          ORDER DENYING CERTIFICATE OF APPEALABILITY *


Before KELLY, HARTZ, and HOLMES, Circuit Judges.


      Petitioner-Appellant Gabriel John Sedillo, Sr., a state prisoner, seeks a

certificate of appealability (“COA”) pursuant to 28 U.S.C. § 2253(c)(1)(A) so that

he may challenge the district court’s denial of his petition for a writ of habeas

corpus under 28 U.S.C. § 2254. Exercising jurisdiction under 28 U.S.C. § 1291,

we hold that reasonable jurists could not disagree with the district court’s


      *
              This order is not binding precedent except under the doctrines of law
of the case, res judicata, and collateral estoppel. It may be cited, however, for its
persuasive value consistent with Federal Rule of Appellate Procedure 32.1 and
Tenth Circuit Rule 32.1.

      After examining the appellate record, this three-judge panel determined
unanimously that oral argument would not be of material assistance in the
determination of this appeal. See Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G).
The case is therefore ordered submitted without oral argument.
rejection of Mr. Sedillo’s petition. Accordingly, we deny his application for a

COA and dismiss his appeal.

                                   BACKGROUND

      On May 22, 2003, a New Mexico jury convicted Mr. Sedillo of one count

of murder in the first degree and three counts of evidence tampering. After being

sentenced to life in prison, Mr. Sedillo filed a direct appeal to the New Mexico

Supreme Court, raising numerous grounds of error. Among those grounds, he

alleged that the state district court erred in refusing to strike a juror for cause due

to the fact that she had previously been employed by the prosecutor who

conducted the voir dire at trial. The court denied his averments of error, and

affirmed his conviction and sentence.

      Mr. Sedillo then filed a motion collaterally attacking his conviction in New

Mexico state district court. He raised a number of claims, including various

allegations of ineffective assistance of counsel. The state district court summarily

dismissed his petition, and the New Mexico Supreme Court denied a subsequent

request for a writ of certiorari

      Mr. Sedillo next filed a petition for a writ of habeas corpus in the United

States District Court for the District of New Mexico. On February 12, 2007, the

magistrate judge issued a comprehensive report, recommending that the district

court dismiss Mr. Sedillo’s petition with prejudice. Liberally construing Mr.

Sedillo’s pleadings, the magistrate judge concluded that his federal petition raised

                                          -2-
many of the same claims as his state direct appeal and collateral petition, notably

including Mr. Sedillo’s contention that the state district court erred in refusing to

strike an allegedly biased juror. Importantly, the magistrate judge also construed

Mr. Sedillo’s filing as stating a claim that his counsel failed to properly

investigate a potential alibi witness—Yvette Chacon.

      The magistrate judge originally recommended that the latter alibi claim be

dismissed for lack of detail. However, Mr. Sedillo filed objections to the report

and provided a more detailed contextual basis for the claim. He essentially

alleged that Ms. Chacon’s testimony would have placed him at a different

location at the time that the murder and subsequent cover-up events occurred.

The district court remanded the matter back to the magistrate judge, who

appointed counsel for Mr. Sedillo and held a hearing on the matter.

Subsequently, Mr. Sedillo filed an amended petition, appearing to set forth an

additional claim—viz., that counsel was ineffective for failing to investigate and

secure the testimony of the alibi witness. The district court, on agreement of the

parties, stayed the matter, and held the petition in abeyance, permitting Mr.

Sedillo to return to state district court in order to exhaust this claim.

      After the stay was issued, the state district court considered Mr. Sedillo’s

claim. Following an evidentiary hearing, the court issued factual findings, which

established the following. At trial, the State’s position was that, on the day of the

murder, Mr. Sedillo, Luis Rosales and the victim left Sam Martinez’s Bayard,

                                          -3-
New Mexico, automotive repair shop in a Chevrolet Blazer. The court found that

the trial testimony of Mr. Martinez established that Mr. Sedillo had returned with

the Blazer—and without the victim—“three to four hours later at around 4:30

p.m. to 5:30 p.m.” when it was “still light outside.” R., Vol. I, at 644 (Order Den.

