Joseph, a former judge of the Supreme Court of India had joined the Commission as a Member on May 27 in 2013.
"As authorised by the President of India, Justice Joseph will continue to hold the position, until the appointment of a new Chairperson in the NHRC in place of Justice K G Balakrishnan who completed his tenure on May 11," an official statement said today.
Starting of 'Open Hearings' of the complaints on the problems of Scheduled Castes and atrocities against them in different states of the country was one of his major initiatives, among several others.
He also restarted the practice of NHRC's 'Camp Sittings' in different states to dispose of pending cases in the presence of government authorities. Not only this, he also set up a committee to study and classify offences which could be heard by human rights courts.
