He said the Moscow City Court discussed the jury's acquitting Ivankov of a double murder Monday.
He said that the jury's recommendation can only be followed by the court's acquittal, according to the law.
After the 12 jurors found Ivankov innocent of the murder of two Turks, he should be released from custody in the near future.
However, prosecutors claimed they intended to appeal against the decision.
The prosecutor's office charged Ivankov and his accessory to the crime, the late authoritative criminal figure known as Sliva, of murdering the two in a Moscow restaurant in 1992.
The United States deported Ivankov to Russia on July 14, 2004 after he served out his 9-year sentence at the Allenwood federal prison in Pennsylvania.
Ivankov was found guilty in the U.S. of arranging a fraudulent marriage to keep him from being deported and extorting $3.5 million from two Russian emigrants.
