Appeal from the United States District Court
for the District of Idaho
Raymond E. Patricco, Magistrate Judge, Presiding
Argued and Submitted November 4, 2025
Portland, Oregon
Before: M. SMITH, NGUYEN, and H.A. THOMAS, Circuit Judges.
Petitioner Larry Severson was convicted of poisoning and murdering his wife,
Mary. Following direct appeal and requests for post-conviction relief, Severson
petitioned the district court for a writ of habeas corpus. The magistrate judge denied

his petition but issued a certificate of appealability (COA) on Severson’s claim that
his trial attorneys rendered ineffective assistance of counsel by failing to object to
improper closing remarks by the prosecutor. Severson now appeals the magistrate
judge’s order rejecting that claim. He also requests that we expand the COA so he
can challenge the prosecutor’s alleged misconduct on due process grounds.
With jurisdiction under 28 U.S.C. §§ 1291 and 2253, we affirm the magistrate
judge’s denial of habeas relief on both the certified and uncertified issues.
The parties are familiar with the facts, so we do not recount them here except
as necessary to provide context for our ruling.
1. Respondents challenge the magistrate judge’s order rejecting their
theory that Severson’s habeas petition is time-barred. However, the magistrate judge
was correct. Severson filed his petition in August 2020, just four months after the
Idaho Court of Appeals resolved his 2018 application for post-conviction relief. See
State v. Severson, No. 46343, 2020 WL 1899821, at *1 (Idaho Ct. App. Apr. 17,
2020). Because “[t]he time during which a properly filed application for State post-
conviction . . . review . . . is pending shall not be counted toward any period of
limitation,” Severson’s petition was filed well within the applicable “1-year period
of limitation.” 28 U.S.C. § 2244(d).
But according to Respondents, Severson’s 2018 application was not “properly
filed,” as it was procedurally barred by Idaho Code § 19-4908. And so, they argue,
2 23-3187 & 23-3247
the limitations clock began ticking in July 2019, rendering Severson’s August 2020
petition untimely. Respondents are mistaken. A procedural bar to relief, such as a
state law barring claims “previously determined on the merits,” does not render a
post-conviction application improperly filed under § 2244(d). Artuz v. Bennett, 531
U.S. 4, 10–11 (2000) (quoting N.Y. Crim. Proc. Law § 440.10(2)). Idaho’s statute
barring post-conviction relief based on “ground[s] finally adjudicated” in a prior
application falls neatly within this doctrine. Idaho Code § 19-4908. The statute sets
limits on the “claims” an applicant can advance without purporting to impose any
“condition to filing.” Artuz, 531 U.S. at 9, 11. Severson’s petition was thus
“properly filed” within the meaning of § 2244(d).
Although we have twice noted that “improper successive [applications]” do
not toll the limitations period under § 2244(d)(2), we made those comments in
dicta—without assessing their congruity with Artuz or examining the state-law
procedural bars at issue. See Porter v. Ollison, 620 F.3d 952, 958 (9th Cir. 2010);
Blackman v. Cisneros, 122 F.4th 377, 384 & n.3 (9th Cir. 2024) (quoting Porter,
620 F.3d at 958). Neither case vitiates our duty to apply Artuz to the facts before us.
2. Severson raises a threshold issue of his own. He argues that the
Antiterrorism and Effective Death Penalty Act (AEDPA), which governs claims for
federal habeas relief by state prisoners, “runs afoul of Article III” following the
Supreme Court’s decision in Loper Bright Enterprises v. Raimondo, 603 U.S. 369
3 23-3187 & 23-3247
(2024). Severson forfeited this challenge, however, as he failed to raise the issue in
his opening brief. See Transamerica Life Ins. Co. v. Arutyunyan, 93 F.4th 1136,
1146 (9th Cir. 2024).
