Goldman Sachs wants its day in court — even if no one else is there.

A Manhattan state judge is leaning toward closing the court during testimony by Goldman Sachs employees about supposed “secret scientific material” during the Manhattan District Attorney’s case against Sergey Aleynikov, the bank’s former programmer.

Aleynikov is accused of corporate espionage, and beat a similar federal charge on appeal after spending a year in prison.

Goldman reps will make their case to close the court during a brief hearing away from the jury, Judge Daniel Conviser said Monday.

“I don’t want Goldman Sachs’ trade secrets to be broadcast to the public,” Conviser said Monday. But, he added of the allegedly stolen code from 2009: “I’d like to know why it’s still confidential today.”
