Chalan Santo Papa, Juan Pablo Dos Assistant Attorneys General Suite 101 Office of the Attorney General Hagåtña, GU 96910 Appellate & Writing Division 134 W.

BEFORE: ROBERT J. TORRES, Chief Justice; F. PHILIP CARBULLIDO, Associate Justice; and KATHERINE A. MARAMAN, Associate Justice.
CARBULLIDO, J.:
[1] Defendant-Appellant Brian Jason Martinez aka Brenda Joyce Martinez appeals a judgment
of conviction stemming from a police chase, crash, and subsequent arrest. Martinez was charged
with theft of an automobile, possession of a Schedule II controlled substance, eluding a police
officer, resisting arrest, disorderly conduct, and reckless driving with property damage. The trial
court granted Martinez’s motion for acquittal on the disorderly conduct charge.
[2] At trial, Martinez’s attorney conceded that the prosecution had his client “dead to rights”
on all the remaining charges, except for theft of an automobile. Transcript (“Tr.”) at 24 (Cont’d
Jury Trial, July 5, 2024). Throughout the trial, Martinez’s attorney conceded guilt on the lesser
charges but implored the jury to acquit on the theft charge. The jury rendered a verdict of not
guilty on the theft of an automobile charge and guilty verdicts on the remaining charges.
[3] Martinez argues that her Sixth Amendment rights were violated under the U.S. Supreme
Court’s landmark McCoy decision, where the Court held that “counsel may not admit her client’s
guilt of a charged crime over the client’s intransigent objection to that admission.” McCoy v.
Louisiana, 584 U.S. 414, 426 (2018) (emphasis added). Martinez argues her rights were violated
because “[t]here is no indication in the record that Martinez authorized counsel to admit to the
offenses, nor does the record reflect any colloquy or waiver addressing this issue.” Appellant’s
Br. at 6-7 (June 24, 2025). The only claim Martinez raises on appeal is that her Sixth Amendment-
secured autonomy was violated by trial counsel’s concession of guilt (a “McCoy claim”).
[4] Previously, Martinez filed a motion in this court seeking a limited remand to develop the
factual record on her McCoy claim, which we denied. We determined that “[t]o raise a McCoy
claim on direct appeal, the client’s objection to a concession of guilt must appear somewhere in People v. Martinez, 2025 Guam 17, Opinion Page 3 of 24
the record.” Order at 3 (June 4, 2025). We explained: “If the record is silent on whether the client
objected, it will be more prudent to raise an ineffective assistance of counsel claim in a habeas
proceeding based on McCoy.” Id. We instructed that “[i]f Martinez’s objection appears in the
record, a McCoy claim can be raised in the Appellant’s Opening Brief based on what the record
shows. If there is no objection on the record, as implied by Martinez’s motion, the claim should
be made in a collateral proceeding.” Id. at 4. Despite this court’s instructions, the sole issue
Martinez raises on appeal is a McCoy claim, along with a concession that the record is silent on
the issue. In essence, Martinez asks us to revisit our decision. The People request that this appeal
be dismissed for failure to comply with this court’s order.
[5] Because the record is silent on whether trial counsel consulted with Martinez about
conceding guilt or whether Martinez consented to such a concession, we cannot rule on the sole
claim raised on appeal. We affirm without prejudice to Martinez’s right to raise the McCoy issue
in a habeas corpus proceeding, where an adequate factual record may be developed. We also
appoint Attorney Leevin T. Camacho as Martinez’s habeas counsel.1
I. FACTUAL AND PROCEDURAL BACKGROUND
A. Factual Background
1. Police chase an allegedly stolen truck
[6] Justin Santos called 911 reporting that his truck had been stolen by Martinez and that he
was following it through Mangilao. Police responded, and a high-speed chase ensued, with the
truck driving recklessly across the island. Eventually, the driver of the truck abandoned it after
colliding with multiple police cars in front of the Sumay Payless. The driver successfully escaped
on foot into the jungle. None of the officers involved in the chase or present at the crash scene
1 This Opinion supersedes this court’s order resolving Martinez’s appeal and appointing habeas counsel. See generally Order (Nov. 7, 2025). This Opinion does not affect that appointment of counsel. People v. Martinez, 2025 Guam 17, Opinion Page 4 of 24
could positively identify the driver; instead, they provided only general descriptions of the suspect.
Tr. at 134 (Jury Trial Day 1, Feb. 27, 2025 (testifying they could only describe driver as having
“red curly hair”); see also id. at 143 (“I saw a female wearing a brown shirt, dark or black shorts,
with curly long reddish-brown hair.”).
2. Martinez is arrested
[7] The next day, a police officer was driving through Mangilao when the officer saw a person
fitting Martinez’s description. The officer testified the person had scratches on their arms and legs.
The officer talked to the person, who gave a fake name. Dispatch advised the officer that Martinez
had a distinctive tattoo; but the individual refused to allow the officer to search for it. The
individual then shouted, “I don’t have to f**kin’ say shit to you guys,” to which the officer
responded that she was under arrest. Id. at 115. When the individual attempted to run, the officer’s
partner tackled her to the ground. After securing the individual, the police secured her belongings,
including a black purse. The officer testified that he saw a glass pipe in the purse. He ultimately
seized the pipe and a baggie of methamphetamine. After being arrested, the individual was
positively identified as Martinez and transported to the police station. Martinez allegedly admitted
during a custodial interrogation that she was driving the truck the day before. During the
interrogation, Martinez allegedly explained that she received the truck from a third party after
Santos transferred it to that person to satisfy a debt.
B. Procedural History
[8] Martinez was charged with Theft of an Automobile (As a Second Degree Felony), Eluding
a Police Officer (As a Misdemeanor), and Reckless Driving with Property Damage (As a Petty
Misdemeanor) arising from the police chase. Martinez was also charged with Possession of a
Schedule II Controlled Substance (As a Third Degree Felony), Resisting Arrest (As a People v. Martinez, 2025 Guam 17, Opinion Page 5 of 24
Misdemeanor), and Disorderly Conduct (As a Petty Misdemeanor) stemming from the police
encounter the next day.