3. When denying Severson’s habeas petition, the magistrate judge
certified for appeal the question whether Severson’s trial attorneys provided
ineffective assistance of counsel in violation of the Sixth Amendment. To prevail
on this claim, Severson must show that his “counsel’s performance was deficient,”
and “that the deficient performance prejudiced the defense.” Strickland v.
Washington, 466 U.S. 668, 687 (1984). The “deficiency” element asks whether the
quality of representation fell “below an objective standard of reasonableness.” Id.
at 688. In making this assessment, we must be “highly deferential” to counsel’s
decisions. Id. at 689. The “prejudice” element asks whether “there is a reasonable
probability that, but for counsel’s unprofessional errors, the result of the proceeding
would have been different.” Id. at 694. A reasonable probability is a “substantial,”
not merely “conceivable,” probability. Cullen v. Pinholster, 563 U.S. 170, 189
(2011) (quoting Harrington v. Richter, 562 U.S. 86, 112 (2011)).
On habeas review, AEDPA restricts relief to cases where the state court’s
decision “was contrary to, or involved an unreasonable application of, clearly
established Federal law, as determined by the Supreme Court.” 28 U.S.C.
§ 2254(d)(1). This standard is met only if no “fairminded jurist[] could disagree”
4 23-3187 & 23-3247
that the state court contradicted Supreme Court precedent. Harrington, 562 U.S at
102 (quoting Yarborough v. Alvarado, 541 U.S. 652, 664 (2004)). Since Strickland
and AEDPA “are both highly deferential” standards, when both apply, “review is
doubly so.” Id. at 105 (cleaned up). At this juncture, we review “the last reasoned
state court decision.” Balbuena v. Sullivan, 980 F.3d 619, 629 (9th Cir. 2020). But
if the “state court has not reached the merits” of a given issue, we “review it de
novo.” Pirtle v. Morgan, 313 F.3d 1160, 1167 (9th Cir. 2002).
Severson contends that his counsel rendered deficient performance by failing
to object to certain comments by the prosecutor, including that his expert was “a
very credible individual, with nothing to lose,” and that “[t]here is no innocence in
this courtroom except the innocence of Mary Severson.” We agree with Severson
that these and other remarks were inappropriate and objectionable, and should never
have been uttered. See, e.g., United States v. Sanchez, 176 F.3d 1214, 1224 (9th Cir.
1999) (“As a general rule, a prosecutor may not express” her “belief in the credibility
of government witnesses.”); Ford v. Peery, 999 F.3d 1214, 1224, 1227 (9th Cir.
2021) (concluding that a prosecutor misstated the law when remarking to the jury
“that the presumption of innocence was ‘over’”).
However, that does not necessarily mean that Severson’s attorneys’
performance fell beneath an “objective standard of reasonableness.” Strickland, 466
U.S. at 688. We owe deference both to Severson’s counsel and to the Idaho Court
5 23-3187 & 23-3247
of Appeals, which concluded that Severson’s counsel was not deficient (except,
perhaps, with respect to the vouching comment). See Severson v. State, No. 45780,
2019 WL 1787315, at *6 (Idaho Ct. App. Apr. 24, 2019) (Severson IV).1 Ultimately,
we need not review the Idaho court’s “deficiency” determinations comment-by-
comment because, even presuming that counsel was duty-bound to object to each of
the challenged remarks, Severson’s Strickland claim still fails on the prejudice
prong.2
Severson is correct that no Idaho court analyzed the impact of these statements
on the verdict cumulatively, as none found more than one instance of deficiency to
cumulate. See State v. Severson, 215 P.3d 414, 441–43 (Idaho 2009) (Severson I);
Severson IV, 2019 WL 1787315 at *7. However, this point is of no help to him.
