In the context of the Constitution of India, P.B. Gajendragadkar, former Chief Justice of India, said: “The concept of social justice is (thus) a revolutionary concept which gives meaning and significance to the democratic way of life and makes the rule of law dynamic. It is this concept of social justice which creates in the minds of the masses of this country a sense of participation in the glory of India’s political freedom” He further adds, “Social justice must be achieved by adopting necessary and reasonable measures with courage, wisdom, foresight, sense of balance and fairplay to all the interests concerned. That shortly stated, is the concept of social justice and its implications. If eternal vigilance is the price for national liberty, it is equally the price for sustaining individual freedom and liberty in welfare state”. Now but us discuss various theories of social justice.
