William Maxwell is serving a 20-year federal sentence for racketeering. He did the programming, put in the work, and earned time credits under the First Step Act. Those credits are supposed to move a person out of a prison cell sooner, into a halfway house or home confinement. The Bureau of Prisons would not apply his credits that way. So Maxwell did what people in his position do. He filed a habeas petition himself, without a lawyer, arguing that he was being held in a more restrictive form of custody than the law allows.
The Fifth Circuit turned him away. Not because his credits were wrong, but because of the door he knocked on. Habeas, the court said, is not the proper vehicle for this kind of claim. He should have brought a civil rights lawsuit instead.
That ruling is now in front of the Supreme Court. The case is Maxwell v. Dinis, and it will be argued on Monday, November 2, 2026. The question is narrow and huge at the same time: can a federal prisoner use a habeas petition under 28 U.S.C. Section 2241 to challenge how First Step Act time credits are applied, when what he is asking for is a faster move to a halfway house or home confinement?
Here is the twist that tells you how shaky the lower ruling is. The government agrees with Maxwell. The Solicitor General told the Court the Fifth Circuit got it wrong and asked for the ruling to be vacated. When both sides agree, the Court appoints a lawyer to defend the losing side's position, and that is what happened here. An appointed attorney will argue for the Fifth Circuit's reasoning so the justices hear both sides tested.
Maxwell is not alone in this fight. The case has drawn support from the National Association of Criminal Defense Lawyers, FAMM, habeas scholars, and a bipartisan group of senators that includes Cory Booker, Dick Durbin, Chuck Grassley, and Mike Lee, the lawmakers who helped write the First Step Act itself.
Why should your family care about one man's petition? Because the door question decides real cases every week. If habeas is closed to credit disputes, a prisoner who is denied credits he earned has to find another way into court, and those other doors are slower, narrower, and easier to shut. If the Court says habeas is open, credit fights go back to being about the credits: were they earned, were they counted right, was the transfer wrongfully denied. That is where these cases belong.
Two things to keep straight. First, Maxwell has not won anything yet. The Court could side with the appointed lawyer and leave the Fifth Circuit's rule in place. Second, nothing changes on the ground until the Court decides, which usually means by the end of its term next summer. Keep your records. Keep using the BOP remedy process. And if your loved one's credits look wrong on paper, that paper trail is what any future filing will stand on.
Whatever happens on November 2, sit with what this case already proved. A petition one man wrote himself, from inside, is being argued at the highest court in the country, with the United States government on his side of the question. That does not happen often. It happened here because the filing was made.

Two days later, on Wednesday, November 4, the justices hear Guerrero v. Johnson, a case about second habeas petitions. Dexter Johnson is on Texas's death row. He wants to bring an intellectual disability claim under Atkins v. Virginia in a second petition, arguing that updated medical standards made his claim real for the first time. The question is whether a claim counts as based on a "new rule of constitutional law" that was "previously unavailable" when the rule itself was old but only later became usable. It is a state case, but the gatekeeping lesson reaches federal filers too. Second petitions live or die on narrow exceptions, and this case is about how narrow one of those exceptions really is.
What are First Step Act time credits?
They are credits a federal prisoner earns by completing recidivism reduction programs and productive activities. Earned credits can move a person into prerelease custody sooner, meaning a halfway house or home confinement, and in some cases toward earlier release.
Did Maxwell already win because the government agrees with him?
No. The government's agreement is a strong signal, but the Supreme Court still decides. The Court appointed a lawyer to defend the Fifth Circuit's ruling, and the justices will test both sides at argument on November 2, 2026.
What should my family do while the case is pending?
Keep the paper. Save program completion records, credit worksheets, and every BOP response. Keep using the administrative remedy process if a credit dispute comes up. Whatever the Court rules, the families who can prove what was earned and what was denied will be in the strongest position.
