BERNER, Circuit Judge:

Robert Gary Moore was tried in Maryland state court on two criminal counts:

possession of cocaine and possession of cocaine with intent to distribute. On the second

day of a three-day trial, the State introduced a previously undisclosed report, which

purported to describe the chain of custody of a plastic bag containing a substance that the

state relied upon to prove Moore possessed cocaine. The newly disclosed report could have

been used to cast doubt on whether the State had tested the contents of the plastic bag, thus

potentially undermining the sole evidence upon which the State relied to prove an essential

element of its case. The jury found Moore guilty of both counts.

After unsuccessfully pursuing relief in Maryland state court, Moore filed a petition

for a writ of habeas corpus in federal district court. He argued first that the State’s belated

disclosure of the chain-of-custody report violated his right to due process as required under

Brady v. Maryland. 373 U.S. 83 (1963). Second, Moore argued that his trial counsel had

been ineffective by failing to object to the belated disclosure or introduction of the chain-

of-custody report. Although the district court denied habeas relief on Moore’s claim of

ineffective assistance of counsel, it ruled that Moore was entitled to habeas relief on his

Brady claim. The district court then ordered Moore’s conviction vacated unless he was

retried within sixty days. The State timely appealed.

We agree with the district court that the Maryland state court unreasonably applied

clearly established federal law in its adjudication of Moore’s habeas petition. The State

committed a Brady violation and, therefore, habeas relief is warranted. Because federal

district courts lack authority to vacate state court convictions, however, we vacate the

underlying order and remand for the district court to issue a new order consistent with the

proper bounds of federal habeas relief.

I. Background

A. Factual History

We describe the facts of Moore’s underlying criminal case as adopted by

Maryland’s courts. 1 Two plainclothes police detectives traveled to a street in Baltimore

following a tip from a confidential informant alleging drug deals were taking place in the

area. There, the officers observed Moore and another individual standing in front of a

parked vehicle. One of the detectives announced that he was a police officer and displayed

his badge. Moore reached into his pocket, pulled out a plastic bag, dropped it on the ground,

and fled on foot. Following a chase, the detectives caught Moore and placed him under

arrest. The detectives then recovered the plastic bag and turned it over to the Baltimore

Police Department’s Evidence Control Unit (ECU) for safekeeping.

At trial, the State relied upon a laboratory analysis prepared by chemist Barry

Verger (the Verger Lab Analysis) attesting that the plastic bag contained 10.28 grams of

cocaine. Verger did not testify. The Verger Lab Analysis was the sole evidence introduced

by the State to meet its burden to prove that Moore possessed cocaine at the time of his

arrest.

We presume, as we must, that the “state court’s factual findings are correct unless 1

the petitioner rebuts those facts by clear and convincing evidence.” Nicholas v. Att’y Gen. of Maryland, 820 F.3d 124, 129 (4th Cir. 2016) (quoting 28 U.S.C. § 2254(e)(1)). Although Moore disputes certain facts as described, these disputes are not relevant to this appeal. 3 USCA4 Appeal: 24-6325 Doc: 44 Filed: 01/07/2026 Pg: 4 of 48

To establish the authenticity of the plastic bag and its contents, the State relied on

two different chain-of-custody reports that both purported to list every individual and entity

that had access to or took possession of the plastic bag while it was in police possession. 2

The Baltimore Police Department’s Laboratory Section maintained the first chain-of-

custody report (Laboratory Section report). The State disclosed this report to Moore prior

to the commencement of trial. The ECU maintained the second chain-of-custody report

(ECU report). The State disclosed the ECU report to Moore only on the second day of trial,

at the same time the State introduced the report into evidence. Notably, Verger’s name does

not appear in the ECU report. Had the State provided the ECU Report earlier, Moore’s

counsel may have capitalized on the discrepancy between the two reports to raise a number

of questions about the State’s case: did Verger test the correct bag? Was his analysis valid?

Was the Laboratory Section report doctored to add Verger’s name? Yet Moore’s trial

counsel raised no objection to the State’s belated disclosure of the ECU report or its

introduction into evidence. The timing of the disclosure lies at the heart of this appeal.

2 Chain-of-custody reports “establish that the item to be introduced [into evidence] is what it purports to be so as to convince the court that it is improbable that the original item had been exchanged with another or otherwise tampered with.” United States v. Robinson, 55 F.4th 390, 404–05 (4th Cir. 2022) (internal citations omitted).

B. Procedural History

As is true with most matters that come before this court on habeas review, the

procedural history of Moore’s case is complex, stretching almost fifteen years and winding

through multiple court proceedings. Following a three-day trial, a jury found Moore guilty

of simple possession and possession with intent to distribute cocaine. The state trial court

sentenced Moore to eight years’ incarceration. Moore appealed his conviction and the

Maryland intermediate court affirmed.

Moore then filed a petition for habeas relief in state court under the Maryland

Uniform Postconviction Procedure Act. Md. Code Crim. Proc. § 7-101 et seq. He argued
