“Proceedings” in Penal Code § 2900.5(b) Means a Single Criminal Case: No Automatic Cross-Case Pooling of Presentence Custody Credits

People v. Cofer (Cal. June 25, 2026) — Supreme Court of California

1. Introduction

In People v. Cofer, the California Supreme Court resolved a recurring sentencing-credit problem that arises when a defendant has multiple pending criminal cases, spends different amounts of time in custody on each, and then resolves them in a single negotiated disposition and is sentenced at a single hearing. The core question was whether Penal Code section 2900.5, subdivision (b) requires courts to “pool” presentence custody credits across multiple separately filed cases merely because they are sentenced together.

Parties: The People (plaintiff/respondent) and Christopher Lee Cofer (defendant/appellant).
Key issue: What does “custody … attributable to proceedings related to the same conduct” mean in section 2900.5(b), and does a single sentencing hearing transform multiple cases into the same “proceedings” for presentence credit purposes?

2. Summary of the Opinion

3. Case Background (What Happened)

Cofer had five separately filed cases (A–E). He cycled through custody, bail, and own-recognizance release at different times in different cases. Eventually, he entered a global plea resolving all cases, and the trial court imposed a six-year lead term with concurrent terms on the others at one hearing.

The trial court calculated credits case-by-case, awarding actual and conduct credits that corresponded to the time he was in custody in each specific matter. Cofer sought additional credits—effectively asking that time spent in custody on any one case be credited to each of the other cases (subject to an “after arrest in that case” limitation). The trial court denied that broad request, relying on People v. Jacobs (2013) 220 Cal.App.4th 67.

A divided Court of Appeal in People v. Cofer (2024) 103 Cal.App.5th 333 disagreed and concluded that sentencing all cases in one hearing meant they were the same “proceedings” for § 2900.5(b), entitling Cofer to substantial additional credit. The Supreme Court granted review to resolve the conflict between Jacobs and Cofer.

4. Analysis

4.1. Precedents Cited (and How They Shaped the Decision)

A. Core § 2900.5 “strict causation” line (but addressed a different posture)

• In re Rojas (1979) 23 Cal.3d 152 — Established that § 2900.5 does not authorize credit when the pending proceeding had “no effect whatever” on the defendant’s liberty; credits require attribution to the proceeding at issue.
  Influence here: The Court uses Rojas as part of the broader framework that custody credits are not free-floating; they are tethered to the proceeding/case that caused the custody.
• In re Joyner (1989) 48 Cal.3d 487 — Articulated the “strict causation” principle to avoid duplicative credit windfalls, emphasizing that custody already credited to an unrelated sentence is not “attributable” to a later case unless the defendant would have been free “but for” the later restraint.
  Influence here: Joyner supplies the language of “strict causation,” but the Court explains Joyner did not decide how “proceedings” works when multiple cases are sentenced together.
• People v. Bruner (1995) 9 Cal.4th 1178 — Reaffirmed strict “but for” causation where custody is attributable to multiple, unrelated grounds (e.g., parole violation plus new offense), limiting duplicative credits absent a showing that the new case was the but-for cause of custody.
  Influence here: Bruner is used to clarify that the strict-causation doctrine polices duplicative-credit windfalls across separately imposed sentences; it does not convert a single sentencing hearing into one “proceeding.”
• In re Marquez (2003) 30 Cal.4th 14 — Clarified strict causation applies where there is risk of duplicative credits creating a windfall; allowed credit where an earlier basis for custody later disappeared (reversal/dismissal), leaving custody attributable to the remaining case.
  Influence here: Marquez shows “attributable to proceedings” is an attribution inquiry tied to the underlying case(s), not a mechanical “maximize credits” rule.
• In re Atiles (1983) 33 Cal.3d 805 — Discussed because Joyner criticized it and Bruner overruled it to the extent inconsistent.
  Influence here: The Court underscores that any suggestion of mandatory “maximization” of credits is not controlling.

B. Multiple cases resolved together: “one bargain but multiple cases”

• People v. Soria (2010) 48 Cal.4th 58 — Held that when multiple separately filed cases are resolved by a single plea bargain with separate pleas, they remain separate “cases” for restitution fine purposes: “one bargain but multiple cases.”
  Influence here: Soria provides close analogical reasoning: joint plea/sentencing is an administrative convenience that does not merge separate actions into one proceeding.

