Massachusetts Cahill and Second Section 24D FAQs
G.L. c. 90, § 24D permits one additional disposition in a narrow category of alcohol OUI cases involving a single qualifying prior from 10 years or more before the current alleged offense. Eligibility is limited, the disposition is available only once during a person’s lifetime, and the court retains a statutory role in deciding whether to use it.
In Commonwealth v. Cahill, the Supreme Judicial Court decided the license period that follows a valid additional Section 24D disposition. The complete current eligibility, court, license, hardship, refusal, and ignition-interlock rules appear in the firm’s Massachusetts second Section 24D guide.
Eligibility and the Cahill Decision
The additional disposition is available once during a person’s lifetime. It applies only to a current alcohol OUI when the person has exactly one like-offense conviction or qualifying court-ordered program assignment from any jurisdiction 10 years or more earlier. It is unavailable if the incident caused serious personal injury or death. After conviction at trial, an eligible defendant is presumed an appropriate candidate for Section 24D’s driver alcohol education and court-ordered alcohol or controlled-substance abuse treatment or rehabilitation programs. A judge who deems the defendant unsuitable must make written findings. The defendant receives no presumption of RMV hardship-license eligibility.
Compare the date of the earlier conviction or qualifying court program assignment with the date the current alleged offense was committed. The dates may be exactly 10 years apart; Section 24D does not require a longer interval. The current arrest, arraignment, plea, or sentencing date does not control. Certified records should be used because an informal description of the earlier case may not identify the controlling date or disposition.
In Commonwealth v. Cahill, 442 Mass. 127 (2004), the Supreme Judicial Court decided the license consequence after a valid additional Section 24D disposition. A person who was at least 21 when the current offense was committed receives the 45-to-90-day Section 24D suspension, not the ordinary two-year second-offense revocation. The Supreme Judicial Court did not make the disposition automatic and did not decide the separate refusal suspension, the ignition-interlock requirement, or how the original prior and the additional Section 24D disposition affect a later OUI prosecution.
Court and License Consequences
For an ordinary second offense under G.L. c. 90, § 24, the court must impose a $600-to-$10,000 fine and a committed sentence of 60 days to two and one-half years, with at least 30 days served. Under a separate statutory alternative, the court may impose exactly two years of probation, at least 14 days in residential treatment, and outpatient counseling if the defendant consents and the court makes the required treatment, benefit, and public-safety findings. Neither sentence is mandatory under Section 24D. It permits probation for no more than two years and requires the applicable Section 24D program.
The Section 24D suspension is 210 days if the person was under 21 at the offense. Section 24D states that a person “aged 17 to 21, inclusive,” whose blood alcohol percentage was at least .20 is assigned to the 14-day second-offender in-home program. A separate Section 24P suspension may follow a .02-or-greater alcohol percentage or chemical-test refusal. Its length and program-based waiver or reduction depend on age, history, and entry into a program authorized by Section 24P or required by Section 24D. After Section 24D program entry, the Registry may immediately consider hardship relief during that same-incident Section 24P suspension.
After entering the required Section 24D program, a participant may immediately apply to the Registry of Motor Vehicles for consideration of a limited license. Issuance is discretionary. If granted, the license is valid for the same 12-hour period each day, seven days a week. The Registry may consider the application during a refusal or Section 24P suspension from the same incident. Section 24D does not shorten those suspensions, make consecutive periods concurrent, cover another incident, or guarantee approval. Supporting-document requirements appear in the Section 24D hardship-license guide.
A qualifying prior alone does not trigger the repeat-offender interlock statute. After the current Section 24D suspension and program assignment, a person with that prior must comply with G.L. c. 90, § 24½ before issuance or restoration. The device must be installed in every vehicle the person owns, leases, or operates. For a multiple offender, the Registry requires the device throughout the hardship period and for two years after full reinstatement. Section 24D also permits the Registry to require an ignition interlock device as a hardship-license condition when the current blood alcohol percentage was at least .15.
Refusal, CWOFs, and Later OUI Cases
The Registry imposes a three-year refusal suspension when the person has one ordinary qualifying prior. The Registry imposes that period consecutively to an additional same-incident suspension and any other refusal suspension. The person must request the Registry hearing within 15 days. After Section 24D program entry, the Registry may consider hardship relief during the same-incident refusal. A refusal is ordinarily inadmissible at trial, but a judge may admit it after a misleading cooperation claim. If the person consents but supplies an inadequate sample, counsel may challenge the breath-test foundation. Other refusal periods and procedures appear in the OUI license-suspension guide.
No. Section 24D may be used after an admission to sufficient facts and a continuance without a finding (CWOF), a guilty plea, or a conviction after trial. If the court uses the statutory CWOF procedure, G.L. c. 90, § 24E requires a review 60 to 90 days later and permits dismissal upon satisfactory compliance; dismissal is not automatic. The admission and court-ordered program assignment can remain legally significant, and related court, probation, and Registry records may remain after dismissal. Whether the disposition or assignment counts depends on the governing law.
No. The additional disposition is available once during a person’s lifetime. If that person is later convicted of another alcohol OUI, all qualifying prior convictions and program assignments must be counted under Section 24D. With both earlier events properly alleged and proved, the later prosecution ordinarily is a third offense, not another second offense. Both the earlier prior and the additional disposition remain part of the statutory history.
It can. A conviction or court-ordered program assignment from another jurisdiction counts if it arose from a like offense under a law comparable to the Massachusetts provision. A purely administrative refusal or alcohol-related suspension is not itself a conviction or court assignment. Counsel should compare the certified disposition and foreign statute with Massachusetts law rather than relying on the foreign jurisdiction’s label.
