v. No. 24-8073 (D.C. Nos. 1:08-CV-00097-SWS RAYMOND DEAN BROWN, & 2:00-CR-00059-SWS-1) (D. Wyo.) Defendant - Appellant. _________________________________
ORDER DENYING CERTIFICATE OF APPEALABILITY * _________________________________
Before HARTZ, MORITZ, and ROSSMAN, Circuit Judges. _________________________________
Raymond Dean Brown, a federal prisoner proceeding pro se, seeks a certificate of
appealability (COA) to challenge the district court’s denial of a motion he filed under
Fed. R. Civ. P. 60(b) in his proceedings under 28 U.S.C. § 2255. We deny Brown’s
request for a COA and dismiss this matter.
I. Background
Brown was arrested in a Wyoming parking lot in 1999. A vehicle search
uncovered a machine gun, and a search of his residence uncovered a methamphetamine
manufacturing operation. While state drug and firearm charges were pending against

him, Brown and his attorney met with a state prosecutor to determine if the state would
offer him a deal in exchange for information. Also attending this “proffer meeting” was
Dennis Claman, a deputy sheriff with the Sweetwater County Sheriff’s Office assigned as
a task force special agent with the Wyoming Division of Criminal Investigation. Brown
and his attorney had requested the proffer meeting to share information about an alleged
murder. According to testimony Claman provided at Brown’s federal trial, the state
prosecutor informed Brown that although any information he provided at the meeting
“would not be used against him in state court, the state could not bind federal
authorities.” United States v. Brown (Brown I), 400 F.3d 1242, 1246 (10th Cir. 2005).
“Brown expressly acknowledged that he understood these terms.” Id. at 1255–56.
According to Claman, Brown said he knew the identity and address of the man “who
made that gun” and had “‘converted [Brown’s] gun to full auto[matic] in Illinois.’”
R. vol. 2 at 36–37 (district court order denying § 2255 relief, quoting Trial Tr. vol. 3
at 437–38). Brown’s attorney then advised him not to say anything else about the gun.
Claman later informed federal agents about Brown’s knowledge of the altered gun and its
fabricator.
Brown pleaded nolo contendere to two state drug charges, and the state dismissed
two other charges. A week later, a federal grand jury indicted Brown on three charges:
felon in possession of a firearm, unlawful possession of a machine gun, and carrying a
machine gun during and in relation to a drug trafficking crime. The federal prosecutor
designated Claman as the case agent in the federal case. Brown filed a pretrial motion to
suppress the statements he made at the proffer meeting. The district court reserved ruling
2 Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 3
on the motion. Brown did not renew the motion at trial, and the government presented
his proffer-meeting statements through Claman’s testimony without objection.
A jury convicted Brown on all three charges. We affirmed his convictions but
remanded for resentencing. On remand, the district court sentenced Brown to 30 years’
imprisonment on the conviction for carrying a machine gun during and in relation to a
drug-trafficking crime, to be served consecutively to the 30-month sentence on the other
counts. See United States v. Brown (Brown II), 212 F. App’x 747, 750–51 (10th Cir.
2007). We affirmed. See id. at 756.
In 2008 Brown sought relief from his convictions by filing a pro se 28 U.S.C.
§ 2255 motion. He raised numerous claims, including three claims of ineffective
assistance of trial counsel related to the information he provided at the proffer meeting.
The district court denied the § 2255 motion. On appeal we remanded for further
proceedings on the three ineffective-assistance claims. See United States v. Brown
(Brown III), 640 F. App’x 752, 756 (10th Cir. 2016).
On remand the district court appointed counsel for Brown, ordered supplemental
briefing, held an evidentiary hearing, and accepted additional briefing after the hearing.
In 2021 the district court denied all three ineffective-assistance claims. We denied
Brown a COA to appeal from that ruling. See United States v. Brown (Brown IV),
No. 21-8083, 2022 WL 4103071, at *3 (10th Cir. Sept. 8, 2022).
Brown then filed a motion, through counsel, under Fed. R. Civ. P. 60(b). Brown
argued that the district court had never ruled on a claim he presented in ground two of his
§ 2255 motion—that when the prosecutor introduced Claman’s testimony at Brown’s
3 Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 4
federal trial, the United States breached his state plea agreement. Brown contended that
it was “undisputed” that at the proffer meeting, “Claman was working with both the State
of Wyoming and the federal government.” Suppl. R. at 51. Brown asserted that “federal
prosecutors deliberately chose him as the lead case agent for the federal prosecution, fully
aware of his close involvement with the State of Wyoming, including [at] the proffer
meeting,” id., and this made Claman “an arm of the federal prosecution,” id. at 52.