Relief Based on Claim of Ineffective Assistance of Counsel, filed July 31, 2009).

When the vehicle returned, Mr. Martinez testified that he found out the victim had

been murdered by Mr. Sedillo and Mr. Rosales.

      At the evidentiary hearing, Ms. Chacon testified that she and Mr. Sedillo

“talk[ed] . . . for ‘15 maybe 20 minutes’ outside of a residence around 4:00 p.m.

OR 5:00 p.m.” 

(quoting testimony of Yvette Chacon). Ms. Chacon

claimed that she had been drinking alcohol throughout the day, and that the

“residence” to which she referred “‘could have been an auto repair shop.’” 

of Yvette Chacon). Mr. Sedillo argued that her testimony

effectively contradicted the State’s version of the events that day in that it tended

to show that he had never left the shop at times material to the murder.

      The state district court denied Mr. Sedillo’s ineffective assistance of

counsel claim on the ground that failure to call Ms. Chacon to testify was not

objectively unreasonable because she had failed to cooperate after two attempts

by counsel to find out what she knew. Further, the court concluded that Mr.

Sedillo had not shown that counsel’s failure to obtain Ms. Chacon’s testimony,

even if unreasonable, would have changed the result of his trial. On appeal, the

                                         -4-
Supreme Court of New Mexico denied Mr. Sedillo’s petition for a writ of

certiorari.

       Upon Mr. Sedillo’s return to federal court, the magistrate judge issued a

new report on the alibi claim, finding first that Mr. Sedillo could not rebut the

state district court’s factual findings by clear and convincing evidence. He then

recommended that the claim be dismissed because Mr. Sedillo could not “show

that trial counsel knew anything about the potential content of Chacon’s

testimony that would make counsel’s failure to subpoena her unreasonable and

that, even if counsel’s performance was objectively unreasonable, Sedillo had not

demonstrated prejudice.” 

(Dist. Ct. Order Adopting Mag. J. Prop.

Findings & Recommended Disposition, filed July 13, 2010). The district court

adopted the magistrate judge’s report and denied a COA. Mr. Sedillo filed a

timely notice of appeal.

                            STANDARD OF REVIEW

       A COA is a jurisdictional prerequisite to our review of a habeas

application. 28 U.S.C. § 2253(c)(1)(A); accord Clark v. Oklahoma, 

, 713 (10th Cir. 2006) (citing Miller-El v. Cockrell, 

, 336

(2003)). “We will issue a COA ‘only if the applicant has made a substantial

showing of the denial of a constitutional right.’” Allen v. Zavaras, 

, 1199 (10th Cir. 2009) (quoting 28 U.S.C. § 2253(c)(2)). To satisfy this

standard, “an applicant must demonstrate ‘that reasonable jurists could debate

                                         -5-
whether . . . the petition should have been resolved in a different manner or that

the issues presented were adequate to deserve encouragement to proceed

further.’” 

v. McDaniel, 

, 484 (2000)). “[F]ull

consideration of the factual or legal bases adduced in support of the claims” is not

required. 

. Rather, our inquiry on habeas review

requires “an overview of the claims . . . and a general assessment of their merits.”

and Effective Death Penalty Act of 1996 (“AEDPA”)

further limits our review of federal habeas claims adjudicated on the merits in

state-court proceedings. See 28 U.S.C. § 2254(d)(1)–(2). The New Mexico state

courts addressed Mr. Sedillo’s claims on the merits. Consequently, he is entitled

to federal habeas relief only if he can show that the state courts’ adjudication

either “resulted in a decision that was contrary to, or . . . an unreasonable

application of, clearly established Federal law, as determined by the Supreme

Court[,] . . . or . . . resulted in a decision that was based on an unreasonable

determination of the facts in light of the evidence presented in the State court

proceeding.” 

review the district court’s legal analysis of the state-court

decision de novo, Welch v. Workman, 

, 991 (10th Cir. 2011), our

COA inquiry will incorporate AEDPA’s deferential treatment of that decision, see

Dockins v. Hines, 

, 938 (10th Cir. 2004); see also Charlton v.