1. At trial, defense counsel pursues acquittal on theft while admitting guilt on most other charges
[9] During opening statements, Martinez’s counsel conceded guilt on the “lesser” charges:
So stuff doesn’t add up. . . . I’m going to ask you to use your common sense. . . . And we believe that there are some Charges that [Martinez] admits to, but there are Charges that [Martinez] doesn’t admit to, and the government does not have what it takes to bring the jury to a conclusion beyond a reasonable doubt that [Martinez is] guilty. So we will ask you to find [Martinez] not guilty on most of the Charges -- the most serious Charges -- and [Martinez has] already admitted to the lesser Charges.
Tr. at 100-01 (Jury Trial Day 1). Although counsel emphasized that “there’s a lot of things that
don’t add up,” the only discrepancies he raised related to felony theft. Id. at 99-100. He did not
address the felony drug possession charge in his opening statement.
[10] When cross-examining prosecution witnesses, defense counsel highlighted Martinez’s
admission during custodial interrogation that she was driving the truck. Defense counsel also
elicited that Martinez admitted to being high while driving the truck. However, defense counsel
also elicited that Martinez apologized for crashing into the police vehicle, that the brakes in the
truck did not work, and that Martinez did not admit to owning the seized drugs and paraphernalia.
Defense counsel also attacked the details Santos gave to police when he reported that Martinez
stole the truck. On cross-examination, counsel got one officer to admit it was “quite possible” that
Santos had “concocted a story” to accuse Martinez. See id. at 179. Defense counsel also
highlighted that the police did not follow up on Martinez’s claim that she received the truck from
a third party.
[11] After the People rested their case, defense counsel moved for a judgment of acquittal on
the charges of disorderly conduct and theft of an automobile. Trial counsel stated he could not People v. Martinez, 2025 Guam 17, Opinion Page 6 of 24
make the same motion in good faith on the reckless driving charge and acknowledged there was
also sufficient evidence of resisting arrest, eluding a police officer, and drug possession. The trial
court ultimately denied the motion on the theft charge but granted it on disorderly conduct.
[12] In closing arguments, defense counsel conceded Martinez’s guilt on all remaining charges
except theft: “So I’m not going to talk in too much detail about the chase, or the reckless driving,
or the resisting arrest. Those are, you know, pretty much a foregone conclusion.” Tr. at 21 (Cont’d
Jury Trial). Defense counsel emphasized that “[t]he reason why we’re here today, folks, is because
of this alleged theft of a motor vehicle.” Id. He also argued that police failed to investigate
Martinez’s claim that the truck had been given as payment for a debt and asserted that Santos lied
when providing Martinez’s name to police. Defense counsel concluded that the reason Martinez
did not stop the truck was not that it was stolen, but because Martinez “was high” and “probably
had drugs.” Id. at 24.
[13] The jury returned verdicts of not guilty on the theft of an automobile charge and guilty on
the remaining charges. Martinez received a sentence of three years for possession and the
maximum sentence of one year for the two misdemeanor charges of eluding an officer and resisting
arrest—both to run consecutively—for a total of five years.2 Upon successful completion of the
Residential Substance Abuse Treatment Program, two years of the sentence could be suspended.
Additionally, a $3,000 fine was imposed, payable into the drug treatment fund.
C. Proceedings on Appeal: This Court Denies Limited Remand
[14] Martinez timely appealed. Martinez moved this court for limited remand, asking to
develop the factual record on a potential McCoy claim for concession of guilt without consent. We
denied the motion, determining that “[t]o raise a McCoy claim on direct appeal, the client’s
2 The trial court imposed no sentence for reckless driving with property damage as a petty misdemeanor. People v. Martinez, 2025 Guam 17, Opinion Page 7 of 24
objection to a concession of guilt must appear somewhere in the record.” Order at 3 (June 4, 2025).
We explained that “[i]f the record is silent on whether the client objected, it will be more prudent
to raise an ineffective assistance of counsel claim in a habeas proceeding based on McCoy.” Id.
We instructed that “[i]f Martinez’s objection appears in the record, a McCoy claim can be raised
in the Appellant’s Opening Brief based on what the record shows. If there is no objection on the
record, as implied by Martinez’s motion, the claim should be made in a collateral proceeding.” Id.
at 4.
II. JURISDICTION
[15] This court has jurisdiction over a criminal appeal from a final judgment of conviction. 48
U.S.C.A. § 1424-1(a)(2) (Westlaw through Pub. L. 119-59 (2025)); 7 GCA §§ 3107, 3108(a)
(2005); 8 GCA §§ 130.10, 130.15(a) (2005).
III. STANDARD OF REVIEW
[16] “An alleged violation of the Sixth Amendment that has been preserved below is reviewed
de novo.” People v. Mendiola, 2023 Guam 12 ¶ 17.
IV. ANALYSIS
A. Martinez Makes No Showing Why This Court Should Revisit Its Decision Declining to Hear a McCoy Claim on Direct Appeal When the Record Is Silent
[17] Despite this court’s order, the sole issue Martinez raises on appeal is a McCoy claim, along
with a concession that the record is silent on the issue. Martinez essentially asks this court to
revisit its decision, but her arguments are inadequately supported by authority. See Guam R. App.
P. 13(a)(9)(A). Some pre-McCoy state supreme court decisions have permitted review of this type
of claim on direct appeal following a limited remand, but those cases did so in the context of
ineffective assistance of counsel. Martinez does not engage with this body of persuasive authority
and explicitly states that “[t]his case does not involve a claim of ineffective assistance of counsel People v. Martinez, 2025 Guam 17, Opinion Page 8 of 24
. . . .” Appellant’s Br. at 12. Martinez appears content to “announce a position” and leave it to
this court to “discover and rationalize the basis for [her] claims . . . and then search for authority
either to sustain or reject [her] position.” See Lamb v. Hoffman, 2008 Guam 2 ¶ 35 (quoting Wilson
v. Taylor, 577 N.W.2d 100, 105 (Mich. 1998)).
[18] There may be policy arguments for why this court should revisit its stated preference that
Sixth Amendment claims be brought in habeas proceedings if they require factual development
outside the trial record.3 But Martinez has not made a compelling case here. Based on the
procedural posture of this case, we conclude the most prudent course is to clarify the appropriate
standards, appoint habeas counsel, and instruct Martinez to seek collateral relief consistent with
our prior order.
