54-year-old Rajaratnam's prison sentence is scheduled to begin on December 5 at a federal penitentiary in Massachusetts.
A three-judge panel in the US Court of Appeals for the Second Circuit is reviewing a trial court judgement that had refused to grant bail to Sri Lanka-born Rajaratnam while he appealed his conviction.
The panel reserved its judgement and is expected to announce it before the end of the week.
During yesterday's hearing, the judges focussed on whether Rajaratnam is a flight risk if he is allowed to remain free on bail.
"Wouldn''t he rather be living as a centimillionaire in his own country rather than as a convict in a jail?" Judge Dennis Jacobs asked Rajaratnam's lawyer Patricia Millett. Millett argued that her client cannot fly to Sri Lanka as his family lives in the US and his passport had been surrendered to authorities.
She also put forth the point that Rajaratnam''s health is falling and he needs a kidney transplant. He is required to take 13 medications a day and would not get the required medical care in Sri Lanka.