                                          -6-
Franklin, 

, 1115 (10th Cir. 2007). Thus, in order for Mr. Sedillo to

obtain a COA, he must show that reasonable jurists could debate the district

court’s determination that he was not entitled to relief in light of the standards

embodied in AEDPA. See 

.

                                   DISCUSSION

       Mr. Sedillo requests a COA on two issues. First, he contends that

reasonable jurists could debate the correctness of the district court’s rejection of

his claim that his counsel was ineffective for failing to adduce and secure the

testimony of Ms. Chacon (i.e., the purported alibi witness) at trial. Second, he

claims that the district court applied the wrong legal standard in deferring to the

New Mexico Supreme Court’s determination regarding the alleged partiality and

bias of a juror at trial.

A.     Ineffective Assistance of Counsel

       Because Mr. Sedillo’s first claim rests on an allegation of ineffective

assistance of counsel, we apply the framework articulated in Strickland v.

Washington, 

(1984). “Under Strickland, [a petitioner] must show

that counsel’s performance fell below an objective standard of reasonableness as

measured against prevailing professional norms, and he must show that there is a

reasonable probability that the outcome would have been different but for

counsel’s inadequate performance.” Sandoval v. Ulibarri, 

, 909

(10th Cir. 2008) (citing 

). “Surmounting Strickland’s

                                          -7-
high bar is never an easy task,” Harrington v. Richter, 

, 788 (2011)

(quoting Padilla v. Kentucky, 

, 1485 (2010)) (internal quotation

marks omitted), and “[e]stablishing that a state court’s application of Strickland

was unreasonable under § 2254(d) is all the more difficult” in light of AEDPA’s

highly deferential standard of review, 

      In applying the principles in Strickland, “[c]ourts may address the

performance and prejudice components in any order and need not address both if

a [petitioner] fails to make a sufficient showing of one.” Cannon v. Gibson, 

, 1273 (10th Cir. 2001) (second alteration in original) (quoting Hale v.

Gibson, 

, 1314 (10th Cir. 2000)) (internal quotation marks omitted).

Here, we elect to resolve Mr. Sedillo’s request for a COA by addressing the

performance prong of Strickland.

      Mr. Sedillo challenges the district court’s denial of his claim that his

attorney was ineffective for failing to subpoena Ms. Chacon, allegedly a potential

alibi witness. In resolving this claim, the magistrate judge found, and the district

court agreed, that Mr. Sedillo had not rebutted the presumption of correctness that

attached to the state district court’s factual findings. The district court further

concluded that Mr. Sedillo “ha[d] not offered any evidence to suggest that his

counsel knew the importance of Chacon’s testimony[,] . . . [and w]ithout knowing

what [she] might say on the witness stand, and without any evidence from Sedillo

regarding what he thought [she] might say on the witness stand, defense counsel’s

                                          -8-
failure to subpoena her simply cannot be considered unreasonable.” R., Vol. I, at

764.

       On appeal, Mr. Sedillo claims that the district court’s conclusion is flawed

for essentially three reasons. First, he contends that he has sworn that Ms.

Chacon could have been an alibi witness twice in his verified pleadings. Second,

he suggests that he conveyed to his counsel the probative value of her testimony.

As proof, he points to an e-mail sent by defense investigator Carlos Herrera to his

counsel, which states: “We spoke briefly about his ‘alibi’ and how to prove it.

[Mr. Sedillo] stated that the only people who could say he was at the shop that

afternoon are Peter [Alcorta] and Yvette [Chacon].” 

(E-mail from

Carlos Herrera to Devon M. Fooks and Jeffrey Buckels, dated Apr. 4, 2003).

Finally, he claims that his attorneys did, in fact, unsuccessfully send investigators

to talk to Ms. Chacon on two separate occasions. Because it is uncontested that

Ms. Chacon was not an eyewitness to the murder itself, Mr. Sedillo concludes that

the only reason his counsel would have had any interest in her testimony would

have been for purposes of an alibi.