1. McCoy and the Sixth Amendment right to maintain innocence
a. McCoy announced a new rule of constitutional law based on a defendant’s Sixth Amendment right to autonomy
[19] McCoy is a landmark decision of the U.S. Supreme Court, where the Court held that the
Sixth Amendment guarantees a defendant the right to “insist that counsel refrain from admitting
guilt, even when counsel’s experienced-based view is that confessing guilt offers the defendant
the best chance to avoid the death penalty.” McCoy, 584 U.S. at 417. The Court agreed with the
majority of state courts which had concluded that “counsel may not admit her client’s guilt of a
3 We have broad discretion to order a limited remand “as may be just under the circumstances.” 8 GCA § 130.60 (2005). Because section 130.60 is based on California law, id., NOTE, we find California caselaw persuasive. The scope of our authority “includes the authority to order a limited remand ‘to allow the trial court to resolve one or more factual issues affecting the validity of the judgment but distinct from the issues submitted to the jury, or for the exercise of any discretion that is vested by law in the trial court.’” See People v. Wilson, 552 P.3d 974, 1025 (Cal. 2024) (quoting People v. Braxton, 101 P.3d 994, 1005 (Cal. 2004)). “[T]ypically when a court orders a remand— limited or otherwise—it does so to permit further proceedings concerning an issue raised on appeal, as part of its resolution of that appeal.” Id. We reaffirm that we can order a limited remand in an appropriate case. Nothing in section 130.60’s broad grant of authority for remand “as may be just under the circumstances” forecloses our ability to order a limited remand to develop the record on a Sixth Amendment claim. See 8 GCA § 130.60. However, we are not persuaded that this case warrants departure from our usual preference for development of the record in a collateral proceeding. People v. Martinez, 2025 Guam 17, Opinion Page 9 of 24
charged crime over the client’s intransigent objection to that admission.” Id. at 426 (emphasis
added); see also id. at 420 (“We granted certiorari in view of a division of opinion among state
courts of last resort on the question whether it is unconstitutional to allow defense counsel to
concede guilt over the defendant’s intransigent and unambiguous objection.” (emphasis added)).
The majority further explained:
If a client declines to participate in his defense, then an attorney may permissibly guide the defense pursuant to the strategy she believes to be in the defendant’s best interest. Presented with express statements of the client’s will to maintain innocence, however, counsel may not steer the ship the other way.
Id. at 424. The Court stated it was not applying its ineffective assistance of counsel jurisprudence
because it was “a client’s autonomy, not counsel’s competence,” that was at issue. Id. at 426.
[20] Federal courts have generally interpreted McCoy as imposing two obligations on trial
counsel when they believe conceding guilt is the wisest path: (1) “He must consult with his client,”
and (2) “if the client engages, he may not ‘steer the ship the other way.’” United States v. Hashimi,
110 F.4th 621, 629 (4th Cir. 2024) (quoting McCoy, 584 U.S. at 424). “If the lawyer violates these
rules and thus ‘usurp[s] control of an issue within [the defendant’s] sole prerogative,’ the remedy
is a new trial, regardless of whether prejudice can be demonstrated.” Id. (alterations in original)
(quoting McCoy, 584 U.S. at 426-27). In other words, McCoy established that “[v]iolation of a
defendant’s Sixth Amendment-secured autonomy” is a structural error. See McCoy, 584 U.S. at
427.
[21] Given the relative newness of the decision, there is uncertainty whether McCoy applies in
non-capital cases. See, e.g., Aroz v. Covello, No. 2:21-cv-1934 DJC CSK P, 2024 WL 3792388,
at *46 (E.D. Cal. Aug. 13, 2024) (collecting district court cases); Harris v. State, 856 S.E.2d 378,
383 n.7 (Ga. Ct. App. 2021) (“We note that there is some uncertainty as to whether McCoy’s
holding extends to non-capital cases.”). People v. Martinez, 2025 Guam 17, Opinion Page 10 of 24
b. Claims of ineffective assistance of counsel and violations of McCoy are not mutually exclusive
[22] Although a McCoy claim is based on the Sixth Amendment, it is not necessarily an
ineffective assistance of counsel claim. See Krogmann v. State, 914 N.W.2d 293, 318 (Iowa 2018)
(“[I]t is important . . . to distinguish between claims of ineffective assistance of counsel and other
claims based on the Sixth Amendment . . . .” (citing McCoy, 584 U.S. at 426)). The McCoy
majority emphasized that review under the ineffective assistance rubric was not apt because (1)
their decision focused on “a client’s autonomy, not counsel’s competence,” and (2) a violation of
autonomy was structural error where prejudice is presumed. See 584 U.S. at 426. However, as
the dissenters noted, it is “hard to imagine a situation in which a competent attorney might take”
the approach of conceding guilt on all charges in a non-capital case. Id. at 433 (Alito, J.,
dissenting). And furthermore, the Supreme Court’s decision in United States v. Cronic, 466 U.S.
648, 657, 666 (1984), establishes that there are certain scenarios where counsel’s deficient
performance is presumed to be prejudicial—where there has been an “actual breakdown of the
adversarial process.” Thus, although the Sixth Amendment separately protects a client’s autonomy
and right to effective assistance of counsel, both rights may be violated when trial counsel concedes
their client’s guilt.
[23] Before McCoy, other courts had found that a concession of guilt could violate a defendant’s
Sixth Amendment right to counsel. For example, over 25 years before McCoy, the Ninth Circuit
recognized that “[w]hen a defense attorney concedes that there is no reasonable doubt concerning
the only factual issues in dispute, the Government has not been held to its burden of persuading
the jury that the defendant is guilty.” United States v. Swanson, 943 F.2d 1070, 1073 (9th Cir.
1991). In Swanson, the Ninth Circuit held that such claims should be evaluated under the
ineffective assistance standard articulated in Cronic where prejudice is presumed. See id. at 1072 People v. Martinez, 2025 Guam 17, Opinion Page 11 of 24
(citing Cronic, 466 U.S. 648). In 1985, the North Carolina Supreme Court held that “ineffective
assistance of counsel, per se in violation of the Sixth Amendment, has been established in every
criminal case in which the defendant’s counsel admits the defendant’s guilt to the jury without the
defendant’s consent.” State v. Harbison, 337 S.E.2d 504, 507-08 (N.C. 1985). North Carolina
courts refer to a claim of per se ineffective assistance based on concession of guilt as a “Harbison
claim.”4 E.g., State v. Maniego, 594 S.E.2d 242, 246 (N.C. Ct. App. 2004).
