ORDER DENYING CERTIFICATE OF APPEALABILITY*

_________________________________ 

Before HOLMES, KELLY, and ROSSMAN, Circuit Judges. 

_________________________________ 

Petitioner-Appellant William Donnell, III, a state inmate appearing pro se, seeks a 

Certificate of Appealability (COA) to appeal from the district court’s dismissal of his 28 

U.S.C. § 2254 petition. See Donnell v. Caley, No. 21-cv-01372, 2022 WL 622001 (D. 

Colo. Mar. 3, 2022). Exercising jurisdiction under 28 U.S.C. §§ 1291 and 2253(a), we 

deny a COA and dismiss the appeal.

 This order is not binding precedent except under the doctrines of law of the case, 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 Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.

Background 

In November 2015, Mr. Donnell was convicted of first-degree murder after a jury 

trial in Colorado state court. He was sentenced to life imprisonment. The Colorado 

Court of Appeals affirmed his conviction. See People v. Donnell, No. 16CA0425, 2019 

WL 6359267 (Colo. App. Dec. 26, 2019). The Colorado Supreme Court denied his 

petition for a writ of certiorari. Donnell v. People, No. 20SC60, 2020 WL 3420899 

(Colo. June 22, 2020). 

In June 2021, Mr. Donnell filed an amended § 2254 petition raising four claims. 

Based on the Sixth and Fourteenth Amendments, he challenged the trial court’s refusal to 

allow (1) extrinsic evidence to impeach a witness and (2) impeachment of a witness with 

a dismissed drug charge. Based on the Fifth and Fourteenth Amendments, he challenged 

(3) the trial court’s failure to explain its reasoning for rejecting the parties’ plea 

agreement, and he claimed (4) that his due process rights were violated under the 

cumulative error doctrine. 

The district court denied Mr. Donnell’s § 2254 petition. As to claims one and two, 

the district court found that the state appellate court’s decision was not contrary to clearly 

established federal law and was not based on an unreasonable determination of the facts. 

Donnell, 2022 WL 622001, at *7–11. The district court found that the third claim was 

procedurally barred, and alternatively, that it failed on the merits. Id. at *11–14. Finally, 

the district court found that the state appellate court’s denial of relief under the 

cumulative error doctrine was not unreasonable. Id. at *14. Mr. Donnell pursues the 

same claims on appeal.

Discussion 

Mr. Donnell must obtain a COA to appeal his § 2254 petition. See 28 U.S.C. 

§ 2253(c)(1)(A). To obtain a COA, Mr. Donnell must make “a substantial showing of the 

denial of a constitutional right.” Id. § 2253(c)(2). Where a claim has been denied on the 

merits, the movant “must 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). Where a claim has been dismissed on procedural grounds, the 

movant must also demonstrate that the district court’s procedural ruling was debatable. 

Id. State court decisions are reviewed under the highly deferential standards of 28 U.S.C. 

§ 2254(d). 

With respect to the first and second claims, the district court’s assessment of Mr. 

Donnell’s constitutional right to confrontation is not reasonably debatable. The 

Confrontation Clause is violated where a “reasonable jury might have received a 

significantly different impression of [a witness’s] credibility had [defense] counsel been 

permitted to pursue his proposed line of cross-examination.” Delaware v. Van Arsdall, 

475 U.S. 673, 680 (1986). Trial judges have broad discretion to limit the scope of crossexamination based on concerns about jury confusion and relevance. Id. at 679. 

Mr. Donnell’s first claim challenges the trial court’s refusal to allow extrinsic 

evidence to show that a police officer witness made false statements in a prior 

investigation. Donnell, 2022 WL 622001, at *6. Although the trial court prohibited the 

use of extrinsic evidence, in part because it risked confusion of the jury, it allowed 

defense counsel to question the witness about the accusation. Id. Mr. Donnell’s second 

Appellate Case: 22-1093 Document: 010110695308 Date Filed: 06/10/2022 Page: 3

claim challenges the trial court’s refusal to allow defense counsel to question a witness 

about a criminal charge that was dismissed before trial to show that she was biased in 

favor of the prosecution. Id. at *7–8. Regardless, defense counsel cross-examined the 

witness about another prior conviction and other inconsistencies in her testimony. Id. at 

*9. In these two instances, the trial court exercised its broad discretion to impose 

reasonable limits on cross-examination while providing the opportunity for effective 

impeachment. See Van Arsdall, 475 U.S. at 679. The district court’s conclusion that the 

jury would not have received a “significantly different impression” of these witnesses if 

defense counsel could have introduced the proposed evidence is not reasonably 

debatable.1

 See id. at 680; Donnell, 2022 WL 622001, at *7–8. 

As to the third claim, the district court’s conclusion that Mr. Donnell waived this 

claim is not reasonably debatable.2

 A § 2254 petition may not be granted unless all state 

remedies have been exhausted. 28 U.S.C. § 2254(b)(1)(A). Where a state appellate court 

determines that a claim is waived, this constitutes a procedural bar to federal habeas 

review. See Carbajal v. Williams, 844 F. App’x 68, 74 (10th Cir. 2021) (unpublished).3

 

At a pre-trial hearing, the trial court rejected the parties’ plea agreement and invited the 

1

 As to claim two, the district court’s alternative conclusion that the state appellate 

court reasonably applied constitutional harmless error analysis is not reasonably 

debatable. See Donnell, 2022 WL 622001, at *10. 

2

 We need not address the district court’s alternative conclusion on the merits 

because the procedural bar is not reasonably debatable. See Davis v. Roberts, 425 F.3d 

830, 834 (10th Cir. 2005). Mr. Donnell does not challenge the district court’s decision to 

allow the state’s waiver defense despite failing to raise it in its pre-answer response. See 

Donnell, 2022 WL 622001, at *12. 

3

 We cite this and other unpublished dispositions only for their persuasive 

value. 10th Cir. R. 32.1.

parties to address its decision. Donnell, 2022 WL 622001, at *11. Defense counsel 

responded: “I’m not going to address the Court’s position as to the proposed plea bargain. 

The Court simply is not apparently willing to accept it now.” Id. The state appellate 

court concluded that defense counsel “effectively communicat[ed] that defendant did not 

need or want more explanation from the court,” and deemed the claim waived. Id. Based 

on this record, it is not reasonably debatable that defense counsel waived any opportunity 

to challenge the trial court’s lack of explanation for rejecting the plea agreement, and no 

showing has been made of cause and prejudice or a fundamental miscarriage of justice. 

See Coleman v. Thompson, 501 U.S. 722, 750 (1991). 

Finally, the district court’s assessment of Mr. Donnell’s fourth claim regarding the 

cumulative error doctrine is not reasonably debatable. “The cumulative-error analysis 

applies where there are two or more actual errors.” Cuesta-Rodriguez v. Carpenter, 916 

F.3d 885, 915 (10th Cir. 2019) (quoting Smith v. Duckworth, 824 F.3d 1233, 1255 (10th 

Cir. 2016)). Finding no accumulation of errors to analyze, the cumulative error doctrine 

does not apply. 

We GRANT the motion to proceed IFP, but DENY a COA and DISMISS the 

appeal.
