Assembly Bill 1950’s statutory amendments retroactively bar the trial court from adjudicating a probation violation after one year
Kuhnel v. Appellate Division of Superior Court of Contra Costa County (Cal. Ct. App., Dec. 17, 2025, No. A163307) 2025 WL 3652126, at *1–2
Summary: Kuhnel seeks a writ of mandate directing the trial court to terminate her probation on the ground she is entitled to the retroactive benefit of a statutory amendment reducing the length of probationary terms. Formerly, the law generally allowed a court to place a defendant convicted of a misdemeanor on probation for up to three years. (Pen. Code, former § 1203a.) Effective January 1, 2021, this default period was reduced to one year. (Pen. Code, § 1203a.) The California Supreme Court held that because Assembly Bill 1950 applies retroactively to cases that are not yet final, it reduces the length of probationary terms imposed before the new law went into effect and authorizes relief from the consequences of a probationer’s acts committed beyond the new maximum period. (People v. Faial (2025) 18 Cal.5th 199, 205, 210–211 (Faial).)
Kuhnel was originally placed on three years’ probation and allegedly violated its terms during the first year of her probation. The court responded by summarily revoking probation, but not until early in the second year. These events all occurred well before Assembly Bill 1950 was enacted or went into effect, and they were appropriate under then-governing law. (See § 1203.3, subd. (a).) The issue is whether the rule of retroactivity prevents the court from adjudicating the violation, alleged to have occurred during the period when probation was unquestionably proper, on the ground that probation was not summarily revoked until after the maximum probationary period allowed under Assembly Bill 1950.