[24] In the early 2000s, the Florida Supreme Court relied in part on Harbison and other North
Carolina decisions, see Nixon v. Singletary, 758 So. 2d 618, 623, 625 (Fla. 2000) (per curiam)
(citing Harbison, 337 S.E.2d at 504, 507; State v. House, 456 S.E.2d 292, 297 (N.C. 1995)), when
it held trial counsel is per se ineffective “[w]ithout a client’s affirmative and explicit consent to a
strategy of admitting guilt to the crime charged,” Nixon v. State, 857 So. 2d 172, 176 (Fla. 2003)
(per curiam). However, this decision was reversed by the U.S. Supreme Court in Florida v. Nixon,
543 U.S. 175 (2004).5
[25] In Nixon, the Supreme Court held that defense counsel’s failure to obtain defendant’s
express consent to a strategy of conceding guilt at the guilt phase of a capital trial did not
automatically render counsel’s performance deficient. 543 U.S. at 178. The Court stated that trial
4 The North Carolina Supreme Court has stated that “an on-the-record exchange between the trial court and the defendant is the preferred method of determining whether the defendant knowingly and voluntarily consented to an admission of guilt during closing argument,” but it has also “declined to define such a colloquy as the sole measurement of consent or to set forth strict criteria for an acceptable colloquy.” State v. Thompson, 604 S.E.2d 850, 879 (N.C. 2004). When no colloquy occurred, North Carolina courts have ordered limited remand to hold an evidentiary hearing “for the sole purpose of determining whether defendant knowingly consented to trial counsel’s concessions of defendant’s guilt to the jury.” See State v. Thomas, 397 S.E.2d 79, 80 (N.C. 1990). 5 The U.S. Supreme Court’s decision in Nixon called into question state court decisions like Harbison on which the lower court had relied. See Nixon v. Singletary, 758 So. 2d 618, 623, 625 (Fla. 2000) (per curiam) (citing State v. Harbison, 337 S.E.2d 504, 504, 507 (N.C. 1985)), rev’d and remanded, 543 U.S. 175 (2004). North Carolina has continued to follow Harbison after Nixon (and after McCoy), but it may be doing so on state law grounds. See State v. Maready, 695 S.E.2d 771, 779 & n.3 (N.C. Ct. App. 2010) (observing that Nixon did not hold Harbison ran afoul of U.S. Constitution and that state courts may set procedural and substantive requirements “that exceed the constitutional minimum established by the United States Supreme Court”). Because Martinez does not brief these state court decisions addressing concessions of guilt, we find this case is a poor candidate to determine whether a Harbison-like colloquy procedure should be adopted, or whether such a procedure is required under the Organic Act. People v. Martinez, 2025 Guam 17, Opinion Page 12 of 24
counsel’s “concession of Nixon’s guilt [did] not rank as a ‘fail[ure] to function in any meaningful
sense as the Government’s adversary.’” Id. at 190 (second alteration in original) (quoting Cronic,
466 U.S. at 666). The Court also emphasized the unique nature of capital murder trials, observing
that “[a]lthough such a concession in a run-of-the-mine trial might present a closer question, the
gravity of the potential sentence in a capital trial and the proceeding’s two-phase structure vitally
affect counsel’s strategic calculus.” Id. at 190-91. Thus, while Nixon may have undermined state
court decisions that have found a concession of guilt without the defendant’s consent to be per se
ineffective, Nixon still considered an attorney’s concession of guilt under an ineffective assistance
framework.
[26] The Supreme Court did not overrule Nixon in McCoy; rather, the Court left undisturbed the
holding that “when counsel confers with the defendant and the defendant remains silent, neither
approving nor protesting counsel’s proposed concession strategy, ‘[no] blanket rule demand[s] the
defendant’s explicit consent’ to implementation of that strategy.” McCoy, 584 U.S. at 417
(alterations in original) (quoting Nixon, 543 U.S. at 181, 192). Notably, both Nixon and McCoy
were death penalty cases, and both suggest that it may be ineffective to concede guilt in non-capital
cases. See McCoy, 584 U.S. at 433 (Alito, J., dissenting) (explaining that it is “hard to imagine” a
non-capital case in which a competent attorney would choose to concede his client’s guilt at trial);
Nixon, 543 U.S. at 190-91 (“[S]uch a concession in a run-of-the-mine trial might present a closer
question . . . .”).
[27] Courts generally view McCoy and Nixon as capable of being harmonized. See, e.g., United
States v. Rosemond, 958 F.3d 111, 119 (2d Cir. 2020) (analyzing concession of guilt under both
autonomy and ineffective assistance frameworks). Neither case requires a colloquy on the record
before pursuing a strategy involving concession of guilt: People v. Martinez, 2025 Guam 17, Opinion Page 13 of 24
We have no occasion to decide whether an on-the-record colloquy with the court is a necessary predicate to a lawyer’s concession of guilt at trial. But defense counsel planning to concede their client’s guilt at trial might be well advised, under McCoy, to put their consultations with their clients on the record. We of course have no desire to add to the burdens of trial courts in conducting criminal trials. But we trust it will be the rare case, particularly outside the capital-case context of McCoy and Nixon, in which defense counsel will think it advisable to concede a client’s guilt to the jury.
Hashimi, 110 F.4th at 631 n.5 (citations omitted). Thus, while a concession of guilt may run afoul
of multiple constitutional rights, there is no federal right to a colloquy before a concession of guilt.
[28] The Sixth Amendment protects a client’s autonomy to assert their innocence at trial; it also
ensures the effective assistance of counsel. Depending on the circumstances, when defense
counsel concedes guilt without consent, this may override the defendant’s autonomy in violation
of McCoy, result in the breakdown of the adversarial process under Cronic, or both.
2. Courts generally hold that McCoy claims must be preserved in the trial record to be reached on direct appeal
[29] While this court has reiterated that ineffective assistance claims are better raised in
collateral proceedings, McCoy claims are often addressed on direct appeal—including in McCoy
itself, which arose on direct review. See 584 U.S. at 420. Thus, the preference for ineffective
assistance claims to be brought in post-conviction proceedings does not necessarily extend to
McCoy claims. But as this court’s previous order stressed, when the trial record is silent on
counsel’s consultation and the client’s consent, there is nothing for this court to review on direct
appeal. Order at 3 (June 4, 2025).
