Washington, Feb 14

The sudden death of a US Supreme Court justice has catapulted a Chandigarh-born Indian-American judge to the top of succession stakes amid a major political battle during an election year.

Srikanth Srinivasan, 48, who became a judge of the US Court of Appeals for the District of Columbia Circuit -- a traditional launching pad for Supreme Court nominees - in May 2013 after a 97-0 Senate vote was on the short-list of many in the media.

Speculation over whom President Barack Obama would nominate to replace Antonin Scalia started hours after the conservative judge\'s death Saturday morning in Texas even as top Republicans said the choice should be left to the next president.

Obama said Saturday he would nominate a successor \"in due time,\" and the Senate will get \"plenty of time .to give that person a fair hearing and a timely vote\" even as Senate Republican leaders and presidential candidates were dead set against the move.

Any list of potential replacements begins with Srinivasan, said CNN noting that Obama would likely try to find someone that at least some Republicans in Congress might find acceptable given that the opposition party controls both chambers.

Obama first nominated him to the post in 2012, and the Senate confirmed him,

97-0, in May 2013, including votes in support from Republican presidential contenders Senators Ted Cruz and Marco Rubio.

Srinivasan\'s father hailed from Mela Thiruvenkatanathapuram, a village near Tirunelveli, Tamil Nadu. His family, including two younger sisters, migrated

in the late 1960s to Lawrence, Kansas.

His father was a professor of mathematics at the University of Kansas, and his mother taught at the Kansas City Art Institute and later worked at the University of Kansas computer science department.

Srinivasan was a high school basketball star in Kansas before attending Stanford University, which he graduated from in 1989.

He was Obama\'s principal deputy solicitor general, most notably working on the successful fight against the Defence of Marriage Act.

Srinivasan also has experience on the other side of the aisle, serving as an

assistant to the solicitor general during the George W. Bush administration and as a clerk to Justice Sandra Day O\'Connor. He was once a partner in the law firm O\'Melveny & Myers.

Meanwhile, Republican Senate Majority Leader Mitch McConnell insisted the next administration should make the appointment.

But Democratic Senate Minority Leader Harry Reid said \"failing to fill this vacancy would be a shameful abdication of one of the Senate\'s most essential

Constitutional responsibilities.\"

The succession battle comes at a time when the Court is expected to hear several cases with huge political implications, including on abortion and affirmative action.

US President Barack Obama said he planned to nominate a new Supreme Court justice after the death of Justice Antonin Scalia, a step promising to be another partisan jockeying with Republican rivals.

\"Today is a time to remember Justice Scalia\'s legacy. I plan to fulfill my constitutional responsibility to nominate a successor in due time,\" Xinhua news agency quoted Obama as saying on Saturday.

\"There will be plenty of time for me to do so and for the Senate to fulfill its responsibility to give that person a full hearing and timely vote.\"

According to the ocal media, Scalia died in his sleep during his trip to Texas. The cause of his death was not available at the moment, but early reports suggested that he apparently died of natural causes.

The first Italian-American to sit on the country\'s highest court, Scalia, 79, was the leading conservative voice on the court and his death was expected to set off a prolonged fight over who would succeed him.

Shortly after the news of Scalia\'s death, Senate Majority Leader Republican Mitch McConnell, who sets the Senate schedule for confirmation of the Supreme Court nominations, said Scalia should not be replaced till after the presidential election.

\"The American people should have a voice in the selection of their next Supreme Court Justice,\" said McConnell in a statement. \"Therefore, this vacancy should not be filled till we have a new President.\"

Calling it \"unprecedented\" for the Supreme Court to go a year with a vacant seat, Senate Minority Leader Democrat Harry Reid blasted McConnell\'s suggestion as \"a shameful abdication of one of the Senate\'s most essential Constitutional responsibilities\".

With the absence of Justice Scalia, a former lynchpin of a conservative majority of the Supreme Court, the eight remaining justices are evenly divided, a fact which could change the ruling on contentious issues, including Obama\'s Clean Power Plan and executive actions on immigration.

The last time a major shift in the country\'s highest court\'s makeup occurred was in 1991 when former US President George H.W. Bush nominated conservative Justice Clarence Thomas to succeed liberal Justice Thurgood Marshall. Since then, a five-conservative majority in the the Supreme Court has held steady.
