DANIEL STOFFA, Appellant
v.
MICHAEL ZAKEN, Superintendent SCI Greene; DISTRICT ATTORNEY OF FAYETTE COUNTY; ATTORNEY GENERAL OF THE STATE OF PENNSYLVANIA ____________
On Appeal from the United States District Court for the Western District of Pennsylvania (District Court No. 2:22-cv-00621) Magistrate Judge: Honorable Patricia L. Dodge ____________
Submitted Pursuant to Third Circuit L.A.R. 34.1(a) May 20, 2025 ____________
Before: PHIPPS, CHUNG, and ROTH, Circuit Judges
(Filed: July 30, 2025) ____________
OPINION* ____________
CHUNG, Circuit Judge.
* This disposition is not an opinion of the full Court and pursuant to I.O.P. 5.7 does not constitute binding precedent. Daniel Stoffa appeals the District Court’s1 denial of his habeas petition. Stoffa
cannot overcome the deferential standard set forth in the Antiterrorism and Effective
Death Penalty Act of 1996 (“AEDPA”), which allows relief only when a state court’s
decision is “contrary to, or involved an unreasonable application of, clearly established
Federal law, as determined by the Supreme Court of the United States.” 28 U.S.C.
§ 2254(d)(1). We will therefore affirm the District Court.
I. BACKGROUND2
Daniel Stoffa was convicted by a jury in 2018 of multiple counts of rape, indecent
assault, aggravated indecent assault, and involuntary deviate sexual intercourse for
repeatedly raping three sisters, ranging in age from six to sixteen at the time of the
crimes. He was sentenced to 20–40 years’ imprisonment. Stoffa appealed, and the
Superior Court of Pennsylvania affirmed the judgment. Stoffa did not seek review by the
Pennsylvania Supreme Court. In May 2019, Stoffa filed a petition under the
Pennsylvania Post Conviction Relief Act (“PCRA”), raising several claims including the
ineffective assistance of counsel (“IAC”) claim he raises now: that his trial counsel was
ineffective because he should have removed a biased juror, Juror 400, for cause.
During voir dire, the trial court asked prospective jurors, “[i]s there anything about
the nature of this case or the crime itself, which would [cause] you to be biased in your
deliberations against the defendant?” and several prospective jurors, including Juror 400,
1 The term “District Court” in this opinion refers to the Magistrate Judge, who presided over this matter with the consent of the parties. 2 Because we write for the parties, we recite only the facts pertinent to our decision. 2 raised their hands. Appx. 50. When asked, “[D]o you believe that you would be unable
to serve as a fair and impartial juror?”, Juror 400 answered, “[p]robably.” Id. at 52. Juror
400 also answered affirmatively when asked if he or a member of his household was
“involved with any child advocacy group,” and raised his hand when the jurors who
answered affirmatively were asked if their involvement with children would make them
unable to serve fairly and impartially as a juror. Id. at 53–54. Stoffa’s counsel did not
move to strike Juror 400 for cause.
At the PCRA hearing, counsel explained that he thought Juror 400 falsely stated
that he could not be fair because Juror 400 wanted to get out of jury duty. Stoffa’s
counsel further explained that the defense strategy was that the children were lying and
that he told Stoffa that Juror 400 would be good for the defense because Juror 400 was a
teacher and judged children daily. The PCRA Court denied Stoffa’s petition, and the
Superior Court affirmed. In April 2022, Stoffa filed a petition for a writ of habeas corpus
in the Western District of Pennsylvania, arguing that his trial counsel was ineffective for
failing to strike Juror 400 after he said he could not be fair and impartial. We issued a
certificate of appealability and this appeal followed.
3 II. DISCUSSION3
To obtain habeas relief on his IAC claim, Stoffa must demonstrate that he can
overcome AEDPA’s highly deferential standard of review.4 Specifically, Stoffa must
show that the Superior Court’s decision “was contrary to, or involved an unreasonable
application of, clearly established Federal law, as determined by the Supreme Court of
the United States.” 28 U.S.C. 2254(d)(1). Strickland v. Washington sets forth the
“clearly established Federal law” regarding ineffective assistance of counsel. 466 U.S.
