State v. Diano: Inclusion of Misdemeanor Incarceration in Habitual-Offender Cleansing Period

Introduction

In State of Louisiana v. Christopher Raymond Diano (No. 2024-KK-00888), the Louisiana Supreme Court addressed the construction of Louisiana’s Habitual Offender Law, La. R.S. 15:529.1(C)(1). Following a conviction for inciting a felony on January 24, 2021, the State sought to enhance Mr. Diano’s sentence as a fourth-felony offender based on three prior drug convictions (2009, 2010, 2013). Mr. Diano moved to quash, arguing that more than five years had elapsed—i.e., the statutory “cleansing period”—and that the 180 days he served in 2018–2019 on a misdemeanor sentence should not interrupt that period. The district court granted the motion, the First Circuit denied the State’s writ, and the Supreme Court granted certiorari to resolve the disagreement over the statute’s scope.

Summary of the Judgment

Chief Justice Weimer, writing for the majority, affirmed the district court. The Court held that when computing the five-year “cleansing period” in La. R.S. 15:529.1(C)(1), only periods of supervision or incarceration linked to the felony predicates are excluded. Time spent incarcerated on unrelated misdemeanor charges is included in the computation. The Court therefore concluded that Mr. Diano’s three prior felonies were cleansed before January 24, 2021, and quashed the habitual-offender bill. The State’s alternative argument—relying on an asserted split-sentence probation ending April 8, 2016—was rejected for lack of record proof.

Legal Reasoning

The Court began with the plain text of La. R.S. 15:529.1(C)(1). Subsection (C)(1) describes how to compute the five-year intervals “linked solely” to prior felony convictions alleged in the habitual-offender bill. Only “in computing the intervals of time as provided in this Paragraph” are periods of felony-related parole, probation, or incarceration excluded. Reading “this Paragraph” in context confines the exclusion to supervision or imprisonment arising from those very felonies. The State’s approach—excluding every day of incarceration regardless of its relation to the predicates—would sever the text from its context, undermine the statute’s rehabilitative purpose, and yield absurd results (e.g., tolling the cleansing period for jail time on traffic or child-support contempt).

Applying the rule of lenity, the Court resolved any remaining ambiguity in Mr. Diano’s favor. And because the State failed to prove on the existing record that Mr. Diano’s split-sentence probation extended beyond December 25, 2015, the only relevant interruption was the 180-day misdemeanor incarceration—counted in full. Hence, more than five years had elapsed before the January 2021 offense, and enhancement as a fourth offender was improper.

Impact

Clarifies that only felony-related supervision or imprisonment suspends the five-year cleansing clock.
Prevents collateral misdemeanor incarcerations—from traffic, support, or acquitted arrests—from perpetually tolling the statute.
Reinforces strict construction of enhanced-penalty statutes and the rule of lenity.
Signals to trial courts and practitioners to verify and document exact supervision periods for each felony predicate.

Complex Concepts Simplified

Cleansing Period: A five-year span after a felony conviction or end of supervision, during which no new felonies must occur for prior records to “cleanse.”
Habitual Offender Law: An enhancement scheme (La. R.S. 15:529.1) that increases punishments for persons who commit felonies after earlier felony convictions.
Split Sentence: A sentence combining imprisonment and probation—in this case, serving one year in prison followed by three years of probation.
Supervisory Writ: A special application asking an appellate court to review a lower court’s interlocutory ruling (here, the motion to quash the habitual-offender bill).
Rule of Lenity: Ambiguous criminal statutes must be interpreted in the defendant’s favor.
Statutory Interpretation: Courts read statutory language in context, consistent with the law’s object and avoid readings that lead to absurdity.

Conclusion

State v. Diano establishes that, under La. R.S. 15:529.1(C)(1), only felony-related periods of parole, probation, or incarceration interrupt the five-year habitual-offender cleansing period. Misdemeanor jail time—absent a direct link to the felony predicates—must be counted in full. By anchoring the tolling provision to the predicate felonies, the Court preserves the legislature’s goal of focusing enhancements on repeated felonious conduct, avoids absurd tolling for collateral incarcerations, and upholds the strict-construction and lenity principles in criminal law.
