In Sarabia v. Warden FCI Sandstone, Judge Tunheim denied Felipe Cabrera Sarabia's petition challenging how the Bureau of Prisons calculated his good conduct time credits.

Who this affects

Federal prisoners who served time in foreign custody before being sentenced in U.S. courts and who dispute how the Bureau of Prisons calculates their good conduct time credits under the First Step Act. This opinion also affects prisoners whose sentencing transcripts and written judgments state different sentence lengths.

What happened

In Sarabia v. Warden FCI Sandstone (Civil No. 25-705), Felipe Cabrera Sarabia, a federal prisoner at FCI Sandstone in Minnesota, filed a petition challenging how the Bureau of Prisons (BOP) calculated his good conduct time (GCT) credits under the First Step Act of 2018. Sarabia argued that the BOP should base his GCT credits on a 230-month sentence rather than the 128-month sentence shown in his amended judgment. He contended this error resulted in him receiving 575 days of GCT credits instead of the 1,035 days he believed he was owed.

The background is somewhat complicated: a federal sentencing court in Illinois initially announced a 230-month sentence for Sarabia's drug trafficking conviction, but then agreed — at the request of Sarabia's own attorney — to reduce the stated sentence to 128 months to account for approximately 102 months Sarabia had already served in Mexico on a conviction that was later overturned. The final written judgment reflected the 128-month term. The BOP then calculated Sarabia's GCT credits based on that 128-month sentence. Sarabia argued the 230-month figure was the real sentence, and the 128-month figure was merely a credit calculation, not the true length of his sentence.

Judge John R. Tunheim overruled Sarabia's objections to the Magistrate Judge's Report and Recommendation, adopted that recommendation, denied the petition, and dismissed the action with prejudice (meaning the same claim cannot be refiled). The court concluded that the 'sentence imposed' for purposes of calculating GCT credits is best understood as the 'term of imprisonment,' which the written judgment clearly stated as 128 months. The court found the written judgment was consistent with and clarified the sentencing court's intent, so the BOP properly calculated Sarabia's GCT credits based on that term.

Background

Felipe Cabrera Sarabia is a federal prisoner serving his sentence at Federal Correctional Institution – Sandstone in Minnesota. He was indicted in the Northern District of Illinois in 2009 on drug trafficking charges. Before he could be tried in the United States, Mexican authorities arrested him in December 2011 on charges arising from the same underlying conduct. He remained detained in Mexico until June 2020, when his Mexican conviction was overturned by the Mexican Supreme Court and he was extradited to the United States.

In 2023, Sarabia pleaded guilty in the Northern District of Illinois to distributing one kilogram or more of a mixture or substance containing heroin, in violation of 21 U.S.C. § 841(a)(1). The sentencing court calculated a Guidelines range of 292 to 365 months. During the sentencing hearing, the court initially announced a sentence of 230 months. However, the government then noted that, by operation of statute, the BOP would need to reduce Sarabia's sentence to account for the approximately 102 months he had already served in Mexico on his overturned conviction. The government offered two options: leave the judgment at 230 months and let the BOP apply the statutory reduction, or state in the judgment that the sentence was 128 months, reflecting that the 102 months of Mexican custody had already been factored in. Sarabia's counsel requested the latter, and without objection, the sentencing court agreed. The final amended Judgment and Conviction (J&C) stated that Sarabia was committed to the BOP for 'a total term of: 128 months,' with a notation that the sentence 'includes credit for 102 months of custody already served in Mexico.'

The Dispute Over Good Conduct Time Credits

Under the First Step Act of 2018, eligible federal prisoners may earn good conduct time (GCT) credits of up to 54 days for each year of 'the prisoner's sentence imposed by the court.' 18 U.S.C. § 3624(b)(1). The BOP calculated Sarabia's maximum GCT credits based on the 128-month sentence in the amended judgment: 540 days for 10 full years plus 35 days prorated for the remaining 8 months, totaling 575 days. Sarabia contested this, arguing that the true 'sentence imposed' was 230 months — and that he was therefore entitled to 1,035 days of GCT credits.

After exhausting administrative remedies within the BOP, Sarabia filed a petition for a writ of habeas corpus (a court order challenging the legality of his confinement) under 28 U.S.C. § 2241, asking the court to direct the BOP to recalculate his GCT credits based on the 230-month figure.

Magistrate Judge's Report and Recommendation

Magistrate Judge John F. Docherty issued a Report and Recommendation (R&R) recommending that the petition be denied, concluding that Sarabia was sentenced to 128 months — not 230 months — and that the BOP had properly calculated GCT credits on that basis. Sarabia filed timely objections, triggering de novo (fresh, independent) review by District Judge Tunheim.

The Court's Analysis

Standard of Review

Because Sarabia is a pro se litigant (representing himself without an attorney), the court applied a liberal construction to his submissions, consistent with the Eighth Circuit's instruction to liberally construe general and conclusory pro se objections and conduct de novo review of all alleged errors.

The Legal Question: What Was the 'Sentence Imposed'?

The court framed the sole legal question as: was the 'sentence imposed by the court' 128 months or 230 months for purposes of 18 U.S.C. § 3624(b)(1)?

Under Eighth Circuit precedent, the oral pronouncement by a sentencing court is ordinarily considered the operative judgment. United States v. Tramp, 30 F.3d 1035, 1037 (8th Cir. 1994). However, when a written judgment is consistent with and simply clarifies the court's discernible intent in the oral pronouncement, there is no conflict and the written judgment may be treated as operative. United States v. Mays, 993 F.3d 607, 622 (8th Cir. 2021).

The court acknowledged that 'neither the transcript nor the J&C is a model of clarity.' Nevertheless, it concluded that the 'sentence imposed' is most properly understood as the 'term of imprisonment.' The court cited the GCT statute's own language, 18 U.S.C. § 3624(g)(5) (referring to 'the term of imprisonment to which the prisoner was sentenced'), and a BOP regulation, 28 C.F.R. § 523.44(a)(1) (referencing prisoners '[s]entenced to a term of imprisonment under the U.S. Code'). The written J&C, which stated the term of imprisonment as 128 months, was found to clarify what had been ambiguous in the sentencing transcript, and was consistent with the sentencing court's discernible intent after the 102-month credit was raised.

The BOP's Calculation

Given a 128-month sentence (10 years and 8 months), the court found the BOP correctly calculated Sarabia's GCT credits: 54 days × 10 full years = 540 days, plus 35 days prorated for the final 8 months, totaling 575 days. The court noted that Sarabia himself did not dispute the mathematical accuracy of the calculation assuming a 128-month sentence — his dispute was solely about which sentence length should be used as the basis.

Disposition

Judge Tunheim overruled Sarabia's objections, adopted the Magistrate Judge's R&R, denied the petition for a writ of habeas corpus, and dismissed the action with prejudice. Dismissal with prejudice means Sarabia cannot refile the same claim in federal court.