       As a general matter, the allegations in Mr. Sedillo’s habeas filings offer

little evidence as to what counsel knew before or during trial. At the most, they

represent Mr. Sedillo’s own legal theory and assessment of the probative value of

Ms. Chacon’s testimony. Thus, they cannot serve as cogent evidence of counsel’s

knowledge of the content of that testimony.

                                         -9-
       Additionally, Investigator Herrera’s e-mail was part of a set of notes that

Mr. Sedillo did not introduce at the state evidentiary hearing. Our “review under

§ 2254(d)(1) is limited to the record that was before the state court that

adjudicated the claim on the merits.” Cullen v. Pinholster, 

, 1398

(2011). Mr. Sedillo does not directly challenge the magistrate judge’s account of

the state district court’s finding that “[these] notes were not offered into evidence

and were not made part of the record at the evidentiary hearing.” R., Vol. I, at

738 n.4 (Mag. J. Second Prop. Findings & Recommended Disposition, filed Apr.

28, 2010). Thus, we do not consider this evidence on appeal. 1

      Further, that counsel unsuccessfully tried to contact Ms. Chacon to see

what she knew does not establish knowledge of the contents of her potential

testimony. Counsel was ostensibly conducting a thorough investigation of all

potential witnesses. At the evidentiary hearing, Ms. Chacon testified that she


      1
              Furthermore, the magistrate judge also properly reasoned that, even
assuming that the investigator’s notes could be considered, their probative value
is far from dispositive. Mr. Sedillo does not now challenge counsel’s failure to
investigate Ms. Chacon’s testimony—only counsel’s failure to secure her
testimony by subpoena. It was the State’s position that Mr. Sedillo was in fact at
Mr. Martinez’s shop on the day of the murder, but left and returned after he
committed the crime and tried to eliminate any evidence of it. Thus, a mere
hollow statement that “the only people who could say [Mr. Sedillo] was at the
shop that afternoon are Peter [Alcorta] and Yvette [Chacon]” does not imply that
Ms. Chacon would testify that he never left the shop. R., Vol. I, at 278. Even
affording Mr. Sedillo the most favorable inference arising from these notes, they
establish at the most that Mr. Sedillo considered Ms. Chacon a potential alibi
witness. They fail to reflect “the [potential] content of her testimony such as
when [she] saw him at the shop, for how long, or for what reason.” 

n.4.

                                        -10-
refused to answer counsel’s inquiries because “she did not know anything,” 

but that she nonetheless “would have come forward if she knew she could

have helped the Defendant,” 

Again, nothing here suggests that counsel

understood or knew the facts underlying Ms. Chacon’s potential testimony.

Indeed, if counsel had elected to subpoena Ms. Chacon without knowledge of the

content of her potential testimony—given her lack of cooperation and

resistance—one conceivably could have asserted that counsel was acting

imprudently because he had no way of knowing whether or not her testimony

would backfire on Mr. Sedillo.

      The state district court found that it was not “objectively unreasonable for

[Mr. Sedillo’s] attorney not to subpoena or call Yvette Chacon[,] . . . considering

her lack of cooperation and counsel’s inability after two efforts . . . to find out

what she knew.” 

The district court agreed, finding that the state

court’s rejection of Mr. Sedillo’s ineffective assistance of counsel claim was

neither contrary to, nor an unreasonable application of, Strickland, and was not an

unreasonable determination of the facts in light of the evidence presented.

      We discern no error in this conclusion. Reasonable jurists could not debate

the district court’s resolution of this claim. Counsel cannot be faulted for failing

to subpoena a potential alibi witness when, despite diligent investigation, the

content of that witness’s testimony was not evident. Consequently, Mr. Sedillo is

not entitled to a COA on his ineffective assistance of counsel claim.

