Before SYKES, Chief Judge, and BRENNAN and SCUDDER, Circuit Judges. 

SCUDDER, Circuit Judge. Seven years into his 15-year sentence for heroin dealing, Tony Brock sought early discharge 

∗We have agreed to decide this case without oral argument because 

the brief and record adequately present the facts and legal arguments, and 

oral argument would not significantly aid the court. See FED. R. APP.

2 No. 22-1148 

under the compassionate release statute, 18 U.S.C. 

§ 3582(c)(1)(A). Receiving that relief depended on Brock first 

identifying a legally cognizable “extraordinary and compelling” reason for ending his sentence early and then convincing the district court the outcome was further justified by an 

application of the 18 U.S.C. § 3553(a) factors. Brock approached the first of those requirements by contending that 

our recent decision in United States v. Ruth, 966 F.3d 642 

(7th Cir. 2020), changed the law—by reinterpreting a definition in the federal drug statutes—in a way that amounted to

an extraordinary and compelling ground to consider a lower 

sentence. The district court denied relief, relying on United 

States v. Thacker, 4 F.4th 569 (7th Cir. 2021), to conclude that 

the compassionate release statute could not be used as a path 

to a sentence reduction based on a position available to defendants during plea negotiations or trial, direct appeal, or in 

a post-conviction motion under 28 U.S.C. § 2255 challenging

a sentence. We agree and affirm. 

I 

A 

In October 2013 a federal grand jury in the Central District 

of Illinois indicted Brock for possessing heroin with intent to 

distribute (Count One) and a related conspiracy charge 

(Count Two). The government then filed a notice under 21 

U.S.C. § 851 informing Brock of its intent to enhance his sentence based on a 2005 conviction for possessing with intent to 

distribute cocaine in Illinois. The § 851 notice, commonly 

called a prior felony information, had the effect of increasing 

the maximum sentence on Count One from 20 to 30 years. It 

likewise increased the sentencing range on Count Two from 5 

to 40 years to 10 years to life. 
No. 22-1148 3

Brock pled guilty to both counts under an agreement expressly waiving his rights to appeal or collaterally attack his 

sentence, subject to exceptions not relevant here. The district 

court sentenced Brock to 180 months (15 years). Adhering to 

the waiver in his plea agreement, Brock did not appeal. But 

he did file a series of post-conviction challenges through requests for relief under 28 U.S.C. §§ 2241 and 2255. None 

proved successful. 

B 

In 2020 Brock turned to § 3582(c)(1)(A) and asked the district court for early release. Pointing to our decision earlier 

that year in United States v. Ruth, he argued that his 2005 cocaine conviction was no longer a proper predicate for the

§ 851 sentencing enhancement because the Illinois statute under which he was convicted covers isomers of cocaine omitted 

from Congress’s definition of cocaine in Title 21 of the U.S. 

Code. To Brock, then, Ruth reflected an “extraordinary and 

compelling” reason—a favorable change in case law affecting 

his sentence—that made him eligible for a sentence reduction 

under the compassionate release statute. 

The district court disagreed and summarily denied 

Brock’s motion. Citing our decision in Thacker, the district 

court saw Brock’s alleged sentencing error as part of a class of 

arguments defendants could pursue on direct appeal or in a 

post-conviction motion under § 2255, but not under the compassionate release statute. Put another way, Brock’s Ruthbased challenge to his sentence did not constitute an “extraordinary and compelling” reason for early release. 

Brock now appeals. 
4 No. 22-1148 

II

Understandably, Brock would like a lower sentence. But 

the reasoning underpinning our decisions in Thacker and 

United States v. Martin, 21 F.4th 944 (7th Cir. 2021), forecloses 

his use of the compassionate release statute to pursue that end 

based on what he sees as the change in law announced in 

Ruth. And although that principle fully resolves this case, we 

add that allowing Brock to pursue the relief he seeks under 

§ 3582(c)(1)(A) would license an end run around the appeal 

and collateral attack waivers he agreed to in his plea agreement. 

