MEMORANDUM

Kenny Bukola Oriyomi appeals from his conviction of three counts of bank fraud, three counts of money laundering, and one count of failure to file a tax return. He contends that the district court erred in its evidentiary rulings and its instructions to the jury. We have jurisdiction pursuant to 28 U.S.C. § 1291 .

I

Oriyomi asserts that the district court abused its discretion in permitting cross-examination testimony regarding specific instances of conduct pursuant to Rule 608(b) of the Federal Rules of Evidence because they were unfairly prejudicial pursuant to Rule 403 of the Federal Rules of Evidence. He further asserts that the evidence created an inference of the existence of extrinsic evidence not allowed under Rule 608(b).

This Court has adopted a two-part test to determine whether a district court abused its discretion. United States v. Hinkson, 585 F.3d 1247, 1261 (9th Cir.2009) (en banc).

Id. at 1261-62 (quoting Anderson v. City of Bessemer City, 470 U.S. 564, 577 , 105 S.Ct. 1504 , 84 L.Ed.2d 518 (1985)).

Rule 608(b) allows specific instances of conduct of a witness to be inquired into on cross-examination if probative of truthfulness or untruthfulness. Under this rule, prosecutors may cross-examine witnesses about documents so long as they do not enter the documents as extrinsic evidence. Under Rule 403, however, relevant evidence may be excluded if its “probative value is substantially outweighed by the danger of unfair prejudice.” Fed.R.Evid. 403 (emphasis added). “Evidence of prior frauds is considered probative of the witness’s character for truthfulness or untruthfulness” and admissible as prior conduct pursuant to Rule 608(b). United States v. Gay, 967 F.2d 322, 328 (9th Cir.1992). Oriyomi signed his Social Security card applications, his petition for bankruptcy, and his tax returns under penalty of perjury, and thus they are evidence of his untruthfulness and were admissible on cross-examination pursuant to Rules 608(b) and 408.

Based on its extensive review of the filings of the parties and the arguments at the hearing, the district court properly weighed the probative value of the Rule 608(b) evidence against the danger of unfair prejudice to Oriyomi.

II

Oriyomi also asserts that the district court erred in instructing the jury with regard to the “willfulness” element of the charge of failure to file a tax return. He further contends that there is no evidence in the record that he either earned enough to necessitate a tax return or that he knew what minimum income would require a tax return to be filed.

“[I]f the Government proves actual knowledge of the pertinent legal duty, the prosecution, without more, has satisfied the knowledge component of the willfulness requirement.” Cheek v. United States, 498 U.S. 192, 202 , 111 S.Ct. 604 , 112 L.Ed.2d 617 (1991). At trial, Oriyomi testified that he helped prepare tax returns for a medical supply company. Ori-yomi further testified that he would have filed a tax return for 2004, but that he was hospitalized between April and August 2005. He also asserted on direct examination that “normally I would have filed because I had — it’s just something that I— that I know that I have to do.” (emphasis added). Because of Oriyomi’s concession that he knew he had to file a tax return, any error in the district court’s failure expressly to inform the jury that it must find he knew he had a legal duty to do so was harmless.

AFFIRMED.
