Justice P Sathasivam was on Friday sworn in as the 40th Chief Justice of India by President Pranab Mukherjee.
He took over the post from Justice Altamas Kabir, who had served as the CJI for over nine months.
Justice Sathasivam, 64, took oath in the name of God at a brief ceremony at Darbar Hall of Rashtrapati Bhavan.
Prime Minister Manmohan Singh, Vice President Hamid Ansari, United Progressive Alliance Chairperson Sonia Gandhi, Leader of the Opposition in Lok Sabha Sushma Swaraj, her Rajya Sabha counterpart Arun Jaitley, National Democratic Alliance Working Chairperson L K Advani, Communist Party of India leader D Raja and several Union ministers were present at the ceremony.
Justice Sathasivam was elevated to the Supreme Court in August, 2007. He will demit office on April 26, 2014.
Like his predecessor, Justice Sathasivam is opposed to scrapping of the present Collegium system for the appointment of Supreme Court and high court judges.
But at the same time, he has admitted that there are drawbacks in the Collegium system and efforts can be made to overcome the shortcomings to ensure transparency.
"There are drawbacks, I accept. But these drawbacks can be settled," he had said on Thursday.
Born on April 27, 1949, he enrolled as an advocate in July 1973 at Madras and was appointed as a permanent Judge of the Madras high court in January, 1996.
Later, he was transferred to the Punjab and Haryana high court in April, 2007.
Elaborating on his plan during his nearly 10-month-long tenure as Chief Justice of India, Sathasivam had said, "Delay in disposal of cases is a major issue."
"This difficulty can be overcome by enhancing judicial productivity both qualitatively and quantitatively," he said.
Justice Sathasivam said he would work towards reducing the backlog of cases by "fixing time limit for arguments, submitting written notes," etc.
Some major judgments by Justice Sathasivam include the Mumbai blasts case and that of Pakistani scientist Mohammed Khalil Chisti.
A bench of Justice Sathasivam and Justice B S Chauhan had upheld the conviction of actor Sanjay Dutt and several others in the Mumbai blasts case.
The bench had slammed Pakistan and its spy agency Inter Services Intelligence for training the perpetrators of the 1993 blasts and failing to discharge its obligation under international law to prevent terrorist attacks emanating from its territory.
"It is devastating to state that Pakistan, being a member of the United Nations, whose primary object is to maintain international peace and security, has infringed the recognised principles under international law which obligate all states to prevent terrorist attacks emanating from their territory and inflicting injuries on other states," it had said.
Another bench headed by him had set aside the conviction of Pakistani scientist Chisti.
Justice Sathasivam had also delivered the verdict in the triple murder case of Australian missionary Graham Staines. He had upheld the conviction of Dara Singh in that case.