[30] Texas courts have found that a “defendant cannot simply remain silent before and during
trial and raise a McCoy complaint for the first time after trial.” Turner v. State, 570 S.W.3d 250,
276 (Tex. Crim. App. 2018). But this is not the harsh standard Martinez makes it out to be. See
Appellant’s Br. at 11-12; Digital Recording at 10:24:15-10:25:43 (Oral Arg., Oct. 20, 2025)
(arguing this language from Turner “turns McCoy on its head”). In Turner, the court explained People v. Martinez, 2025 Guam 17, Opinion Page 14 of 24
that to preserve a McCoy claim for appellate review, a defendant “should not be expected to object
with the precision of an attorney,” and that it was sufficient for the defendant to timely make an
“express statement[] of [his] will to maintain innocence” somewhere in the record. Id. (second
alteration in original) (footnotes omitted).
[31] The California Court of Appeal has gone a step further, observing, “[W]e do not think
preservation of the Sixth Amendment right recognized in McCoy necessarily turns on whether a
defendant objects in court before his or her conviction.” People v. Eddy, 244 Cal. Rptr. 3d 872,
879 (Ct. App. 2019); see also Hashimi, 110 F.4th at 630 n.4 (“Of course, a client could . . . stand
up in open court and disavow his lawyer’s concession. But we do not craft legal rules to encourage
clients to speak out of turn in court, and, had [defendant] done so, the district court doubtless would
have responded . . . with an admonition that the court ‘would not permit any other outbursts.’”
(citation modified) (quoting McCoy, 584 U.S. at 419)). Instead, to reach a McCoy claim on direct
appeal, California courts require that “the record must show (1) that defendant’s plain objective is
to maintain his innocence and pursue an acquittal, and (2) that trial counsel disregards that
objective and overrides his client by conceding guilt.” Eddy, 244 Cal. Rptr. 3d at 879.
[32] Martinez has failed to direct this court to the decision of any appellate court that has
entertained a McCoy claim on direct appeal when faced with a silent record.6 Thus, we decline to
do so here.

6 As discussed above, North Carolina courts will order a limited remand to develop a Harbison claim. See State v. Crump, 848 S.E.2d 501, 507 (N.C. Ct. App. 2020) (“McCoy did not change our Harbison landscape.”). But Harbison claims deal with ineffective assistance, and Martinez vociferously argues her claim must not be treated as such. See Appellant’s Reply Br. at 6-7 (Aug. 7, 2025) (“Forcing McCoy claims into the ineffective assistance framework undermines their constitutional significance and subjects defendants to inappropriate procedural hurdles.”). People v. Martinez, 2025 Guam 17, Opinion Page 15 of 24
3. Limited remand to develop all Sixth Amendment claims—including both ineffective assistance and McCoy—may be salutary, but Martinez offers little justification for such a significant departure from established practice
[33] This court unambiguously instructed Martinez not to raise a McCoy claim in her opening
brief if the record was silent. Yet she does just that. An attorney should zealously represent the
interests of their clients—especially criminal defendants—and this includes pushing back against
a court when they believe a decision is wrong. See, e.g., Conklin v. Warrington Twp., Civil Action
No. 1:05-CV-1707, 2006 WL 2246415, at *2 (M.D. Pa. Aug. 4, 2006) (“When an attorney is of
the opinion that the court has issued an erroneous ruling, it is his or her duty as an advocate to seek
reconsideration or clarification of that ruling.”), aff’d, 304 F. App’x 115 (3d Cir. 2008). But there
is a sharp distinction between zealous advocacy and seemingly disregarding a court order without
explanation. Martinez contends:
[T]his case presents the Court with a matter of first impression in Guam: whether a McCoy claim may be raised on direct appeal where the record clearly shows that trial counsel concedes guilt, but contains no evidence of consultation or consent. While Turner required that express objection, other courts – including the Fourth Circuit in United States v. Hashimi, 110 F.4th 621 (4th Cir. 2024) – have adopted a more faithful interpretation of McCoy and Nixon where the first inquiry is whether trial counsel consulted with the defendant before conceding guilt.
Appellant’s Br. at 11-12. If this court had overlooked the precedent of “other courts” referenced
by Martinez, it would be inclined to reconsider its order. However, Martinez did not raise the
Hashimi decision or decisions of “other courts” in her motion, and the cases she raises in later
briefing are inapposite.
[34] It is incorrect to claim Hashimi supports the proposition that a McCoy claim should be
heard on direct appeal when the record is silent. That case was an appeal from a post-conviction
motion under 28 U.S.C. § 2255, which essentially fills the role of a habeas petition in the federal People v. Martinez, 2025 Guam 17, Opinion Page 16 of 24
system.7 See Hashimi, 110 F.4th at 622-24. None of the cases Martinez cites hold that a McCoy
claim can or should be heard on direct appeal when the record is silent. See Appellant’s Br. at 15
(citing United States v. Arrington, Crim. Action No. 19-0532-TDC, 2025 WL 815414 (D. Md.
Mar. 12, 2025); United States v. Schaffer, 731 F. Supp. 3d 382, 392 (N.D.N.Y. 2024)). Rather, all
the cited authorities required the development of facts outside the trial record in a post-conviction
proceeding before adjudicating the defendant’s McCoy claim. See Hashimi, 110 F.4th at 624
(remanding for post-conviction hearing under § 2255 for further factual development); Arrington,
2025 WL 815414, at *1 (granting § 2255 motion after evidentiary hearing); Schaffer, 731 F. Supp.
3d at 386 & n.5 (granting motion for new trial based on affidavits).
[35] Martinez claims that “the Government argues this right arises only if a defendant expressly
objects on the record to counsel’s concession strategy.” Appellant’s Reply Br. at 1 (Aug. 7, 2025).
But this mistakes the existence of a right with preservation of an issue for appellate review. While
the Sixth Amendment-secured autonomy right to make choices about conceding guilt to a jury
exists independent of what the record reveals, on a fundamental level, appellate courts must have
an adequate record to make a decision. See, e.g., Grimm v. Fox, 33 A.3d 205, 212 n.12 (Conn.
