A Supreme Court bench headed by Justice Madan Lokur has transferred to the Delhi high court the four-year old Rs 50 crore defamation suit by the Delhi-based Indian Institute of Planning and Management (IIPM) that was filed in Silchar, Assam, which had in 2011 passed an injunction against the Delhi-based publisher of The Caravan magazine for a hard-hitting profile of its founder Arindam Chaudhuri.
