The Supreme Court Monday adjourned by four weeks the hearing on a plea seeking directions for a caste-based census for the Other Backward Classes (OBCs) in the upcoming Census. A bench of Justices L Nageswara Rao and B R Gavai deferred the hearing after senior advocate Gopal Shankarnarayanan informed it that a similar petition is pending before another bench as well. "List after four weeks along with Writ Petition," the bench said.
