2 Opinion of the Court 22-14127

Before ROSENBAUM, GRANT, and ANDERSON, Circuit Judges.

PER CURIAM:

After pleading guilty, Alphonso Richardson appeals his sentence of 235 months of imprisonment for unlawful possession of a 

firearm and ammunition. At sentencing, the district court found 

that Richardson qualified for the fifteen-year enhanced minimum 

penalty under the Armed Career Criminal Act (“ACCA”), see 18 

U.S.C. § 924(e), because he had at least three prior convictions for 

a violent felony or a serious drug offense. In doing so, the court 

relied on six prior convictions, all in Florida: three separate convictions for sale of cocaine; possession of cocaine with intent to sell; 

resisting an officer with violence; and sale, manufacture, delivery, 

or possession with intent to sell a controlled substance. On appeal, 

Richardson contends that all but one of his prior drug convictions 

do not qualify as ACCA predicate offenses. Because his arguments 

are foreclosed by recent binding precedent, we affirm. 

I.

We review de novo whether a conviction qualifies as a serious drug offense under the ACCA. United States v. White, 837 F.3d 

1225, 1228 (11th Cir. 2016). “In conducting our review, we are 

bound to follow a prior binding precedent unless and until it is 

overruled by this court en banc or by the Supreme Court.” Id.

(quotation marks omitted). 

The ACCA mandates a fifteen-year minimum sentence 

when a defendant convicted of unlawfully possessing a firearm has

22-14127 Opinion of the Court 3

three prior convictions for a violent felony or serious drug offense. 

See 18 U.S.C. § 924(e)(1). The statute defines a “serious drug offense” as an offense “involving manufacturing, distributing, or possessing with intent to manufacture or distribute, a controlled substance (as defined in section 102 of the Controlled Substances Act 

(21 U.S.C. § 802)).” Id. § 924(e)(2)(A)(ii).

To determine whether a state conviction qualifies as a predicate offense under the ACCA, we follow what is described as a 

“categorical approach.” White, 837 F.3d at 1229. Under this approach, we consider only the statutory definition of the offense, rather than the particular facts of the defendant’s crime. Id.

II.

Richardson argues that he lacks the necessary qualifying 

ACCA predicate convictions for two reasons. First, he says that his 

pre-2015 Florida cocaine offenses do not categorically qualify as 

“serious drug offenses” because he could have been convicted for 

substances that were not federally controlled when he committed 

the federal gun crime. And second, he maintains that his convictions for sale of cocaine do not qualify as serious drug offenses because the proscribed conduct does not necessarily entail the “distribution” of a controlled substance.

A.

Richardson contends that his pre-2015 cocaine-related convictions would not qualify as serious drug offenses based on the 

since-vacated decision in United States v. Jackson (“Jackson I”), 36 

F.4th 1294, 1302 (11th Cir. 2022). In Jackson I, we held that the 

USCA11 Case: 22-14127 Document: 26-1 Date Filed: 08/07/2024 Page: 3 of 6
4 Opinion of the Court 22-14127

ACCA’s definition of “serious drug offense” incorporated the version of the federal drug schedules in effect when the defendant committed the federal gun offense for which he is being sentenced. Id. at 1297, 

1300. Applying that rule, along with the categorical approach, we 

concluded that the defendant’s Florida cocaine-related convictions 

did not qualify as serious drug offenses because he could have been 

convicted for the cocaine-derivative ioflupane, which was not a 

controlled substance under federal law when the gun offense was 

committed. Id. at 1304.

As Richardson concedes, however, we sua sponte vacated 

Jackson I and issued a superseding opinion holding that the defendant’s Florida cocaine-related convictions qualified as serious drug 

offenses under the ACCA. Jackson II, 55 F.4th at 861–62. We explained that Supreme Court precedent required us to hold that the 

ACCA’s definition of a serious drug offense incorporates the version of the federal controlled substances schedules in effect when 

the defendant was convicted of the prior state drug offense. Id. at 854. In 

other words, whether ACCA applies “turn[s] on the law in effect 

when the defendant’s prior convictions occurred,” not at the time 

of the federal offense. Id. at 859. Because both the state and federal 

drug schedules included ioflupane at the time of the defendant’s

prior convictions, we found that they qualified as “serious drug offenses.” Id. at 861–62.

The Supreme Court subsequently affirmed our decision in 

Jackson II. Brown v. United States, 144 S. Ct. 1195 (2024). The Court 

held that “a prior state drug conviction constitutes an ACCA 

USCA11 Case: 22-14127 Document: 26-1 Date Filed: 08/07/2024 Page: 4 of 6
22-14127 Opinion of the Court 5

predicate if the drugs on the federal and state schedules matched 

when the state drug offense was committed,” even if the schedules 

were later amended. Id. at 1208, 1210. 

Here, Richardson’s pre-2015 cocaine convictions are not 

overbroad. As in Jackson II, Richardson’s convictions occurred 

when both the state and federal drug schedules included ioflupane. 

See 55 F.4th at 861–62 & 851 n.3. In other words, “the drugs on the 

federal and state schedules matched when the state drug offense[s]

w[ere] committed.” Brown, 144 S. Ct. at 1207. Thus, Richardson’s 

challenge is foreclosed. 

B.

In the alternative, Richardson contends that sale of cocaine

under Florida law does not categorically qualify as a serious drug 

offense because it includes the mere attempted transfer of cocaine, 

and, therefore, criminalizes a broader range of conduct than encompassed by the ACCA’s definition. 

While Richardson’s appeal was pending in this Court, we rejected an identical challenge in United States v. Penn and held that 

Florida convictions for sale of cocaine categorically qualify as serious drug offenses for purposes of the ACCA. 63 F.4th 1305, 1310–

17 (11th Cir. 2023). In so holding, we rejected the identical arguments that Richardson makes here. See id. at 1316–17. 

Specifically, we rejected the argument that the sale of cocaine under Florida law—which includes attempted transfers—

does not satisfy the requirements set forth in Shular v. United States, 

589 U.S. 154 (2020), because the attempted transfer of a controlled 

USCA11 Case: 22-14127 Document: 26-1 Date Filed: 08/07/2024 Page: 5 of 6
6 Opinion of the Court 22-14127

substance does not “necessarily entail” the conduct of distributing. 

Penn, 63 F.4th at 1316. We reasoned that “distribution” under the 

ACCA’s definition included attempted transfers, id. at 1312–13, so 

there was “a perfect match between what the state offense proscribes and what is ‘distributing,’” id. at 1316. As a result, we said, 

“Shular’s reading of ‘involving’ as ‘necessarily entails’ has no bearing on this case.” Id. at 1316. 

Likewise, we also rejected the argument that sale of cocaine 

under Florida law could not be a serious drug offense because an 

attempted transfer was an inchoate offense. See id. at 1316–17; cf. 

United States v. Dupree, 57 F.4th 1269, 1277–79 (11th Cir. 2023) (en 

banc) (interpreting similar language to that of § 924(e)(2)(A)(ii) in 

U.S.S.G. § 4B1.2 to exclude inchoate offenses). We reasoned that 

“the attempted transfer of drugs forms part of the completed saleof-drugs offense under Florida law,” and so was “not an inchoate

offense under Florida law.” Penn, 63 F.4th at 1317. 

We are bound by our decision in Penn, which squarely forecloses Richardson’s arguments. See White, 837 F.3d at 1229. Richardson does not suggest otherwise, even if he believes Penn was 

wrongly decided. 

In sum, we affirm Richardson’s sentence. 

AFFIRMED.