Brown concluded that Claman breached the plea agreement when he testified about
Brown’s statements at the proffer meeting, and Claman’s breach was “legally equivalent
to” the federal prosecutor’s breaching the agreement and violating the prohibition of Fed.
R. Evid. 410(a) against the use of statements made by a defendant during plea discussions
resulting in a nolo contendere plea. Id. at 54. Brown asked the court to reopen his
§ 2255 proceeding as to ground two and set aside his conviction.
The district court treated the motion as a true Rule 60(b)(4) motion based on a
void judgment and denied it. 1 The court first determined that it would not be error to
decline to rule on Brown’s breach claim because it was not among the
ineffective-assistance claims included in the Brown III remand. But the court then

decline to rule on Brown’s breach claim because it was not among the
ineffective-assistance claims included in the Brown III remand. But the court then
1 See Spitznas v. Boone, 464 F.3d 1213, 1215–16 (10th Cir. 2006) (explaining that a Rule 60(b) motion “is a ‘true’ 60(b) motion” rather than a second or successive habeas petition requiring circuit-court authorization “if it either (1) challenges only a procedural ruling of the habeas court which precluded a merits determination of the habeas application; or (2) challenges a defect in the integrity of the federal habeas proceeding, provided that such a challenge does not itself lead inextricably to a merits-based attack on the disposition of a prior habeas petition”) (citation omitted). 4 Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 5
assumed arguendo that Brown had asserted such a claim in ground two of his § 2255
motion and provided two independent reasons for denying relief.
First, the court concluded that the law-of-the-case doctrine barred the claim
because in Brown’s direct appeal, Brown I, we considered and rejected the argument that
the government breached the plea agreement when it elicited testimony from Claman
regarding the proffer meeting.
Second, the district court concluded that Brown’s Rule 60(b) argument failed on
the merits for multiple, independently sufficient reasons:
(1) The express terms of the agreement between the state prosecutor and Brown
did not bind the United States.
(2) The district court had already determined, following the § 2255 evidentiary
hearing, that Claman was acting only as a Wyoming Division of Criminal Investigation
agent at the proffer meeting, and the court had rejected Brown’s arguments that Claman
was also “simultaneously serving as a federal agent . . . to collect information about the
machine gun at the proffer meeting.” R. vol. 5 at 101.
(3) Claman’s later involvement with the federal prosecution could not
retroactively bind the United States to the terms of Brown’s plea agreement because
Claman lacked actual authority to do so at the time the promise was made to Brown, as
required under United States v. Lilly, 810 F.3d 1205, 1211 (10th Cir. 2016) (“[A]
defendant who seeks specifically to enforce a promise contained in a plea agreement or a
freestanding cooperation agreement, must show that the promisor had actual authority to
make the particular promise.” (ellipses and internal quotation marks omitted)).
5 Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 6
(4) Even if Claman was acting as a federal investigator at any time, he lacked
authority to bind the United States to the agreement unless a federal prosecutor
authorized him to do so. See id. at 1213 (“[O]rdinarily, there is nothing inherent in a
federal investigator’s role that actually authorizes the investigator to make . . . promises
[of immunity]; instead, there must be a showing that the investigator has received
permission or authorization from a governmental actor that actually possesses actual
authority—notably, a federal prosecutor.”). And Brown offered no evidence of such
authorization.
(5) Brown waived Rule 410’s protection because it was defense counsel, not the
United States, who originally introduced the proffer statements when questioning
Claman, thereby opening the door for the prosecutor to elicit further testimony from
Claman regarding those statements.
Accordingly, the district court denied the Rule 60(b) motion. It also denied a
COA. Brown now seeks a COA from this court.
II. Scope of COA review
Brown’s notice of appeal designates three of the district court’s orders as those he
would like to appeal— ECF No. 289, which is the order denying his § 2255 motion; ECF
No. 303, which is the order denying his Rule 60(b) motion; and ECF No. 316, in which
the district court denied three motions Brown filed after the denial of his Rule 60(b)
6 Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 7
motion. But Brown’s COA application challenges only the district court’s order denying
his Rule 60(b) motion. We therefore limit our COA analysis to that order. 2
III. COA standard
To appeal the denial of a Rule 60(b) motion filed in § 2255 proceedings, Brown
must obtain a COA. See 28 U.S.C. § 2253(c)(1)(B) (requiring a COA to appeal the final
order in a § 2255 proceeding); Spitznas v. Boone, 464 F.3d 1213, 1218 (10th Cir. 2006)
(holding “that a COA is required to appeal from the denial of a true Rule 60(b) motion”
filed in habeas proceedings). We will issue a COA “only if the applicant has made a
substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2). This
standard requires the applicant to demonstrate that “reasonable jurists would find the
district court’s assessment of the constitutional claims debatable or wrong.” Slack v.
