Government qua ex-service men, under which they had to pay one time contribution, was constitutionally valid. In the opinion of this Court, if a class or category of its citizens can afford to pay or partially pay for their medical treatment because of their economic background, Government can certainly frame a contributory scheme for medical treatment.
