The Supreme Court today directed the Archaeological Survey of India (ASI) and Municipal Corporation of Delhi (MCD) to furnish details about the steps taken by them to protect various important monuments in the Capital from being damaged and encroached upon.The monuments, regarding which the direction was issued, include mazars of famous Urdu poets Mirza Ghalib and Zauq, Dargah of Hazarat Nizamuddin Aulia, Mehrauli complex comprising Qutab minar and other heritage sites, Firoz Shah Kotla, Lal Gumbad, Tomb of Mubark Shah and the Badli ki Sarai battle ground of 1857 uprising. The issue of protection of these monuments of great historical importance against encroachments and their proper maintenance was raised in a public interest litigation (PIL) by noted environmentalist lawyer M C Mehta.Despite the Court issuing notices to the ASI, Union Government and MCD earlier, they have failed to submit their replies so far, Mehta said.