Analyzing the issue de novo, Pirtle, 313 F.3d at 1167, there is no “reasonable
probability” that “the result of the proceeding would have been different” had
1
Making this argument more difficult for Severson is a line of cases
explaining that, given the numerous sound reasons an attorney might “refrain from
objecting during . . . closing argument, absent egregious misstatements, the failure
to object during closing argument” generally falls “within the ‘wide range’ of
permissible professional legal conduct.” United States v. Necoechea, 986 F.2d 1273,
1281 (9th Cir. 1993) (quoting Strickland, 466 U.S. at 689); see also, e.g., United
States v. Mejia-Mesa, 153 F.3d 925, 931 (9th Cir. 1998) (“[A] few missed objections
alone, unless on a crucial point, do not rebut the strong presumption” that counsel’s
performance was “reasonable.”).
2
We assume without deciding that the “cumulative error” doctrine is “clearly
established” for AEDPA purposes, such that the Court must cumulate the Strickland
deficiencies and analyze their total impact on the verdict.
6 23-3187 & 23-3247
Severson’s attorneys objected to the challenged remarks. Strickland, 466 U.S. at
694. The 17-day trial record is replete with uncontroverted evidence of Severson’s
guilt. Some of the most incriminating examples include the unexplained testimony
(1) that Mary’s weight-loss pills were laced with drain cleaner and that the packaging
had been tampered with; (2) that residue from trash seized at Severson’s workplace
was consistent with the same drain cleaner; (3) that Severson did not call 911 after
supposedly finding his wife unresponsive, even though he was the only other person
home; (4) that he told others he wished to divorce Mary, but was financially
incapable of doing so because their home, business, and cars were all in her name;
(5) that he planned for her death, including (a) by falsely telling others that Mary
had cancer, but telling them not to mention the cancer to her, and (b) by getting
engaged to another woman and making plans for her to move into his home (which
was in Mary’s name); (6) that he sought out Mary’s life-insurance policy mere hours
after her death, falsely claiming that his mother-in-law had inquired about it; (7) that
he lied to his daughter-in-law and hospital staff about Mary taking sleeping pills,
although he had personally refilled her prescription the day before; and (8) that
authorities found a bag of sleeping pills in his house, concealed in a hat labeled
“Dad.”
In addition, the trial judge repeatedly instructed the jury that the prosecutor’s
arguments were not evidence, and that the jury’s verdict must rest on evidence alone.
7 23-3187 & 23-3247
Courts “generally presume that jurors follow” such instructions. Penry v. Johnson,
532 U.S. 782, 799 (2001).
The combination of these factors renders defense counsel’s passivity during
closing arguments harmless. See Featherstone v. Estelle, 948 F.2d 1497, 1507 (9th
Cir. 1991) (concluding that counsel’s non-objections did not prejudice petitioner
where a “substantial amount of . . . evidence pointed squarely at his guilt, and the
jury was properly advised that counsel’s statements were merely argument, not
evidence”); Cunningham v. Wong, 704 F.3d 1143, 1159 (9th Cir. 2013) (similar).
4. Beyond his Strickland claim, Severson asks that we expand the COA,
so he can assert a due process claim based on the prosecutor’s misconduct.3 We
grant his request but hold that this claim also fails for lack of prejudice.
To show a due process violation, it “is not enough that the prosecutors’
remarks were undesirable or even universally condemned.” Darden v. Wainwright,
477 U.S. 168, 181 (1986). Instead, the “due process analysis in cases of alleged
prosecutorial misconduct” centers on “the fairness of the trial.” Smith v. Phillips,
455 U.S. 209, 219 (1982). A fair trial is one “resulting in a verdict worthy of
confidence.” Kyles v. Whitley, 514 U.S. 419, 434 (1995). Severson’s burden is to
show “a reasonable probability” that the misconduct “rendered the trial

“resolution” not “reasonably debatable.”
8 23-3187 & 23-3247
fundamentally unfair.” Ford, 999 F.3d at 1225 (quoting Deck v. Jenkins, 814 F.3d
954, 985 (9th Cir. 2016)).
