The trial court denied the defendant's request for additional presentence custody credits, directing the probation department to calculate them instead. The Court of Appeal reversed, holding that the sentencing court has a duty to calculate and award these credits itself.

The appellate court held that the trial court erred by refusing to calculate the credits itself, citing the duty of the sentencing court to recalculate credits upon remand.

Authorities

  • relied: People v. Sek (2022) 74 Cal.App.5th 657 — When a sentence is modified on remand, the sentencing court must recalculate and credit all actual time served and calculate conduct credits for the period before the original sentencing hearing.
  • relied: People v. Buckhalter (2001) 26 Cal.4th 20 — The sentencing court must recalculate and credit against the modified sentence all actual time the defendant has already served.
  • relied: People v. Montalvo (1982) 128 Cal.App.3d 57 — It is the duty of the sentencing court itself to calculate and award presentence credits, though it may seek input from probation or CDCR.

The appellate opinion: sound — The opinion correctly applies established California law (Buckhalter, Sek, Montalvo) to hold that the sentencing court, not the probation department, bears the duty to calculate and award presentence credits upon remand. The reasoning is concise and directly addresses the trial court's procedural error.

A model's reading — claude-fable-5-1, prompt v1, 2026-10-13T04:29Z · confidence low

After a remand for resentencing, the Riverside County Superior Court declined to recalculate and award Aaron Gurtner's custody credits for the time served between his original sentencing and resentencing, instead ordering the probation department to calculate the credits and forward them to CDCR, and it denied his later motion on the same basis. The Court of Appeal accepted the People's concession of error, reversed the order, and remanded with directions for the trial court itself to calculate and award the additional credits, issue an amended abstract of judgment, and forward it to CDCR.

“We agree with the parties that the trial court erred by refusing to calculate and award these credits itself.”
unclearerror (law misapplied)agree with court
Under Buckhalter and section 2900.1, when a sentence is modified on appellate remand the sentencing court must itself recalculate and credit all actual time served, before and after the original commitment, and Montalvo confirms that this duty cannot be delegated to probation or CDCR. The trial court's order delegating the calculation entirely to probation was contrary to this settled law, and the People conceded as much. The opinion correctly distinguishes, via Sek, that CDCR rather than the court calculates conduct credit for the post-sentencing prison period.

Authorities

  • relied: People v. Buckhalter (2001) 26 Cal.4th 20 — When a prison term in progress is modified after an appellate remand, the sentencing court must recalculate and credit all actual time served, in jail or prison, before or after the original commitment; CDCR, not the court, determines conduct credit for post-sentencing prison time.
  • relied: People v. Sek (2022) 74 Cal.App.5th 657 — On resentencing after remand the trial court must credit all actual time served and calculate conduct credits for the presentence period, while the custodial agency calculates conduct credit for the period after original sentencing.
  • relied: People v. Montalvo (1982) 128 Cal.App.3d 57 — It is the sentencing court's own duty to calculate and award presentence custody credits, even if it may seek input from probation or corrections officials.

The appellate opinion: sound — The opinion correctly applies Buckhalter, section 2900.1, Sek, and Montalvo to hold that the sentencing court may not delegate the recalculation of actual custody credits after an appellate remand, and the People's concession confirms the result. The only blemish is a citation typo giving Sek a 2002 date although a volume 74 Cal.App.5th decision is from 2022, and the opinion does not state a standard of review, which is unneeded given the purely legal question.

COURT OF APPEAL, FOURTH APPELLATE DISTRICT

DIVISION ONE

STATE OF CALIFORNIA

THE PEOPLE, D084937

Plaintiff and Respondent, v. (Super. Ct. No. RIF2105199)

AARON ERWIN GURTNER,

Defendant and Appellant.

APPEAL from an order of the Superior Court of Riverside County, Eric A. Keen, Judge. Reversed and remanded with directions. Robert L.S. Angres, under appointment by the Court of Appeal, for Defendant and Appellant. Rob Bonta, Attorney General, Lance E. Winters, Chief Assistant Attorney General, Charles C. Ragland, Assistant Attorney General, A. Natasha Cortina and Elizabeth M. Renner, Deputy Attorneys General, for Plaintiff and Respondent. MEMORANDUM OPINION Aaron Erwin Gurtner appeals from an order denying his request for custody credits for the time served from his original sentencing hearing and a resentencing hearing after a prior appeal. The People concede that Gurtner is entitled to these custody credits and the trial court erred by denying his request and instead directing the probation department to provide the updated credits information to the California Department of Corrections and Rehabilitation (CDCR). We accept the People’s concession and remand the matter to the trial court to calculate and award these credits and amend the abstract of judgement accordingly. A jury found Gurtner guilty of two counts of attempted murder (Pen.

Code,1 §§ 187, 664) and found true the enhancements on each count for personally and intentionally discharging a firearm (§ 12022.53, subd. (c)). The court sentenced him to 14 years to life, plus 20 years. At the original sentencing, the court awarded Gurtner 469 days of credit consisting of 408 days of actual time and 61 days of conduct credit. On direct appeal, we found that the concurrent enhancement attached to count two was unauthorized. (People v. Gurtner (May 9, 2024, D083312) [nonpub. opn.].) We therefore reversed and remanded for resentencing. At the resentencing, the trial court did not award any additional credit for the time Gurtner served after the original sentencing. Instead, the court stated that the probation department could determine the additional credits and forward the information to CDCR. On January 23, 2025, Gurtner’s counsel wrote an informal letter to the superior court, informing it that Gurtner’s presentence confinement credit had not been updated and requesting that the additional credits be awarded 1 All further statutory references are to the Penal Code. 2 and the abstract of judgment amended. The court issued a minute order treating the letter as a motion and denying the motion as follows: “The court previously ordered for probation to calculate credits and forward them to the Department of Corrections. [¶] That order will remain. [¶] Credits to be calculated by Probation.” This appeal followed. We agree with the parties that the trial court erred by refusing to calculate and award these credits itself. “ ‘[W]hen a prison term already in progress is modified as the result of an appellate sentence remand, the sentencing court must recalculate and credit against the modified sentence all actual time the defendant has already served, whether in jail or prison, and whether before or since he was originally committed and delivered to prison custody.’ ” (People v. Sek (2002) 74 Cal.App.5th 657, 673, quoting People v. Buckhalter (2001) 26 Cal.4th 20, 29; see § 2900.1.) “The court must also calculate conduct credits for the period before the original sentencing hearing. [Citation.] The agency to which the defendant is committed—in this case the Department of Corrections and Rehabilitation—calculates and applies conduct credit for time following the original sentencing hearing.” (People v. Sek, at p. 673.) Although the court may seek input from probation or CDCR, it is the duty of the sentencing court itself to calculate and award presentence credits. (People v. Montalvo (1982) 128 Cal.App.3d 57, 62–63.) We therefore conclude that the trial court must calculate and award these additional presentence credits and issue an amended abstract of judgement. DISPOSITION The order denying Gurtner’s request for additional presentence credits is reversed. The matter is remanded to the trial court to calculate and award the additional presentence credits, issue an amended abstract of judgment, 3 and forward a certified copy of the amended abstract to the Department of Corrections and Rehabilitation.
