Appeal from the United States District Court for the Middle District of Florida D.C. Docket No. 2:23-cr-00106-SPC-KCD-1

Before NEWSOM, GRANT, and LUCK, Circuit Judges. PER CURIAM:

In this consolidated appeal, Jimmy Diggs appeals his sentences for two counts of possession of a firearm as a convicted felon, entered in separate cases. See 18 U.S.C. § 922(g)(1). According to Diggs, the district court erred by enhancing his sentence under the Armed Career Criminal Act because his prior Florida cocaine convictions were not serious drug offenses since Florida’s definition of cocaine was categorically broader than the federal definition . Below, the issue he raised was that Florida’s cocaine definition included ioflupane while the federal definition did not. Now, the issue he raises is that Florida’s definition of cocaine included “any stereoisomer of cocaine,” while the federal definition only included “optical and geometric isomers” of cocaine. Reviewing his unpreserved isomer issue for plain error, we conclude that the district court did not plainly err in treating Diggs’s prior convictions as serious drug offenses under the Act.

24-10232 Opinion of the Court 3

FACTUAL BACKGROUND AND PROCEDURAL HISTORY Diggs pleaded guilty in two separate cases to possessing firearms as a convicted felon. Diggs moved for a single sentencing hearing, which the district court granted.

The probation office prepared a presentence report for both cases, recommending that Diggs be sentenced as an armed career criminal. According to the report, Diggs had at least three prior convictions for violent felonies or serious drug offenses committed on different occasions: (1) a 1990 Florida conviction for the sale, manufacture, or possession with intent to sell cocaine; (2) a 1993 armed robbery; and (3) a 2011 Florida conviction for the sale of cocaine within 1,000 feet of a specified area.

Diggs objected to the designation as an armed career criminal , asserting that his drug convictions were not serious drug offenses under the Act because Florida’s definition of cocaine was categorically broader than the federal definition. Specifically, he contended that, at the time he committed the predicate offenses, Florida’s drug schedules included ioflupane while the federal drug schedules did not. Compare Fla. Stat. § 893.03(2)(a)(4) (1990); id. § 893.03(2)(a)(4) (2011) to 21 U.S.C. § 812 Sched. II at (a)(4) (1990); id. § 812 Sched. II at (a)(4) (2011). The district court overruled Diggs’s objection because it was foreclosed by our decision in United States v. Jackson, 55 F.4th 846 (11th Cir. 2022), aff’d sub nom., Brown v. United States, 602 U.S. 101 (2024). Adopting the presentence report, the district court sentenced Diggs under the Act as an armed career criminal.

4 Opinion of the Court 24-10232

Diggs now appeals his sentence. This time, however, he contends that Florida’s cocaine definition was overbroad because it encompassed “stereoisomers,” while the federal definition included only “optical and geometric isomers.” Compare Fla. Stat. § 893.03(2)(a)(4) (1990); id. § 893.03(2)(a)(4) (2011) to 21 U.S.C. § 812 Sched. II at (a)(4) (1990); id. § 812 Sched. II at (a)(4) (2011). Reviewing the issue for plain error, we affirm the district court’s sentence.

STANDARD OF REVIEW

We review unpreserved challenges for plain error. United States v. Laines, 69 F.4th 1221, 1229 (11th Cir. 2023).

DISCUSSION

The Armed Career Criminal Act requires any person who violates 18 U.S.C. section 922(g) to serve a mandatory minimum imprisonment sentence of fifteen years when the defendant is an “armed career criminal,” meaning he has three prior convictions for violent felonies or serious drug offenses committed on separate occasions. 18 U.S.C. § 924(e)(1). A “prior state drug conviction constitutes” a predicate conviction under the Act “if the drugs on the federal and state schedules matched when the state drug offense was committed.” Brown, 602 U.S. at 119.

In making this determination, we apply a categorical approach and consider the statutory definition of the state offense rather than the facts of the crime itself. Jackson, 55 F.4th at 850. A state conviction qualifies as a predicate under the Act only if the state statute under which the conviction occurred defines the

24-10232 Opinion of the Court 5

offense in the same way as, or more narrowly than, the federal definition of a “serious drug offense.” Id. That is, “all the controlled substances covered by the state law must also be controlled substances under federal law.” Laines, 69 F.4th at 1233.

Here, Diggs contends that his Florida convictions do not qualify as serious drug offenses because Florida’s cocaine definition was broader than the federal definition. Specifically, Diggs asserts that Florida’s definition encompassed “stereoisomers,” while the federal definition included only “optical and geometric isomers.” Compare Fla. Stat. § 893.03(2)(a)(4) (1990); id. § 893.03(2)(a)(4) (2011) to 21 U.S.C. § 812 Sched. II at (a)(4) (1990); id. § 812 Sched. II at (a)(4) (2011). But, as Diggs concedes, in the district court, he focused only on Florida’s inclusion of ioflupane in its drug schedules and he did not mention isomers. Thus, as we will explain, we must review the isomer issue for plain error. And the district court did not plainly err.

I.

Because both his issues relate to whether Florida’s cocaine definition was overbroad, Diggs contends that he preserved the isomer issue by raising the ioflupane issue in the district court. We disagree.

“To preserve an issue for appeal, one must raise an objection that is sufficient to apprise” the district court and the opposing party of “the particular grounds upon which appellate relief will later be sought.” United States v. Straub, 508 F.3d 1003, 1011 (11th Cir. 2007) (quotation marks omitted). “[T]he district court is not

expected to read minds or independently conceive of every possible argument a party might raise in support of an objection.” Id. Instead, “[i]t is a defendant’s—or his counsel’s—burden to articulate the specific nature of his objection . . . so that the district court may reasonably have an opportunity to consider it.” United States v. Zinn, 321 F.3d 1084, 1090 (11th Cir. 2003); see also United States v. Corbett, 921 F.3d 1032, 1043 (2019) (explaining that a defendant must raise “specific factual and legal argumentation at every stage of sentencing proceedings”). Thus, a defendant fails to preserve a challenge to his sentence when his objections before the district court are “substantively different” from what he raises on appeal. See United States v. Ramirez-Flores, 743 F.3d 816, 821 (11th Cir. 2014).
