NEW YORK — Rajat Gupta, a former Goldman Sachs board member, has asked a federal appeals court to reverse his conviction on insider trading charges, arguing that a judge made a series of incorrect rulings during his trial.
“This court should reverse the convictions in view of the court’s serious evidentiary errors, which decisively tipped the scales in this case,’’ wrote Gupta’s lawyers in a brief to the US Court of Appeals for the Second Circuit in Manhattan filed late Friday.
A jury found Gupta guilty of leaking Goldman boardroom secrets to his friend, the former hedge fund manager Raj Rajaratnam. Gupta, 64, of Westport, Conn., is free on bail pending the resolution of his appeal. Among the most significant arguments is that the government should not have been allowed to use certain wiretap evidence during the trial.
On one wiretap, Rajaratnam tells a colleague, ‘‘I heard yesterday from somebody who’s on the board of Goldman Sachs that they are going to lose $2 per share.’’