668 (1984). Under Strickland’s two-pronged test, a defendant must first show that trial
counsel was deficient and, if so, that the deficient performance prejudiced the defendant.
Id. at 687. At the first prong, trial counsel’s strategic decisions “made after thorough
investigation of law and facts … are virtually unchallengeable[.]” Id. at 690. At the
second prong, prejudice is shown if “there is a reasonable probability that, but for
counsel’s unprofessional errors, the result of the proceeding would have been different.”
Id. at 694.
3 The District Court had jurisdiction over the petition for a writ of habeas corpus under 28 U.S.C. § 2254. We have jurisdiction over this appeal under 28 U.S.C. §§ 1291 and 2253. We review the District Court’s decision de novo “because no evidentiary hearing was held.” Eley v. Erickson, 712 F.3d 837, 845 (3d Cir. 2013). 4 When “considering a § 2254 petition, we review the ‘last reasoned decision’ of the state courts on the petitioner’s claims.” Simmons v. Beard, 590 F.3d 223, 231–32 (3d Cir. 2009) (quoting Bond v. Beard, 539 F.3d 256, 289–90 (3d Cir. 2008)). In this case, that would be the Superior Court’s decision. We review the Superior Court’s decision under a “highly deferential standard … which demands that state-court decisions be given the benefit of the doubt.” Eley, 712 F.3d at 845 (internal quotations omitted).
4 The Superior Court resolved Stoffa’s claim by focusing on the second Strickland
prong and found that Stoffa failed to establish prejudice. It found that, even if Juror 400
were removed and replaced with an unbiased juror, there was no reasonable probability
that his trial’s outcome would have been different due to the overwhelming evidence
against Stoffa. Stoffa argues that this was error, not because there was a reasonable
probability of a different outcome, but because juror bias is a structural error and as such,
the Superior Court should have presumed he suffered prejudice.5
We read Stoffa’s argument to be that the Superior Court’s finding was “contrary
to” “clearly established law” because it “contradict[ed] [] governing law” that, Price v.
Vincent, 538 U.S. 634, 640 (2003) (internal quotations omitted), upon collateral review
of an ineffectiveness claim, prejudice is presumed for structural errors that lead to
fundamental unfairness at trial, even when there is no reasonable probability that the

3 The District Court had jurisdiction over the petition for a writ of habeas corpus under 28 U.S.C. § 2254. We have jurisdiction over this appeal under 28 U.S.C. §§ 1291 and 2253. We review the District Court’s decision de novo “because no evidentiary hearing was held.” Eley v. Erickson, 712 F.3d 837, 845 (3d Cir. 2013). 4 When “considering a § 2254 petition, we review the ‘last reasoned decision’ of the state courts on the petitioner’s claims.” Simmons v.

We review the Superior Court’s decision under a “highly deferential standard … which demands that state-court decisions be given the benefit of the doubt.” Eley, 712 F.3d at 845 (internal quotations omitted).
4 The Superior Court resolved Stoffa’s claim by focusing on the second Strickland
prong and found that Stoffa failed to establish prejudice. It found that, even if Juror 400
were removed and replaced with an unbiased juror, there was no reasonable probability
that his trial’s outcome would have been different due to the overwhelming evidence
against Stoffa. Stoffa argues that this was error, not because there was a reasonable
probability of a different outcome, but because juror bias is a structural error and as such,
the Superior Court should have presumed he suffered prejudice.5
We read Stoffa’s argument to be that the Superior Court’s finding was “contrary
to” “clearly established law” because it “contradict[ed] [] governing law” that, Price v.