                                          -11-
B.    Juror Disqualification

      Mr. Sedillo also requests a COA on the issue of whether the New Mexico

Supreme Court’s resolution of his juror-bias claim—that is, its failure to require

the removal of a juror for cause—violated his constitutional rights. 2 This claim

implicates Mr. Sedillo’s rights under the Sixth and Fourteenth Amendments. See,

e.g., Goss v. Nelson, 

, 627 (10th Cir. 2006). The New Mexico

Supreme Court rejected his argument on appeal:

             [Mr. Sedillo] argues . . . that the district court erred in refusing
             to strike juror Sally Johnston for cause, because she was
             previously employed by the prosecutor while he was in private
             practice. The record reveals that the prosecutor who conducted
             voir dire, Jim Foy, was substituting for the prosecutor who
             actually tried the case. Johnston explained that she was
             employed by Foy for two years, and during that time she worked
             on only one case. Though she conceded that they worked
             together “pretty closely,” she assured the court that she could be
             fair and impartial, even if the question of guilt was close, and
             that she would look at all of the facts before making a decision.
             In light of these answers and the fact that Foy did not continue to
             prosecute the case, we conclude the district court did not abuse
             its discretion in denying the challenge for cause.

R., Vol. I, at 51 (N.M. Supreme Ct. Decision, filed Jul. 14, 2005). The magistrate



      2
             We operate on the assumption that Mr. Sedillo exhausted his juror-
bias claim. In its response to Mr. Sedillo’s federal habeas petition, the State
expressly conceded that the juror-bias claim that Mr. Sedillo presented “to the
highest state court . . . ha[d] been exhausted.” R., Vol. I, at 65 (Br. in Supp. of
Resp’t’s Mot. to Dismiss, filed Aug. 25, 2006); see 28 U.S.C. § 2254(b)(3) (“A
State shall not be deemed to have waived the exhaustion requirement or be
estopped from reliance upon the requirement unless the State, through counsel,
expressly waives the requirement.”).

                                         -12-
judge found, and the district court agreed, that Mr. Sedillo had failed to “rebut the

presumption of correctness given to the trial court’s impartiality determination”

and to show that the New Mexico Supreme Court’s decision was contrary to, or

an unreasonable application of, federal law. 

      Before us, Mr. Sedillo appears to be attacking the district court’s

conclusion on the grounds that it applied the wrong legal standard when assessing

the reasonableness of the New Mexico Supreme Court’s decision. Specifically,

he argues that both the New Mexico Supreme Court and the federal district court

“ignored altogether federal jurisprudence with respect to the ‘implied bias’

doctrine.” Aplt. Opening Br. at 20.

      The bias of a prospective juror may be actual or implied; that is, it may be

bias in fact or bias conclusively presumed as matter of law. United States v.

Wood, 

, 133 (1936). As we have discussed this doctrine, it involves

an objective legal inquiry that “turns on an . . . evaluation of the challenged

juror’s experiences and their relation to the case being tried.” Gonzales v.

Thomas, 

, 987 (10th Cir. 1996). Unlike actual bias—which presents a

factual question—“[w]hether implied bias exists in a juror is a legal

determination.” 

be established, for example, where “the juror is an

actual employee of the prosecuting agency, . . . a close relative of one of the

participants in the trial or . . . a witness or somehow involved in the criminal

transaction.” 

v. Phillips, 

, 222 (1982) (O’Connor,

                                         -13-
J., concurring)) (internal quotation marks omitted). “A finding of implied bias is

appropriate when the juror, although she believes that she can be impartial, is so

closely connected to the circumstances at issue in the trial that bias is presumed.”

United States v. Cerrato-Reyes, 

, 1261 (10th Cir. 1999), abrogated

in part on other grounds as stated in United States v. Jones, 

, 709

(10th Cir. 2006).

      We are disinclined, however, to reach Mr. Sedillo’s implied-bias

contention. Neither Mr. Sedillo’s pro se habeas petition nor his pro se amended

habeas petition—construed with maximum liberality—revealed that his juror-bias

claim was predicated on a theory of implied bias. Theories or claims not raised in

a habeas petition are ordinarily deemed waived. See Parker v. Scott, 

, 1327 (10th Cir. 2005) (“Parker raises several other alleged failures of

counsel to object at trial, all of which he has waived by failing to assert them in

his district court habeas petition.”); Jones v. Gibson, 

, 958 (10th Cir.

