Justice Bhagwati in the case of National Textiles Workers Union v P.R.Ramakrishnan need to be set out. They are: “ We cannot allow the dead hand of the past to stifle the growth of the living present. Law cannot stand still; it must change with the changing social concepts and values. If the bark that protects the tree fails to grow and expand along with the tree, it will either choke the tree or if it is a living tree it will shed that bark and grow a living bark for itself. Similarly, if the law fails to respond to the needs of changing society, then either it will stifle the growth of the society and choke its progress or if the society is vigorous enough, it will cast away the law, which stands in the way of its growth. Law must therefore constantly be on the move adapting itself to the fast-changing society and not lag behind

Judge must be a jurist endowed with the legislator's wisdom, historian's search for truth, prophet’s vision, and capacity to respond to the needs of the present, resilience to cope with the demands of the future and to decide objectively disengaging himself/herself from every personal influence or predilections. Therefore, the judges should adopt purposive interpretation of the dynamic concepts of the Constitution and the Act with its interpretative armoury to articulate the felt necessities of the time. The judge must also bear in mind that social legislation is not a document for fastidious dialects but a means of ordering the life of the people. To construe law one must enter into its spirit, its setting and history. Law should be capable of expanding freedoms of the people and the legal order can, weighed with utmost equal care, be made to provide the underpinning of the highly inequitable social order