C. Court of Appeal authorities in tension

• People v. Jacobs (2013) 220 Cal.App.4th 67 — Held that even if two cases are sentenced at the same hearing, presentence credits are awarded only for custody related to the specific case.
  Influence here: The Supreme Court’s interpretation aligns with Jacobs and effectively validates its approach.
• People v. Cofer (2024) 103 Cal.App.5th 333 — The Court of Appeal majority treated the single sentencing hearing as the relevant “proceedings,” awarding broad cross-case credits (except time preceding arrest in a particular case).
  Influence here: The Supreme Court rejects this construction as inconsistent with statutory text and ordinary meaning.
• People v. Kunath (2012) 203 Cal.App.4th 906 — Read by the Supreme Court as potentially allowing credit in a case to which custody was not attributable; the Court disapproves it to that extent.
  Influence here: This is the opinion’s principal “cleanup” move in the Court of Appeal landscape.

D. Other cited interpretive and ancillary authorities

• City of San Jose v. Superior Court (2017) 2 Cal.5th 608 — Standard statutory-interpretation framework (plain meaning, context, avoid absurdity, consult history if ambiguous).
• People v. Walker (2024) 16 Cal.5th 1024 — Plain meaning as understood by ordinary person.
• Smith v. Superior Court (2006) 39 Cal.4th 77 — Give significance to every word/phrase; read in context.
• Burns v. Superior Court (1903) 140 Cal. 1 and Gipe v. Superior Court (1981) 124 Cal.App.3d 617 — “Proceeding” broader than a “hearing.”
• Vasquez v. State of California (2008) 45 Cal.4th 243 — Courts constrained by statutory text.
• In re Sosa (1980) 102 Cal.App.3d 1002 and People v. Gonzalez (2006) 138 Cal.App.4th 246 — Raised by defendant for “dead time” arguments; distinguished as not supporting transferring credits to an unrelated case where custody is not attributable.
• Skidgel v. California Unemployment Ins. Appeals Bd. (2021) 12 Cal.5th 1 and Torres v. Automobile Club of So. California (1997) 15 Cal.4th 771 — Policy balancing cannot override clear statutory meaning.
• People v. Harvey (1979) 25 Cal.3d 754 — Mentioned because dismissed charges were subject to Harvey waivers; not central to the credit rule.
• People v. Lopez (2012) 55 Cal.4th 569 and People v. Panighetti (2023) 95 Cal.App.5th 978 — Dissenting opinions are not precedent, relevant to defendant’s reliance on a Joyner dissent.

4.2. Legal Reasoning (How the Court Got There)

A. The statutory text controls: “proceedings” means a legal action/case

Section 2900.5(a) broadly awards credit for days spent in custody; section 2900.5(b) limits those credits to custody “attributable to proceedings related to the same conduct for which the defendant has been convicted.” The Court’s interpretive fulcrum is the word “proceedings”.

Using ordinary meaning (including dictionary/legal definitions), the Court reads “proceedings” as the “regular and orderly progression of a lawsuit” — i.e., an individual filed action. In the criminal context, that is a criminal case (a separate prosecution with its own case number).

B. Contextual coherence: custody is attributable to the unfolding case, not to a later joint hearing

The Court rejects the Court of Appeal’s notion that a later single sentencing hearing can retroactively become the “proceedings” to which earlier custody was “attributable.” Custody decisions (bail, remand, holds) occurred as each case “independently unfolded”; attributing those custody days to a later joint hearing misreads causation and statutory structure.

C. “Proceedings” is broader than “hearings”

Relying on authorities such as Burns v. Superior Court (1903) 140 Cal. 1 and Gipe v. Superior Court (1981) 124 Cal.App.3d 617, the Court emphasizes a proceeding can have many stages; a sentencing hearing is only one stage. Therefore equating “proceedings” with “hearing” is linguistically and legally unsound.

D. Harmonizing with how California treats multiple cases resolved together

The Court’s reasoning is reinforced by People v. Soria (2010) 48 Cal.4th 58: even when multiple cases are jointly resolved at plea and sentencing, they remain distinct cases unless formally consolidated. The Court applies the same logic to custody credits under § 2900.5(b).