2000) (where the “[p]etitioner did not make [an] argument in his revised habeas

petition[,] . . . this court need not consider it”); see also Thompkins v. McKune,

No. 11-3022, 

, at *5 (10th Cir. Aug. 12, 2011) (unpublished)

(“[Petitioner] waived this argument by failing to assert it in his federal habeas

petition.”). And Mr. Sedillo has offered us no reason to deviate from our usual

practice regarding waiver.

      In light of this omission, it is not surprising that the magistrate judge

                                         -14-
clearly did not interpret Mr. Sedillo as putting forward a theory of implied bias.

Instead, it construed his argument as one based on alleged actual bias and

proceeded to determine whether the New Mexico Supreme Court’s failure to

require the removal of the juror for cause because she was actually biased was

contrary to, or an unreasonable application of, clearly established federal law. In

his objections to the magistrate judge’s report, Mr. Sedillo did hint at the

possibility that his juror-bias claim extended beyond a theory of actual bias. He

stated that “[t]here [was] a probability of ‘presumption of prejudice’” in Ms.

Johnston’s ability to serve as a juror because she “would feel obligated to [the]

prosecution attorneys.” R., Vol. I, at 222 (Pet’r’s Objs. to Mag. J. Prop. Findings

& Recommended Disposition, filed Apr. 5, 2007). Conceivably, this statement

could be construed as advancing an argument of implied bias—viz., a contention

that, despite Ms. Johnston’s assertions to the contrary, she was objectively unable

to serve as a juror as a matter of law in light of her prior relationship with the

prosecutor conducting voir dire. However, even if this were so, such a contention

would have come too late. Arguments advanced for the first time in an objection

to a magistrate judge’s report are waived. See United States v. Garfinkle, 

, 1031 (10th Cir. 2001) (“In this circuit, theories raised for the first time

in objections to the magistrate judge’s report are deemed waived.”); see also San

Roman v. Vaughn, No. 11–6103, 

, at *4 n.5 (10th Cir. Sept. 30,

2011) (unpublished) (finding an argument waived where the petitioner did not

                                          -15-
raise it until filing objections to the magistrate judge’s report recommending

dismissal of his petition).

      Moreover, as the district court noted, Mr. Sedillo “cite[d] no law to support

this standard,” R., Vol. I, at 751, of a presumption of prejudice. In other words,

Mr. Sedillo cited no legal authority that would have alerted the district court to

any purported theory of implied bias. Thus, quite reasonably, the district

court—like the magistrate judge—construed the gravamen of Mr. Sedillo’s juror-

bias claim to be a contention of actual bias—that is, a contention that the New

Mexico Supreme Court erred in failing to conclude that the juror (Ms. Johnston)

was actually biased by virtue of her relationship with the prosecutor who did the

voir dire. Under this view of Mr. Sedillo’s argument, the district court concluded

that the magistrate judge was correct in finding that Mr. Sedillo’s juror-bias claim

was without merit because the New Mexico Supreme Court’s decision was not

contrary to, or an unreasonable application of, clearly established federal law.

Because of Mr. Sedillo’s repeated waivers, we are disinclined to reach the merits

of his implied-bias argument.

      Even were we to do so, however, we would conclude that reasonable jurists

could not debate the district court’s resolution of Mr. Sedillo’s juror-bias claim

because the New Mexico Supreme Court’s decision was neither contrary to nor an

unreasonable application of clearly established federal law. 3 As an initial matter,

we are called upon to determine whether a juror-bias argument grounded upon an

implied-bias theory in this factual context has a footing in clearly established

federal law. As we have made clear, “[w]hether the law is clearly established is

the threshold question under § 2254(d)(1).” House v. Hatch, 

, 1015

(10th Cir. 2008). Although House casts doubt on the matter, see 

we

are content to assume without deciding that an implied-bias theory does fall

within the ambit of clearly established federal law in this case, 4 see Brooks v.

