The HC yesterday questioned the legality of Dhaka University authorities' decision to demote its teacher Samia Rahman on charge of plagiarism in a research paper, following a writ petition by her.

On January 28, Samia, associate professor of DU's Mass Communication and Journalism, was demoted to assistant professor by a decision by DU syndicate. Samia's lawyer Hassan MS Azim said the research paper in question was not prepared by her and did not have her signature on it.