2012) (“Providing this court with an adequate record for review is a basic rule of appellate
procedure in that this court is incapable of meaningful review of a claim without an adequate
record.”). When faced with an analogous request, the Eighth Circuit declined a request for remand
so a McCoy claim could be addressed on direct appeal. United States v. Felicianosoto, 934 F.3d
783, 787 (8th Cir. 2019).
7 At oral argument, Martinez asserted that Guam has no similar post-conviction statute or rule. See Digital Recording at 10:05:14-10:05:39, 10:16:30-10:17:53 (Oral Arg., Oct. 20, 2025). But in the absence of any post- conviction legislation, Martinez fails to articulate what standards or procedures this court should adopt. See People v. Adriatico, 2024 Guam 7 ¶ 14 (“[T]he Superior Court can properly exercise its general jurisdiction to consider post- conviction motions if they are not explicitly barred by statute.”). People v. Martinez, 2025 Guam 17, Opinion Page 17 of 24
[36] To some extent, Martinez is correct that this case presents an issue of first impression and,
therefore, this court has the authority to decide for itself how these claims should be preserved and
raised. See Appellant’s Br. at 11-12; cf. Yokeno v. Lai, 2014 Guam 18 ¶ 14 (“This is a question of
first impression in our court, so we will examine, analyze, and weigh the three approaches appellate
courts appear to take in dealing with such cases.”); May v. People, 2005 Guam 17 ¶ 20 (“This is
an issue of first impression in our jurisdiction, and we must decide whether this court wishes to
follow a majority of states . . . .”). But this ignores the prior order we issued in this case and this
court’s Sixth Amendment jurisprudence. The argument that Sixth Amendment claims should be
heard on direct appeal—even if a limited remand is required to develop facts outside the trial
record—is non-frivolous.8 However, Martinez does not address three decades of this court’s
precedent holding that habeas proceedings are preferable when facts need to be developed outside
the trial record.9
[37] Although there is a non-frivolous argument for this court to revisit its precedent on limited
remand, Martinez largely fails to make it. Instead, she raises three non sequiturs to prioritize
remand over habeas. First, she contends that “McCoy violations concern structural constitutional
8 See, e.g., Brent E. Newton, Incentivizing Ineffective-Assistance-of-Counsel Claims Raised on Direct Appeal: Why Appellate Courts Should Remand “Colorable” Claims for Evidentiary Hearings, 22 J. App. Prac. & Process 107, 116 (2022) (“Particularly after the Supreme Court’s 2012 decision in Martinez v. Ryan, there are at least five reasons why, if a defendant represented by new counsel on direct appeal identifies a colorable claim of ineffective assistance of counsel by his trial court counsel, an appellate court should remand for an evidentiary hearing rather than relegate the defendant to raising the claim in habeas corpus proceedings.” (footnote omitted)). For the past 40 years, the North Carolina Supreme Court has required limited remand in cases when trial counsel concedes guilt, although Martinez appears ignorant of this jurisprudence. See Harbison, 337 S.E.2d at 507-08; see also Thomas, 397 S.E.2d at 80 (remanding case to superior court for evidentiary hearing to determine whether defendant knowingly consented to trial counsel’s concessions of defendant’s guilt to jury). Additionally, it seems that both the First Circuit and D.C. Circuit employ limited remand to develop ineffective assistance claims on direct appeal. See United States v. Colón- Torres, 382 F.3d 76, 84-85 (1st Cir. 2004); United States v. Rashad, 331 F.3d 908, 909-10 (D.C. Cir. 2003). 9 In over a dozen published opinions, this court has instructed defendants to develop a factual record in a collateral proceeding. See generally People v. Ueki, 1999 Guam 4; People v. Root, 1999 Guam 25; People v. Hall, 2004 Guam 12; People v. Aguirre, 2004 Guam 21; People v. Meseral, 2014 Guam 13; People v. Damian, 2016 Guam 8; People v. Guerrero, 2017 Guam 4; People v. Roberson, 2017 Guam 18; People v. Nathan, 2018 Guam 13; People v. Quintanilla, 2019 Guam 25; People v. Titus, 2020 Guam 16; People v. Reyes, 2020 Guam 33; People v. Taisacan, 2023 Guam 19; People v. Narruhn, 2025 Guam 11. People v. Martinez, 2025 Guam 17, Opinion Page 18 of 24
error, not ineffective assistance of counsel. McCoy claims are fundamentally different from
ineffective assistance claims because they concern the defendant’s autonomy rather than counsel’s
competence.” Appellant’s Br. at 12. The Supreme Court in McCoy did not apply its ineffective
assistance of counsel jurisprudence “[b]ecause a client’s autonomy, not counsel’s competence,
[was] in issue . . . .” 584 U.S. at 426. But McCoy and Cronic/Nixon are not mutually exclusive
Sixth Amendment claims. See, e.g., Jurado v. Davis, 12 F.4th 1084, 1101 (9th Cir. 2021)
(“[C]ounsel’s tactics did not run afoul of Nixon or McCoy.”). This argument ignores decisions
like Swanson that find such a concession of guilt undermines the adversarial process and is subject
to Cronic’s presumption of prejudice. See Swanson, 943 F.2d at 1072-73; see also People v.
Soram, 2024 Guam 10 ¶ 45 (quoting Swanson and agreeing that concession of guilt without client’s
consent is per se deficient performance). There is substantial overlap between a McCoy claim and
ineffective assistance of counsel; as the dissent observed in McCoy, one would be hard pressed to
conceive of a McCoy violation where counsel was not also ineffective. See McCoy, 584 U.S. at
433 (Alito, J., dissenting).
