*567 MEMORANDUM **

Petro Krylov appeals his conviction and sentence, challenging the district court’s failure to grant his motion for a mistrial. Although the district court never formally ruled on his motion, we nonetheless treat the court’s failure to act as an implicit denial of Krylov’s motion. See United States v. Stolarz, 547 F.2d 108, 110 (9th Cir. 1976) (“[T]he entry of judgment amounts to an implicit denial of [a] motion for a new trial.”). Accordingly, we review the district court’s decision for abuse of discretion. United States v. Pineda-Doval, 614 F.3d 1019, 1036 (9th Cir. 2010).

Krylov argues that he was deprived of a fair trial because the government improperly undermined his ability to present a duress defense by challenging the link between his crimes and Russian organized crime syndicates. Specifically, he contends that the government’s cross-examination of his expert witness, in which the prosecutor questioned the link between Krylov’s crimes and a global Russian mafia, contradicted earlier representations the government made in its motion to empanel an anonymous jury, in which it contended that there was some link between Krylov’s crimes and organized crime.

The district court did not abuse its discretion by failing to grant Krylov’s motion for a mistrial. The prosecutor’s cross-examination of Krylov’s witness did not violate the doctrine of judicial estoppel because the government did not adopt a position “clearly inconsistent” with a previous one. See United States v. Ibrahim, 522 F.3d 1003, 1009 (9th Cir. 2008). Furthermore, Krylov has not demonstrated that the prosecution’s questions were designed to knowingly elicit false testimony from his witness. See United States v. Zuno-Arce, 339 F.3d 886, 889 (9th Cir. 2003) (citing Napue v. Illinois, 360 U.S. 264, 269-71, 79 S.Ct. 1173, 3 L.Ed.2d 1217 (1959)). Accordingly, we hold that the prosecution’s cross-examination of Krylov’s expert witness did not deprive him of a fair trial.

AFFIRMED.