A 

In Thacker we emphasized that the authority in the compassionate release statute “only goes so far” and “cannot be 

used to effect a sentencing reduction at odds with Congress’s 

express determination embodied in” other statutes. 4 F.4th at 

574. Those observations led us to hold that § 3582(c)(1)(A) 

“does not permit—without a district court finding some independent ‘extraordinary or compelling’ reason—the reduction 

of sentences lawfully imposed before the effective date of the 

First Step Act’s amendment to [18 U.S.C.] § 924(c),” an amendment which, by its terms, applies only prospectively. Id. at 

575. 

Martin followed, complementing Thacker by holding that 

the compassionate release statute cannot be used to challenge 

a sentence on grounds the defendant could have advanced on 

direct appeal. See 21 F.4th at 946. Any other conclusion, we 

explained, would permit a defendant to “circumvent the normal process for challenging potential sentencing errors, either 

through the direct appeal process or collaterally through a 28 
No. 22-1148 5

U.S.C. § 2255 motion”—a concern we first sounded in Thacker. 

Id. (citing Thacker, 4 F.4th at 574). 

As the district court recognized, Brock’s compassionate release motion runs headlong into this principle. He seeks early 

release under § 3582(c)(1)(A) based on an argument generally 

available to litigants on direct appeal or (more properly) in 

plea negotiations and at the time of the original sentencing. 

Nothing prevented Brock and his counsel from arguing that 

his 2005 conviction came under a provision of Illinois law that 

was too broad to enhance his federal sentence. That we did 

not expressly adopt this precise position until Ruth does not 

change the analysis. Our decision in Ruth—even if viewed as 

announcing new law or a new interpretation of an existing 

statutory provision—cannot alone constitute an “extraordinary and compelling” reason authorizing a reduced sentence 

under § 3582(c)(1)(A). 

That conclusion resolves this case. But recognize, too, the 

potential consequence of a contrary conclusion on these facts, 

where Brock chose to plead guilty pursuant to an agreement 

in which he expressly waived his rights to directly appeal or 

collaterally attack his conviction or sentence. “[O]ne major 

purpose of an express waiver,” we have emphasized, “is to 

account in advance for unpredicted future developments in 

the law.” Oliver v. United States, 951 F.3d 841, 845 (7th Cir. 

2020). So, in entering the plea agreement, Brock “assume[d] 

the risk of future changes in circumstances in light of which 

one’s bargain may prove to have been a bad one.” United 

States v. Bownes, 405 F.3d 634, 636 (7th Cir. 2005). Subsequent 

developments in the law may have proven favorable for 

Brock. But he chose to run that risk, and the compassionate 
6 No. 22-1148 

release statute does not provide a safety valve allowing him 

to renege on his agreement with the government. 

B 

Brock urges a different conclusion, directing our attention 

to United States v. Liscano, No. 02 CR 719-16, 2021 WL 4413320 

(N.D. Ill. Sept. 27, 2021). In Liscano, the district court concluded that the government’s “admission that the [defendant’s] offenses no longer support a life sentence” because of 

subsequent developments in the law could constitute an extraordinary and compelling reason for purposes of 

§ 3582(c)(1)(A) sentencing relief. Id. at *8. The district court 

saw the limitations recognized in Thacker as having no application where the change in law animating a compassionate 

release motion comes not from Congress, but from decisions 

by courts. See id. at *7 n.4. 

We cannot agree. Judicial decisions, whether characterized as announcing new law or otherwise, cannot alone 

amount to an extraordinary and compelling circumstance allowing for a sentence reduction. To permit otherwise would 

allow § 3582(c)(1)(A) to serve as an alternative to a direct appeal or a properly filed post-conviction motion under 28 

U.S.C. § 2255. We rejected that view in Thacker and Martin and 

do so again here. 

We have considered Brock’s other arguments, but none 

has merit. 

For these reasons, we AFFIRM.