E. Legislative history supports, or at least does not undermine, the case-based meaning

The Court briefly reviews the statute’s evolution:

• 1971: credits limited to custody attributable to “charges arising from the same criminal act or acts.”
• 1976 amendment: changed “charges arising from” to “proceedings related to,” aimed at ensuring credit for time spent in the California Rehabilitation Center and clarifying creditable custody settings—without indicating any intent to redefine “proceedings” as “sentencing hearings.”
• 1978 amendment: added the second sentence of § 2900.5(b) (credit once for a single period of custody when consecutive sentences imposed), which the Court notes is not the scenario presented.

F. The Court’s limiting clarification: concurrent sentences can each get credit only if custody is attributable to each case

The Court adopts (and quotes) the dissenting view below: credit for the same custody period may be reflected against multiple concurrent sentences in multiple cases so long as the custody is attributable to each of those cases. Thus, the decision does not forbid “overlapping” credits where a defendant is simultaneously held on multiple cases; it forbids cross-case credits untethered from custody attribution.

4.3. Impact (Why This Matters Going Forward)

• Clarified statewide rule: Trial courts must calculate § 2900.5 credits by asking whether the custody time was attributable to the particular case—not by pooling credits across multiple cases because sentencing was coordinated.
• Resolves appellate conflict: The Supreme Court rejects the Court of Appeal’s approach in People v. Cofer (2024) 103 Cal.App.5th 333 and aligns with People v. Jacobs (2013) 220 Cal.App.4th 67.
• Disapproval of outlier authority: People v. Kunath (2012) 203 Cal.App.4th 906 is disapproved to the extent it permits credits in a case to which custody is not attributable, narrowing arguments for global pooling in future litigation.
• Plea bargaining and defense practice: The Court explicitly notes practical mechanisms that may be pursued in negotiations or litigation (e.g., bargaining for pooled/duplicative credits, requesting revocation of release in one case upon custody in another, or raising ineffective assistance via habeas if counsel failed to attempt to optimize credits).
• Equity arguments constrained: The Court signals that policy concerns (including “equal treatment” between defendants who can afford bail and those who cannot) cannot override unambiguous statutory text.

5. Complex Concepts Simplified

• Presentence custody credits (§ 2900.5(a)): Days you spent in custody before sentencing generally reduce the custodial time you must serve after sentencing.
• Conduct credit (often § 4019): Additional credit for complying with rules/participation while in local custody; typically added to “actual” days.
• “Attributable to proceedings” (§ 2900.5(b)): A causal/tethering requirement: the custody day must be because of the case you want the credit applied to. In Cofer, “proceedings” means the individual criminal case.
• Concurrent vs. consecutive sentences: Concurrent terms run at the same time; consecutive terms stack. The second sentence of § 2900.5(b) limits double-counting for a single custody period when consecutive sentences are imposed; Cofer’s main issue involved concurrent terms and the first sentence of § 2900.5(b).
• “Strict causation” / “but for” causation: In credit disputes, courts may require proof you would have been free during that period “but for” the case for which you seek credit—especially to prevent duplicative credits that create a windfall.
• “One bargain but multiple cases” (from People v. Soria (2010) 48 Cal.4th 58): A global plea deal can resolve multiple case numbers at once, but it does not automatically merge them into one action for statutory consequences.
• Harvey waiver (People v. Harvey (1979) 25 Cal.3d 754): Allows sentencing courts to consider facts underlying dismissed counts for sentencing purposes; unrelated to whether custody credits can be pooled.

6. Conclusion

People v. Cofer establishes a clear statewide rule: under Penal Code § 2900.5(b), the word “proceedings” means an individual criminal case, so presentence custody credits may be applied to a sentence only when the custody time is attributable to that case. A single coordinated sentencing hearing does not convert multiple separately filed prosecutions into one “proceeding,” and it does not authorize automatic cross-case pooling of credits. The decision strengthens administrable, text-based credit calculations, resolves a Court of Appeal split, and narrows reliance on People v. Kunath (2012) 203 Cal.App.4th 906.
