Legal education is an empowering tool as it adds to the intellectual faculty of an individual by imparting the knowledge of law which encompasses the domains of morality, ethics, justice, equality and so on. As a matter of fact, law does not function in isolation, it is drafted and executed to regulate and bring order to the society. Therefore, law must function in context of the socio-economic conditions existing during the time of its execution in order to be effective. It is when humanities and social sciences in law schools become highly relevant. Women form almost of the population in India and thus, understanding the nature and efficacy of their rights and entitlements, become an area of significance in the light of the principle of sustainable development. Justice, especially, Gender Justice requires the knowledge of cultural and socio-economic conditions prevailing in the society that lead to all-round marginalization of women, in order to take gender-transformative measures which target such conditions. Any law or policy in this regard, must inform the socio-economic conditions prevalent in the concerned area to which it applies. The paper seeks to analyze the importance of humanities and social sciences in law schools for effective law and policy which aims at advancing and achieving for gender justice, while highlighting the fact that lawyers, besides forming a part of legal fraternity, remain active participants of social life in various capacities ranging from civil servants, political leaders to academicians.