Dretke, 

, 329 (5th Cir. 2006) (“We maintain that the doctrine of

implied bias is ‘clearly established Federal law as determined by the Supreme


      3
              Mr. Sedillo has not suggested that the New Mexico Supreme Court
failed to adjudicate his juror-bias claim on the merits, nor has he objected to the
district court’s application of the deferential standards of AEDPA. Therefore, we
apply those standards here. We inquire into whether the reasoning or result of the
New Mexico Supreme Court’s decision contradicts clearly established Supreme
Court law. See Early v. Packer, 

, 8 (2002) (noting that “[a]voiding
these pitfalls [i.e., the grounds for error under the “contrary to” portion of §
2254(d)(1)] does not require citation of our cases—indeed, it does not even
require awareness of our cases, so long as neither the reasoning nor the result of
the state-court decision contradicts them”); Aycox v. Lytle, 

, 1177
(10th Cir. 1999) (“[W]e owe deference to the state court’s result, even if its
reasoning is not expressly stated.”).
      4
             In support of his arguments, Mr. Sedillo relies primarily on our
decision in Gonzales, where we recognized that a defendant may in some
instances challenge a prospective juror based upon allegations that he or she is
impliedly biased. 

–87. Although Gonzales does rely on Justice
O’Connor’s concurrence in 

(O’Connor, J., concurring),
Mr. Sedillo does not cite to any controlling precedent of the Supreme Court to
support his argument.

Court.’” (quoting 28 U.S.C. § 2254(d)(1))), because that assumption has no

impact on the outcome.

      In short, Mr. Sedillo cannot demonstrate that the New Mexico Supreme

Court’s decision is contrary to, or an unreasonable application of, clearly

established federal law. In making his argument, Mr. Sedillo does not point to

one Supreme Court case that would suggest that the New Mexico Supreme

Court’s resolution of his juror-bias claim was unreasonable, and it is the Supreme

Court’s law that is the focus of our AEDPA inquiry. See 28 U.S.C. § 2254(d)(1)

(noting that the AEDPA inquiry is whether the state court decision was “contrary

to, or involved an unreasonable application of, clearly established Federal law, as

determined by the Supreme Court of the United States” (emphasis added)); see

also Teniente v. Wyo. Attorney Gen., 412 F. App’x 96, 105 (10th Cir. 2011) (“It

should not be forgotten that it is that law [of the Supreme Court]—and not

ours—that defines the boundaries of clearly established federal law for AEDPA

purposes.”).

      To be sure, we may look to the precedent of the lower federal courts in

attempting to discern when a state court’s decision is contrary to, or involves an

unreasonable application of, clearly established federal law as defined by the

Supreme Court. See Ouber v. Guarino, 

, 26 (1st Cir. 2002) (“The

AEDPA also requires that the relevant legal rule be clearly established in a

Supreme Court holding, rather than in dictum or in holdings of lower federal

                                        -18-
courts. This does not mean, however, that other federal court decisions are

wholly irrelevant to the reasonableness determination.” (citation omitted));

Matteo v. Superintendent, SCI Albion, 

, 890 (3d Cir. 1999) (en banc)

(“[W]e do not believe federal habeas courts are precluded from considering the

decisions of the inferior federal courts when evaluating whether the state court’s

application of the law was reasonable.”); see also Casey v. Moore, 

,

907 (9th Cir. 2004) (“Although lower federal court and state court precedent may

be relevant when that precedent illuminates the application of clearly established

federal law as determined by the United States Supreme Court, if it does not do

so, it is of no moment.”); cf. Teniente, 412 F. App’x at 105 (assessing the “debate

among reasonable jurists of the federal courts” regarding the content of clearly

established Supreme Court law, in attempting to resolve an AEDPA inquiry). In

this regard, we note that Mr. Sedillo is not prohibited from relying, as he does, on

our implied-bias precedent. But that reliance in unavailing.

