Opinion

NOT FOR PUBLICATION FILED UNITED STATES COURT OF APPEALS JUL 1 2026 MOLLY C. DWYER, CLERK U.S. COURT OF APPEALS FOR THE NINTH CIRCUIT

UNITED STATES OF AMERICA, No. 25-981 D.C. No. Plaintiff - Appellee, 3:21-cr-00455-IM-1 v. MEMORANDUM* DAVID A. KATZ,

Defendant - Appellant.

Appeal from the United States District Court for the District of Oregon Karin J. Immergut, District Judge, Presiding

Argued and Submitted June 10, 2026 Portland, Oregon

Before: CHRISTEN, HURWITZ, and BADE, Circuit Judges; Concurrence by Judge Christen.

David A. Katz appeals his convictions and sentence for conspiracy to

defraud the United States, in violation of 18 U.S.C. § 371, and for knowingly filing

false Currency Transaction Reports (CTRs), in violation of 31 U.S.C. § 5324(a)(2),

(d)(2). We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

1. Sufficient evidence supports Katz’s conspiracy conviction. See

* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. United States v. Vazquez-Hernandez, 849 F.3d 1219, 1229 (9th Cir. 2017)

(“Claims of insufficient evidence to support a jury verdict are reviewed de novo.”).

The evidence at trial established that Katz knew that his co-conspirator was using a

fake driver’s license and fake Social Security numbers. The evidence also

established that between 2014 and 2017, Check Cash Pacific, a firm for which

Katz served as a manager and compliance officer, filed hundreds of CTRs,

reporting millions of dollars of payroll checks cashed by Katz’s co-conspirator, all

of which contained the co-conspirator’s fake name and fake Social Security

numbers. A rational juror could therefore conclude that Katz agreed to defraud the

United States by obstructing the lawful functions of the Internal Revenue Service

(IRS) by deceitful or dishonest means.1 See id. (“Evidence supporting a conviction

is sufficient if, ‘viewing the evidence in the light most favorable to the prosecution,

any rational trier of fact could have found the essential elements of the crime

beyond a reasonable doubt.’” (quoting Jackson v. Virginia, 443 U.S. 307, 319

(1979))).

2. The district court did not abuse its discretion by giving deliberate

ignorance instructions on the charges of conspiracy and filing false CTRs. See

United States v. Yi, 704 F.3d 800, 804 (9th Cir. 2013) (“A district court’s decision

1 Contrary to Katz’s contention, the buyer-seller defense does not apply to his conspiracy conviction. See United States v. Lennick, 18 F.3d 814, 819–20 (9th Cir. 1994); United States v. Rodman, 776 F.3d 638, 644 (9th Cir. 2015).

2 25-981 to give a particular jury instruction is reviewed for abuse of discretion.”). “[A]

party is entitled to an instruction to help it prove its theory of the case, if the

instruction is ‘supported by law and has foundation in the evidence.’” United

States v. Heredia, 483 F.3d 913, 922 (9th Cir. 2007) (en banc) (quoting Jones v.

Williams, 297 F.3d 930, 934 (9th Cir. 2002)). “When a party requests instructions

on alternative theories, the district judge must consider the instructions separately

and determine if the evidence could support a verdict on either ground.” Id.; see

Griffin v. United States, 502 U.S. 46, 59 (1991).

At trial, the evidence established that Katz cashed millions of dollars in

checks for the scheme from approximately 2007 to 2017. Katz also set a special

rate for the scheme and regularly communicated with his co-conspirator, including

instructing him to go to a different store location “[i]f the check was over $5,000.”

The evidence also established that Katz gave his co-conspirator advance notice that

the IRS was investigating the scheme and asked his co-conspirator to provide a

recorded statement to protect him from the investigation. And Katz did not

question his co-conspirator when he filled out a new customer profile card in 2015

using a different Social Security number than the one he had been using for the

prior eight years. It was therefore reasonable for the district court to determine that

“the jury could rationally find willful blindness.” See Heredia, 483 F.3d at 922.

3. The district court did not abuse its discretion in excluding evidence

3 25-981 relating to the Woodburn fraudulent document operation under Federal Rule of

Evidence 403. See United States v. Espinoza, 880 F.3d 506, 511 (9th Cir. 2018)

(“We review the district court’s exclusion of evidence for abuse of discretion.”).

The evidence Katz sought to introduce relating to the Woodburn operation was “at

most marginally probative.” See United States v. Hitt, 981 F.2d 422, 424 (9th Cir.

1992). Indeed, there was no evidence that the fake license at issue was purchased

from the Woodburn operation or that it was a high-quality fake license. There was

also no evidence that the Woodburn operation only produced high-quality fake

licenses. Because “we are left with only speculation, not proof,” and the

“evidence, if admitted, would have created a substantial risk of confusion,” the

district court did not abuse its discretion in excluding it under Rule 403. United

States v. Espinoza-Baza, 647 F.3d 1182, 1190 (9th Cir. 2011); see id. (“Under our

precedent, even ‘a small risk of misleading the jury’ substantially outweighs the

probative value of minimally probative evidence.” (quoting Hitt, 981 F.2d at 424));

United States v. Pang, 362 F.3d 1187, 1192 (9th Cir. 2004) (“We may affirm an

evidentiary ruling on any ground supported by the record, regardless of whether

the district court relied on the same grounds or reasoning we adopt.”).

4. The district court also did not abuse its discretion in refusing to

provide a spoliation instruction based on the destruction of documents from the

investigation of the Woodburn operation. See United States v. Sivilla, 714 F.3d

4 25-981 1168, 1172 (9th Cir. 2013) (“We review a district court’s refusal to give an adverse

inference instruction, when properly raised by the appellant, for abuse of

discretion.”). Katz does not argue that the government knew that the evidence

from the Woodburn operation was relevant to this case before it was destroyed.

The government also established Katz’s knowledge through other evidence at trial,

including his co-conspirator’s use of different Social Security numbers, and Katz

had other ways to challenge his co-conspirator’s credibility. Because “the balance

between ‘the quality of the Government’s conduct and the degree of prejudice to

the accused’” does not “weigh[] in favor of the defendant,” a spoliation instruction

was not warranted. See United States v. Robertson, 895 F.3d 1206, 1213 (9th Cir.