McDaniel, 529 U.S. 473, 484 (2000). For claims the district court denied on a procedural
ground without reaching the merits, the applicant must also show that the district court’s
procedural ruling is debatable. Id.
IV. Discussion
Brown identifies three issues for appeal: (1) the district court misconstrued his
allegedly overlooked claim; (2) the law-of-the-case doctrine does not apply; and (3) his
2 We note, however, that we would lack jurisdiction to review the order denying the § 2255 motion, which was filed in September 2021, because Brown filed his notice of appeal in October 2024, well beyond the 60-day period applicable in this case. See Bowles v. Russell, 551 U.S. 205, 214 (2007) (timely notice of appeal is a jurisdictional requirement in a civil case); United States v. Pinto, 1 F.3d 1069, 1070 (10th Cir. 1993) (§ 2255 proceedings are considered civil cases for purposes of the appellate rules); Fed. R. App. P. 4(a)(1)(B)(i) (setting a 60-day deadline for a notice of appeal in a civil case where the United States is a party). 7 Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 8
Rule 60(b) argument is meritorious, warranting full briefing by both parties. But even
liberally construing Brown’s pro se pleadings, see Yang v. Archuleta, 525 F.3d 925, 927
n.1 (10th Cir. 2008), we conclude that he has not shown that reasonable jurists would
debate the district court’s construction of his claim or its conclusion that the claim failed
on the merits. We therefore need not address his second issue.
A. The district court did not misconstrue Brown’s claim.
Brown contests the district court’s determination that what his Rule 60(b) motion
alleged was that the district court had overlooked a claim in his § 2255 motion that the
government breached the plea agreement reached in the state case; he contends that the
overlooked claim was a claim of ineffective assistance of counsel. Brown argues that a
reading of ground two of his § 2255 motion and supporting materials shows that the
claim concerning the purported breach of the plea agreement was “raised under the
umbrella of ineffective assistance of counsel.” COA Appl. at 22.
In Brown’s Rule 60(b) motion, however, he did not assert that the district court
had overlooked a claim that counsel provided ineffective assistance with respect to the
breach of the plea agreement. Rather, Brown argued that the court had overlooked his
claim that “[t]he Government breached the nolo contendere plea agreement with . . .
Brown by introducing the testimony of Agent Claman at . . . Brown’s federal criminal
trial.” Suppl. R. at 47; see also id. at 50 (“The record conclusively shows that . . . Brown
raised the claim that the federal government breached the plea agreement by introducing
. . . Claman’s testimony at trial.”); id. at 51 (“In [the district court’s] order denying . . .
Brown’s [§] 2255 motion” after the remand in Brown III, the district court “addressed
8 Appellate Case: 24-8073 Document: 21-1 Date Filed: 10/20/2025 Page: 9
three [ineffective-assistance] claims, none of which included the claim that the federal
government breached the plea agreement.”). Brown, therefore, has not demonstrated that
reasonable jurists would debate whether the district court misconstrued his Rule 60(b)
argument as a stand-alone claim that the United States breached the plea agreement rather
than as an ineffective-assistance claim.
B. Brown has not shown the district court’s merits analysis is debatable.
Brown asserts that the district court’s rejection of his claim on the merits “is
simply wrong.” COA Appl. at 23. In support, however, he does not engage with any of
the district court’s analysis. Instead, he merely reiterates his view that the United States
breached the plea agreement when Claman, as a member of the prosecution team,
testified about Brown’s statements at the proffer meeting. That is insufficient to
demonstrate that reasonable jurists would debate the district court’s rejection of Brown’s
claim on the merits because “[t]he first task of an appellant is to explain to us why the
district court’s decision was wrong.” Nixon v. City & Cnty. of Denver, 784 F.3d 1364,
1366 (10th Cir. 2015). Brown has failed in this regard. The district court provided five
independently sufficient alternative rationales for denying the claim on the merits, and
Brown has addressed none of them.
V. Conclusion
We deny Brown’s application for a COA and dismiss this matter. We also deny his
pending motion to appoint counsel.
