In a written reply to a question, he said "there has been no delay in disposing of alleged human rights violation cases. Further, all the cases where investigations have been completed were found to be false."
Out of the total complaints, 25 were registered in North East and five in Jammu and Kashmir.
Replying to a question on delay in construction of Indigenous Aircraft Carrier for the Indian Navy, Antony said "there has been a slippage in the construction schedule of IAC being built at the Cochin Shipyard Limited."
The complexity of the project and this being the first ship of its kind being built in India has led to timelines being extended, the minister said.
As per the phase-I contract, the first launch of the ship was envisaged in October, 2010.
"Due to delays in receipt of steel plates and pre-launch equipment like diesel alternators and gearboxes, the launch of the ship is now expected in 2013. Delivery of the ship is presently envisaged in 2018," Antony told the House.
