NOT FOR PUBLICATION FILED UNITED STATES COURT OF APPEALS APR 30 2026 MOLLY C. DWYER, CLERK U.S. COURT OF APPEALS FOR THE NINTH CIRCUIT

UNITED STATES OF AMERICA, No. 24-5919 D.C. No. Plaintiff - Appellee, 5:22-cr-00251-EJD-1 v. MEMORANDUM* BRIAN BRODERICK,

Defendant - Appellant.

Appeal from the United States District Court for the Northern District of California Edward J. Davila, District Judge, Presiding

Submitted April 24, 2026** San Francisco, California

Before: GOULD, NGUYEN, and BENNETT, Circuit Judges.

Appellant Brian Broderick challenges his conviction for transmitting a

communication containing a threat to injure in violation of 18 U.S.C. § 875(c). “We

review a district court’s evidentiary rulings for abuse of discretion.” United States v.

* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). Perez, 962 F.3d 420, 434 (9th Cir. 2020). When “considering a challenge to a

conviction based on sufficiency of the evidence,” we view all evidence presented at

trial “in the light most favorable to the prosecution,” presuming “that the trier of fact

resolved” all conflicting inferences “in favor of the prosecution,” and deferring to

that resolution. United States v. Nevils, 598 F.3d 1158, 1164 (9th Cir. 2010) (en

banc). And we will uphold the conviction if “this evidence, so viewed, is adequate

to allow ‘any rational trier of fact [to find] the essential elements of the crime beyond

a reasonable doubt.’” Id. (quoting Jackson v. Virginia, 443 U.S. 307, 319 (1979)).

But in criminal threat cases, we also “conduct an independent review of the record to

determine whether the facts as found by the jury establish the core constitutional fact”

as to whether the defendant’s speech constituted a true threat. United States v.

Hanna, 293 F.3d 1080, 1088 (9th Cir. 2002); see also Planned Parenthood of

Columbia/Willamette, Inc. v. Am. Coal. of Life Activists, 290 F.3d 1058, 1070 (9th

Cir. 2002) (en banc) (“We will consider the undisputed facts as true, and construe the

historical facts, the findings on the statutory elements, and all credibility

determinations in favor of the prevailing party.”). Applying these standards, we

AFFIRM Broderick’s conviction.

1. Broderick waived the issue of whether it was proper to exclude Dr.

Greene’s testimony based on Broderick’s refusal to submit to a psychiatric

assessment by a government expert. “An appellate court will not consider issues not

2 24-5919 properly raised before the district court,” and “[t]he ‘withdrawal of an objection is

tantamount to a waiver of an issue for appeal.’” CDN Inc. v. Kapes, 197 F.3d 1256,

1258 (9th Cir. 1999) (quoting Slaven v. Am. Trading Transp. Co., 146 F.3d 1066,

1069 (9th Cir. 1998)).

Here, Broderick timely provided notice of his intent to introduce Dr. Greene’s

expert testimony under Federal Rule of Criminal Procedure (“Rule”) 12.2(b). The

prosecution then moved for an order allowing a “mental health professional

designated by the government [to] conduct an examination of defendant Brian

Broderick and provide a report of the examination to the Court and the parties” under

Rule 12.2(c)(1)(B). But before the court could rule on the government’s motion,

Broderick withdrew his 12.2(b) notice, thus withdrawing his “intent to introduce

expert evidence regarding his mental condition.” Broderick also requested that the

court “deny the Government’s motion for evaluation under Rule 12.2 as moot.”

Accepting that request, the district court denied the government’s motion as moot.

By withdrawing his 12.2(b) notice and successfully requesting that the court

deny the government’s examination motion as moot, Broderick effectively waived

his challenge to the exclusion of Dr. Greene’s testimony. This is because the trial

court could not rule on the mooted motion to order an examination. See Arizona v.

Components Inc., 66 F.3d 213, 217 (9th Cir. 1995) (“Although there is no bright-

line rule to determine whether a matter has been raised below, ‘a workable

3 24-5919 standard . . . is that the argument must be raised sufficiently for the trial court to rule

on it.’” (quoting In re E.R. Fegert, Inc., 887 F.2d 955, 957 (9th Cir. 1989))); see also

United States v. Macias, 789 F.3d 1011, 1017 n.3 (9th Cir. 2015) (holding we have

discretion to find waiver even where appellee has “fail[ed] to assert it”).

2. The district court did not “err[] by preventing [Broderick’s therapist] Mr.

Mailes from testifying about ‘any observations made as the result of his training as

a therapist’ or ‘any instance whereby [Broderick]’s behavior led Mr. Mailes to any

medical conclusion based on his training as a therapist.’” Broderick moved to admit

Mailes as a lay witness, so the district court allowed Mailes to “testify as a lay

witness as to his observations of [Broderick]’s behavior using language which is

commonly understood as lay nomenclature, such as paranoid and delusional.” The

basis of such an “opinion is ‘just familiarity with the subjects,’” so “it is proper lay

opinion under [Federal] Rule [of Evidence] 701.” See United States v. Holmes, 163

F.4th 547, 560 (9th Cir. 2025) (quoting Perez, 962 F.3d at 437). On the other hand,

testimony based on Mailes’s specialized training as a Licensed Marriage and Family

therapist, including observations, diagnoses, or medical conclusions made on that

basis, or the use of language “which would suggest a diagnosis,” would rely on

Mailes’s “technical or specialized knowledge” rather than “just familiarity with the

subjects” or solely matters he “personally observe[d],” and therefore fall outside the

scope of lay witness testimony. See id.

4 24-5919 Nor did the district court err by ruling that Mailes could not identify himself

as Broderick’s therapist or testify about “any information which would reveal to the

jury his role as [Broderick]’s treating therapist.” Identifying Mailes as Broderick’s

therapist would risk lending an air of expertise to his lay testimony that Broderick

appeared delusional and paranoid, which the district court was concerned to prevent.

Under the broad latitude a district court enjoys to “exclude relevant evidence if its

probative value is substantially outweighed by a danger of . . . confusing the issues

[or] misleading the jury,” Fed. R. Evid.
