Economist Prabhat Patnaik, who is an emeritus professor with Jawaharlal Nehru University, has been asked by the university not to address students at prohibited areas on the campus.

Patnaik, who began teaching at the university in 1974 when it just a few years old, was sent a letter by the registrar on Thursday telling him it was “unfortunate” that he did not “care to respect the rules of the university”.

“It is expected from you that such violation of rules is not repeated in the future,” the letter from registrar Pramod Kumar said.

JNU students’ union had on August 4 organised a pubic talk on “The idea of a university: democracy, resistance, and future challenges” where Patnaik along with former JNU professors Harbans Mukhia, and Chaman Lal, and a journalist addressed the students.
