The Law School is one of the earliest faculties established in the Banaras Hindu University. Mahamana Pandit Madan Mohan Malaviya, the founder of this university, served for many years as Dean of the Law School. Legal luminaries like Sir Ras Behari Ghosh and Sir Tej Bahadur Sapru were the earlier Deans.

The Law School has been a pioneer in introducing the full-time three-year LL.B. course and two-year full-time LL.M. program. It has taken a lead and is perhaps the only law school in India to introduce the two years full-time special courses of LL.M. in Human Rights and Duties Education. It is the first law school in India to introduce clinical legal education and legal aid program to cater to the needs of the poor.

Law School BHU was one of the six universities in India to start Clinical Legal Services. The model developed by the Law School has been judged as the best model by Hon’ble Mr. Justice P. N. Bhagwati, former Chief Justice of India.