[38] The second argument Martinez makes is a contradictory claim that no facts outside the trial
record need development because “[t]he only factual question is whether Martinez was consulted
or consented, which can be readily addressed through remand proceedings that allow both
Martinez and trial counsel to testify about their communications.” See Appellant’s Br. at 13. But
arguing that an evidentiary hearing on limited remand would do anything but develop facts outside
the trial record is incorrect. If the record is silent, then the trial record must be supplemented. See
State v. McAllister, 847 S.E.2d 711, 724-25 (N.C. 2020). For most Sixth Amendment claims, this
court has expressed a preference for supplementing the record in post-conviction proceedings
rather than via limited remand. See cases cited supra note 9. The purpose of the evidentiary
hearing requested by Martinez would be to supplement a silent record; the incorrect assertion that People v. Martinez, 2025 Guam 17, Opinion Page 19 of 24
this would somehow not be an “evidentiary inquiry beyond the official record,” People v. Cruz,
2023 Guam 1 ¶ 7, does nothing to dislodge our procedural preference for collateral proceedings.
[39] The third unpersuasive argument Martinez makes is that “requiring habeas proceedings”
for unpreserved McCoy claims would create a “a dangerous precedent” that would “effectively
immunize trial attorneys from McCoy violations simply by failing to create a record of
consultation.” Appellant’s Br. at 14. Martinez further claims this would create a “perverse
incentive” for defense attorneys “to avoid discussing concession strategies with their clients” and
would “undermine the core protection that McCoy was designed to provide.” Id. at 14. But
Martinez provides no support for these conclusory statements.
[40] Nothing about a post-conviction proceeding should “immunize” the actions of trial counsel
from review.10 Martinez implies that habeas proceedings do not adequately protect a defendant’s
constitutional rights. See Appellant’s Br. at 19. The implications of this argument are serious, but
she does nothing to explain why this is the case, or how this court might exercise its supervisory
authority to remedy this alleged injustice. Cf. Tumon Partners, LLC v. Shin, 2008 Guam 15 ¶ 18
(“This case fails to present any extraordinary circumstances warranting the use of our supervisory
authority.”).
10 As one leading treatise explains: “It is natural for a lawyer to take ineffective assistance claims personally, but they should not be. . . . Ineffective assistance claims should, more properly, be characterized as a challenge to the legitimacy of the process that led to the conviction and not the lawyer’s culpability. . . . The former client desperately needs former counsel’s help . . . .” John Wesley Hall, Jr., Prof. Resp. Crim. Def. Prac. § 10:69 (4th ed. (Feb. 2025 Update)) (footnotes omitted). Martinez appears to subscribe to this fallacy that an ineffective assistance claim is an adjudication of a defense attorney’s culpability or skill. To the extent this sentiment is widely shared, we correct this misunderstanding: “[A]s to a former client, the lawyer must: do no harm to the client; cooperate with post-conviction counsel and deliver files; protect confidentiality of the client’s secrets, to the extent possible; and be completely candid in the post-conviction proceeding.” Id. § 10:71 (footnotes omitted). “[F]ormer defense counsel has a duty to aid post- conviction counsel in identifying legal and factual issues which could be pursued, and this includes a duty of candor where former counsel may believe he or she was ineffective.” Id. § 10:74 (footnote omitted). “Many criminal defense lawyers, as they should, subscribe to th[e] view” that “[s]ometimes, former counsel will have to ‘fall on his sword’ and admit fault. One should not fear the outcome. Being found ineffective is not the end of the world and may not even harm one’s reputation.” Id. People v. Martinez, 2025 Guam 17, Opinion Page 20 of 24
[41] The strongest argument raised by Martinez to favor remand over post-conviction
proceedings is judicial economy. Martinez argues:
[R]emand for factual development ensures that McCoy violations are addressed promptly and prevents the waste of judicial resources inherent in requiring separate habeas proceedings. A defendant who successfully establishes a McCoy violation is entitled to a new trial regardless of whether the claim is raised on direct appeal or in habeas. By addressing the issue on direct appeal through remand, the Court can resolve the constitutional violation efficiently while ensuring adequate factual development.
Appellant’s Br. at 13. This echoes the sentiment of legal scholars who have argued that “because
a defendant would be entitled to an evidentiary hearing if he or she raises a colorable
ineffectiveness claim in a habeas petition, the remedy of remand on direct appeal is simply an
earlier expenditure of the financial and judicial recourses that would be justified at a later point in
the case.” See Brent E. Newton, Incentivizing Ineffective-Assistance-of-Counsel Claims Raised on
Direct Appeal: Why Appellate Courts Should Remand “Colorable” Claims for Evidentiary
Hearings, 22 J. App. Prac. & Process 107, 129 (2022) (footnotes omitted).
[42] But it is not categorially true that limited remand will conserve judicial resources in all
cases. For instance, when other reversible errors are present, a limited remand may delay a
defendant receiving relief. Cf. People v. Meseral, 2014 Guam 13 ¶ 87 (passing on ineffective
assistance claim because sentence was reversed on other grounds). When a concession of guilt on
an otherwise silent record is the strongest (or only) issue that could be raised on appeal, limited
remand may conserve judicial resources. Whenever a defendant requests a limited remand under
8 GCA § 130.60, she would do well to address whether remand will promote judicial economy.
Where an evidentiary inquiry beyond the official record may be necessary to rule on a defendant’s
Sixth Amendment claims, appellate counsel should inform this court whether other potential trial
errors exist when they ask us to invoke our authority under section 130.60. Cf. Guam R. App. P.
35 (requiring counsel to identify any potentially non-frivolous issues). Furthermore, we note that People v. Martinez, 2025 Guam 17, Opinion Page 21 of 24
our appellate rules permit the filing of affidavits in support of motions. See Guam R. App. P. 6.
Our resolution of a motion for limited remand to develop a McCoy claim would be greatly aided
if it was accompanied by affidavits from the defendant or trial counsel sworn under penalty of
perjury.11 Cf. Schaffer, 731 F. Supp. 3d at 386 & n.5 (resolving new trial motion based on
affidavits, because they rendered evidentiary hearing unnecessary).
[43] A remand would not conserve judicial resources here. Martinez has not convinced us that
the interests of justice require remand rather than a habeas proceeding.
[44] We are sympathetic to Martinez’s argument that requiring criminal defendants “to
spontaneously object places an impossible burden on the most vulnerable.” Reply Br. at 5. On
this point, we agree with the California Court of Appeal that “preservation of the Sixth Amendment
right recognized in McCoy [should not] necessarily turn[] on whether a defendant objects in court
before his or her conviction.” See Eddy, 244 Cal. Rptr. 3d at 879; see also Turner, 570 S.W.3d at
276 (“[A] defendant faced with a McCoy issue should not be expected to object with the precision
of an attorney.”). But this court cannot presume a defendant’s Sixth Amendment rights were
violated on a silent record. See State v. Meadows, 916 S.E.2d 578, 583-84 (N.C. Ct. App. 2025)
(“[T]he absence of any indication in the record of defendant’s consent to his counsel’s admissions
will not—by itself—lead us to ‘presume defendant’s lack of consent.’” (citation omitted)).