The bar for such claims is high. In Darden, the Supreme Court rejected a due
process challenge where the prosecutor referred to the defendant as an “animal,”
mentioned the death penalty in a guilt-phase proceeding, and made numerous,
outrageous remarks about the defendant, including that “[h]e shouldn’t be out of his
cell unless he has a leash on”; that “I wish [the victim] had [] a shotgun in his
hand . . . and [had] blown [the defendant’s] face off”; that “I wish that I could see
him sitting here with no face, blown away by a shotgun”; that “I wish he had used
[the gun] on himself”; and that “I wish he had been killed in the accident.” 477 U.S.
at 179–81 & nn.9–12. The Court weighed these “undoubtedly [] improper”
statements against the “heavy” evidence of guilt and the trial court’s admonitions
that the “arguments of counsel were not evidence.” Id. at 180, 182. It also
considered that the prosecutor did not “manipulate or misstate the evidence,” nor did
his remarks “implicate other specific rights” like the right to counsel. Id. at 182.
And it concluded that while the defendant’s “trial was not perfect—few are,”
“neither was it fundamentally unfair.” Id. at 183.
In support of his Darden claim, Severson challenges much of the same
prosecutorial conduct that he invokes in support of his Strickland claim (though not
the expert-vouching comment). He adds that the prosecutor inflamed the jury’s
9 23-3187 & 23-3247
passions by stating that “Mary . . . speaks to us from her grave as to who killed her
and why she died,” and that the prosecutor violated his right to remain silent under
Griffin v. California, 380 U.S. 609 (1965), by stating that “[n]obody knows, that has
testified, what happened between [Mary and Severson].” The Idaho Supreme Court
concluded that none of these comments rose to the level of prosecutorial misconduct,
and that the alleged Griffin violation was too “ambiguous” and “isolated” to deprive
Severson of a fair trial. Severson I, 215 P.3d at 439–40. Concluding that Severson
failed to show at least two improper statements, the Severson I court did not analyze
the statements’ cumulative impact on the verdict. See id. at 443. Assuming without
deciding that all the misconduct alleged is actionable, and thus analyzing the
potential cumulative prejudice issue de novo, Pirtle, 313 F.3d at 1167,4 we see no
“reasonable probability” that the prosecutor’s actions “rendered the trial
fundamentally unfair.” Ford, 999 F.3d at 1225 (quoting Deck, 814 F.3d at 985).
The extensive and outrageous misconduct held insufficient in Darden is
considerably worse than the prosecutor’s comments here. See 477 U.S. at 179–81
& nn.9–12. Given the strength of the evidence against Severson and the trial court’s
jury instructions, the prosecutor’s remarks have not shaken our “confidence” in the
jury’s guilty verdict. Kyles, 514 U.S. at 434; see also Michaels v. Davis, 51 F.4th
4
As with Severson’s Strickland claim, we assume for the sake of argument
that the “cumulative error” doctrine is “clearly established” for Darden claims.
10 23-3187 & 23-3247
904, 952–54 (9th Cir. 2022) (rejecting Darden claim where prosecutor accused
defendant of “devil worship,” called him “evil” and a “beast,” “monster,”
“psychopath,” “professional” and “contract killer,” and asked jurors to step into the
victim’s shoes). This conclusion holds firm even acknowledging that the evidence
of guilt in Darden was stronger than it is here, and that the jury in this case
deliberated for two days before returning a verdict. This conclusion likewise holds
firm despite Severson’s allegation that the prosecutor violated his rights under
Griffin—a point of distinction between this case and Darden. See Hovey v. Avers,
458 F.3d 892, 912 (9th Cir. 2006) (holding “isolated” Griffin violation harmless
where “minimal in comparison” with evidence of guilt). Even so, given the
voluminous evidence of Severson’s guilt, we cannot say that the prosecutor’s
handful of inappropriate remarks, buried in 166 pages of closing arguments, “so
infected” the 17-day trial “with unfairness” as to deny Severson due process.
Darden, 477 U.S. at 181 (quoting Donnelly v. DeChristoforo, 416 U.S. 637, 643
(1974)).

The magistrate judge’s order denying Severson’s petition for a writ of habeas
