In Sierra-Serrano v. Warden, FCI Sandstone, Judge Menendez dismissed a prisoner's challenge to his time-credit calculations because the claimed harm was too speculative for the court to have jurisdiction.
Federal prisoners who seek to challenge Bureau of Prisons calculations of sentencing credits — such as First Step Act time credits, good conduct time, or Second Chance Act credits — before a concrete and non-speculative injury has materialized. This ruling signals that such challenges may be dismissed for lack of jurisdiction when the petitioner's claimed release date depends on future events and discretionary BOP decisions.
What happened
In Edgar Manuel Sierra-Serrano v. Warden, FCI Sandstone (No. 25-cv-2274), a federal prisoner at FCI Sandstone filed a petition asking a federal court to review how the Bureau of Prisons was calculating his good-conduct time, First Step Act time credits, and Second Chance Act credits, and to declare a specific date by which he should be released to community supervision.
Magistrate Judge Elsa M. Bullard issued a Report and Recommendation concluding that the court lacked jurisdiction over the petition. Her reasoning was that the exact number of credits the petitioner might earn depends on future events that may or may not occur, and that any transfer to pre-release custody would still be entirely at the Bureau of Prisons' discretion. That combination made the petitioner's claimed injury too speculative — not concrete enough — for a federal court to hear the case. The petitioner did not file any objections to that recommendation.
Judge Katherine M. Menendez agreed with Magistrate Judge Bullard, finding no error in her analysis. The court adopted the Report and Recommendation and dismissed the petition without prejudice — meaning the petitioner is not permanently barred from filing again — solely because the court lacked jurisdiction, not because it evaluated whether the Bureau of Prisons had made any errors. The court also noted it cannot calculate the petitioner's First Step Act credits itself, as that is the Bureau of Prisons' responsibility.

Background
Petitioner Edgar Manuel Sierra-Serrano, a federal prisoner housed at FCI Sandstone, filed a petition for a writ of habeas corpus (a legal mechanism by which a prisoner challenges the legality of their imprisonment or conditions of confinement) on May 29, 2025. He alleged that the Federal Bureau of Prisons (BOP) was miscalculating three categories of sentencing credits: (1) good conduct time, (2) First Step Act (FSA) time credits — earned by participating in approved rehabilitation programs — and (3) Second Chance Act credits, which relate to pre-release placement. He argued these miscalculations were affecting his "Conditional Transition to Community" (CTC) date, which is the date he could potentially be transferred to pre-release community supervision. As relief, he asked the court to issue declarations fixing the maximum credits he could earn and establishing July 2, 2026 as his CTC date.
Magistrate Judge's Report and Recommendation
United States Magistrate Judge Elsa M. Bullard issued a Report and Recommendation (R&R) recommending that the petition be denied. The R&R concluded that the number of credits Sierra-Serrano is entitled to depends on events that have not yet occurred and may never occur. Furthermore, even if those credits were properly calculated, any transfer to pre-release custody would remain wholly discretionary on the part of the BOP — meaning no specific release date could be guaranteed by any court order. Judge Bullard concluded that these facts meant Sierra-Serrano had raised only a speculative risk of harm, which is insufficient to establish Article III standing (the constitutional requirement that a federal court can only hear cases involving real, concrete, and imminent injuries, not hypothetical or speculative ones). Petitioner did not file any objections to the R&R.
The Court's Analysis
Because no objections were filed, Judge Menendez reviewed the R&R under the "clear error" standard, which is a deferential standard that requires the court only to check for obvious mistakes rather than conduct an independent full review. Finding no clear error, the court adopted the R&R in full.
The court agreed that Sierra-Serrano's claimed injury was too speculative to establish federal court jurisdiction. The court cited TransUnion LLC v. Ramirez, 594 U.S. 413 (2021), for the proposition that a future risk of harm must be sufficiently concrete and not merely speculative to support Article III standing. Because the harm Sierra-Serrano alleged depended on future contingencies and on discretionary BOP decisions, he could not satisfy that threshold requirement.
Separately, the court addressed a letter Sierra-Serrano had sent to the Clerk's Office asking it to calculate his FSA credits. The court construed this letter as a motion and denied it, explaining that neither the court nor the Clerk's Office has the information needed to perform such a calculation, and that computing these credits is, in the first instance, the BOP's responsibility.
Disposition
The court:
- Accepted Magistrate Judge Bullard's Report and Recommendation;
- Denied the Petition for a Writ of Habeas Corpus; and
- Dismissed the matter without prejudice — meaning Sierra-Serrano is not permanently barred from reasserting his claims if and when a concrete, non-speculative injury materializes.
The dismissal was made solely on jurisdictional grounds (lack of Article III standing), and the court did not reach or decide the underlying merits of whether the BOP was actually miscalculating Sierra-Serrano's credits.