      In particular, Mr. Sedillo cites the portion of Gonzales that draws upon

Justice O’Connor’s concurrence in 

. See 

.

That concurrence suggests that implied bias may be established where, for

example, “the juror is an actual employee of the prosecuting agency . . . or

somehow involved in the criminal transaction.” 

(O’Connor, J., concurring). Guided by the concurrence, however, we emphasized

in Gonzales that “[t]he implied bias doctrine should not be invoked lightly.” 99

F.3d at 987. It “must be reserved for those ‘extreme’ and ‘exceptional’

justice.’” 

original) (quoting 

(O’Connor, J., concurring)).

      Mr. Sedillo has not identified a case decided by a lower federal court that

has found implied bias on facts such as these. More specifically, Mr. Sedillo has

not identified any precedent of the lower federal courts that directly supports his

contention (or even indirectly supports it by analogy) that the New Mexico

Supreme Court’s decision is contrary to or an unreasonable application of clearly

established Supreme Court law. And our reading of lower-court precedent does

not avail Mr. Sedillo. For example, it is notable under the facts here that Ms.

Johnston worked with Mr. Foy “while he was in private practice,” not during the

time she served on the jury. R., Vol. I, at 51. In other words, she was not an

“actual employee of the prosecuting agency.” 

(O’Connor, J., concurring). Under our precedent, it is far from clear that a

prospective juror’s prior working relationship with a prosecutor who does not

actually try the case, standing alone, would be enough to satisfy the demanding

showing for implied bias. See 

–91 (declining to presume

as a matter of law that a juror in a rape trial is impliedly biased merely because

she was herself the victim of a different rape); cf. Burton v. Johnson, 948 F.2d

                                         -20-
1150, 1159 (10th Cir. 1991) (presuming bias in a case where the defense was

battered-wife syndrome and the challenged juror suffered from similar “abuse,

both mental and physical, [which] continued over a long period of time”). In

other words, it is far from clear that the “average person in the position of [Ms.

Johnston] . . . would be prejudiced,” 

–61 (quoting

United States v. Torres, 

, 45 (2d Cir. 1997)) (internal quotation marks

omitted), or that she had “such a close connection to the circumstances at hand

that bias must be presumed.” 

(quoting United States v.

Scott, 

, 699 (5th Cir. 1988)) (internal quotation marks omitted).

Moreover, case law from other circuits is similarly unhelpful for Mr. Sedillo. See

Ray v. Johnson, 

, No. 98-10659, 

, at *1 (5th Cir.

Sept. 20, 1999) (per curiam) (unpublished table case) (stating that a “friendship

with the victim, even a close friendship, is not sufficient to imply bias to a

juror”); Treesh v. Bagley, 

, 437 (6th Cir. 2010) (finding no

ineffective assistance of counsel for failing to strike a juror for cause where the

juror previously was in a course taught by the prosecutor because the record did

not demonstrate implied bias); see also 

(collecting cases from “[o]ther circuits” that “have refused to find implied bias”).

      Mr. Sedillo contends that Mr. Foy “was the elected District Attorney whose

name appear[ed] on the Criminal Information charging Mr. Sedillo with murder.”

Aplt. Opening Br. at 20. But Mr. Sedillo fails to show how this fact is legally

                                         -21-
significant in this case. Mr. Foy did not actually try the case; he only filled in for

another prosecutor during the voir dire. There are no facts suggesting that Ms.

Johnston had any prior knowledge about the issues in the case, or felt any

allegiance to the prosecution. All that the record shows is that she and the

prosecutor who conducted the voir dire had worked together before in another

context, and not while he was employed by the State.

      Consequently, the New Mexico Supreme Court’s decision was not contrary

to, or an unreasonable application of, clearly established federal law, see 28

U.S.C. § 2254(d)(1), and reasonable jurists could not debate the district court’s

resolution of Mr. Sedillo’s juror-bias claim.

                                   CONCLUSION

      For the foregoing reasons, we DENY Mr. Sedillo’s application for a COA

and DISMISS his appeal.