[45] To some extent, we agree with Martinez. See Appellant’s Br. at 14-15. Decisions like
Hashimi articulate the correct standard that should be applied by trial courts after holding an
evidentiary hearing. Generally, when evaluating a McCoy claim, courts must determine whether
trial counsel: (1) consulted with his client and (2) overrode his client’s autonomy by conceding
11 We note that appellate counsel filed a declaration supporting his motion, which described representations made by Martinez about concessions of guilt. Decl. Counsel Supp. Mot. Ltd. Remand (Apr. 21, 2025). But these representations were not made by Martinez under penalty of perjury. People v. Martinez, 2025 Guam 17, Opinion Page 22 of 24
guilt after express statements of the client’s will to maintain innocence. See McCoy, 584 U.S. at
424; Hashimi, 110 F.4th at 629; Eddy, 244 Cal. Rptr. 3d at 879.
[46] But this court is still left to grapple with how to apply that standard when the record is
silent. Ultimately, in this case, we cannot apply a standard absent a post-conviction evidentiary
hearing. This court’s stated preference is for supplementation of the factual record to occur in a
habeas proceeding. See cases cited supra note 9. Although several legal scholars and sister courts
have raised valid questions about this preference, Martinez has not.
[47] Because the McCoy claim is the only issue raised on direct appeal, and we cannot conclude
whether Martinez was consulted or consented to a concession of guilt, we affirm without prejudice
to Martinez’s right to litigate her claim in collateral proceedings.
B. We Appoint Martinez Habeas Counsel
[48] “When presented with a petition for a writ of habeas corpus, a court must first determine
whether the petition states a prima facie case for relief—that is, whether it states facts that, if true,
entitle the petitioner to relief . . . .” People v. Romero, 883 P.2d 388, 391 (Cal. 1994) (in bank);
cf. May v. People, 2005 Guam 17 ¶ 9 (finding California habeas caselaw persuasive absent
compelling reason to deviate because Guam’s habeas statutes were derived from California). In a
typical habeas case, a court does not appoint counsel until the petitioner first establishes a prima
facie claim for relief. Cf. In re Clark, 855 P.2d 729, 748 (Cal. 1993) (in bank) (finding no federal
constitutional right to counsel to collaterally attack a judgment but noting its precedent that “if a
petition attacking the validity of a judgment states a prima facie case leading to issuance of an
order to show cause, the appointment of counsel is demanded by due process concerns”),
superseded by statute on other grounds, Cal. Prop. 66, Death Penalty Reform and Savings Act of
2016 (approved in Gen. Elec., Nov. 8, 2016), as recognized in, In re Friend, 489 P.3d 309 (Cal.
2021). However, the U.S. Supreme Court has suggested, without holding, that a prisoner may People v. Martinez, 2025 Guam 17, Opinion Page 23 of 24
have “a right to effective counsel in collateral proceedings which provide the first occasion to raise
a claim of ineffective assistance at trial.” Martinez v. Ryan, 566 U.S. 1, 8-9 (2012); accord People
v. Narruhn, 2025 Guam 11 ¶ 58 n.17.12
[49] That the trial record does not disclose whether Martinez was consulted or consented to a
concession of guilt does not mean such a claim should be summarily denied in collateral
proceedings. The facts as presented by Martinez, if true, would entitle her to relief under McCoy.
As such, we exercise our discretion to appoint habeas counsel to represent Martinez. Attorney
Leevin T. Camacho is appointed as counsel for Martinez to file and litigate a petition for a writ of
habeas corpus.
V. CONCLUSION
[50] A McCoy claim may be raised on direct appeal only if the client’s objection to counsel’s
concession of guilt appears somewhere in the record. As a matter of preservation, this court cannot
presume a constitutional violation from a silent record. Unless a litigant persuades us that we need
to revisit our Sixth Amendment jurisprudence, where the record is silent, the proper avenue is to
raise a claim challenging concession of guilt in a habeas proceeding based on Cronic/Nixon or
McCoy. Although there may be policy reasons habeas is not the ideal vehicle for addressing Sixth
Amendment claims—as opposed to limited remand on direct appeal—Martinez’s arguments are
unpersuasive.
12 The Fourteenth Amendment’s Due Process Clause also provides for a right to counsel in certain post- conviction proceedings when “fundamental fairness necessitates the assistance of a trained advocate.” United States v. Palomo, 80 F.3d 138, 141 (5th Cir. 1996). Additionally, the California Supreme Court has held that due process demands the appointment of counsel where a habeas petition states a prima facie claim for relief. In re Clark, 855 P.2d 729, 748 (Cal. 1993) (in bank), superseded by statute on other grounds, Cal. Prop. 66, Death Penalty Reform and Savings Act of 2016 (approved in Gen. Elec., Nov. 8, 2016), as recognized in, In re Friend, 489 P.3d 309 (Cal. 2021). Because we find it appropriate to appoint counsel in this case sua sponte, and Martinez does not argue she has a right to habeas counsel, we need not determine whether there is a right to post-conviction counsel in all cases where the record is insufficiently developed to address a claim on direct appeal. People v. Martinez, 2025 Guam 17, Opinion Page 24 of 24
[51] The record is not complete enough to determine whether trial counsel consulted Martinez
about conceding guilt to the jury, nor does it disclose whether Martinez consented to this tactic.
We cannot make definitive findings based on the current record, and because Martinez fails to
persuade us that limited remand would be appropriate, we appoint Martinez habeas counsel with
instructions to file a writ of habeas corpus in the Superior Court. We AFFIRM WITHOUT
PREJUDICE to Martinez’s right to raise her claims in a habeas corpus proceeding.13

13 Although our focus is specifically on the McCoy claim raised on direct appeal, the general rule is that all potential claims cognizable on habeas review should be raised in the first petition, and subsequent claims that could have been raised in the first petition are generally barred. See In re Friend, 489 P.3d at 315 (explaining “successiveness bar” ensures “legitimate claims are pressed early in the legal process” and “limits consideration of claims that were unjustifiably omitted from earlier petitions”).