Vincent, 538 U.S. 634, 640 (2003) (internal quotations omitted), upon collateral review
of an ineffectiveness claim, prejudice is presumed for structural errors that lead to
fundamental unfairness at trial, even when there is no reasonable probability that the
outcome of trial would have been different absent the error. In order to prevail on that
argument, Stoffa must first demonstrate that there is clearly established law, i.e., a
Supreme Court holding, that a finding of prejudice upon collateral review of an
5 “[T]he defining feature of a structural error is that it affects the framework within which the trial proceeds, rather than being simply an error in the trial process itself.” Weaver v. Massachusetts, 582 U.S. 286, 295 (2017) (internal quotations omitted). While some errors are considered structural because they lead to “fundamental unfairness,” other errors are considered structural for different reasons (e.g., the error is of a type that its “effects are simply too hard to measure.”) Id. at 295–96. “An error can count as structural even if the error does not lead to fundamental unfairness in every case.” Id. at 296. In making this argument, Stoffa assumes that Juror 400 was biased. We do not decide that issue and proceed on the same assumption.
5 ineffectiveness claim is mandatory when defense counsel fails to object to the seating of a
biased juror. Andrew v. White, 145 S. Ct. 75, 81, 82–83 (2025) (“A legal principle is
clearly established for purposes of AEDPA if it is a holding of [the Supreme] Court,”
including if the legal principle is “indispensable to the decision[.]”). Stoffa must then
demonstrate that the Superior Court’s decision was contrary to, or an unreasonable
application of, that Supreme Court holding. Harrington v. Richter, 562 U.S. 86, 100
(2011).
Stoffa identifies no Supreme Court holding clearly establishing that trial counsel’s
failure to strike a biased juror creates a presumption of prejudice, obviating the need to
establish a reasonable probability of a different outcome – the burden a petitioner must
ordinarily meet to gain relief. Instead, he cites Weaver v. Massachusetts, 582 U.S. 286
(2017), and claims that the Supreme Court has clearly established the more general
proposition that a finding of prejudice is mandatory in all instances where structural error
leads to fundamental unfairness.
This argument was first raised in Stoffa’s appellate reply brief and is accordingly
doubly forfeited, having never been raised before the District Court nor in Stoffa’s
opening brief here. See Del. Nation v. Pennsylvania, 446 F.3d 410, 416 (3d Cir. 2006);
Norris v. Brooks, 794 F.3d 401, 406 (3d Cir. 2015). Even if this argument were not
forfeited, it would fail because Weaver does not stand for the proposition asserted by
Stoffa, much less clearly establish it. The Supreme Court in Weaver did not hold that
habeas “relief [] must be granted if … [a structural error] rendered the trial fundamentally
unfair,” “even if there is no showing of a reasonable probability of a different 6 outcome[.]” Weaver, 580 U.S. at 300. Rather, the Supreme Court assumed that relief
was due under those circumstances for “analytical purposes[.]” Id.; see also id. at 306
(Thomas, J., concurring). Thus, Stoffa cannot rely on Weaver to demonstrate that a
Supreme Court holding clearly established that a finding of prejudice was mandatory in
his case.
While Stoffa also cites a number of circuit court decisions as clearly establishing
Federal law that the seating of a biased juror alone is enough to establish prejudice, see,
e.g., Hughes v. United States, 258 F.3d 453, 463–64 (6th Cir. 2001), the Supreme Court
has “repeatedly emphasized [that] circuit precedent does not constitute ‘clearly
established Federal law’” for AEDPA purposes. Glebe v. Frost, 574 U.S. 21, 24 (2014)
(quoting § 2254(d)(1). Moreover, “Circuit precedent cannot ‘refine or sharpen a general
principle of Supreme Court jurisprudence into a specific legal rule that [the Supreme]
Court has not announced.’” Lopez v. Smith, 574 U.S. 1, 7 (2014) (quoting Marshall v.
Rodgers, 569 U.S. 58, 64 (2013)).
In sum, Stoffa fails to establish that the Superior Court unreasonably applied
clearly established Federal law in determining that Stoffa did not demonstrate Strickland
prejudice and we will affirm the District Court’s dismissal of his petition.6
III. CONCLUSION
For the foregoing reasons, we will affirm the judgment of the District Court.
6 Because we will affirm the District Court’s dismissal based on Strickland’s second prong, we need not consider the first prong issue of deficient performance.
