Wallace W. v. Commonwealth, 128 N.E.3d 581

Background

In 2018 the Legislature amended G. L. c. 119, § 52 to exclude from Juvenile Court jurisdiction "a first offense of a misdemeanor" punishable by a fine or by jail/house of correction up to six months.
A juvenile was charged with unlicensed operation (a six months-or-less misdemeanor) and moved to dismiss under § 52, arguing he had no prior delinquency adjudications.
The Juvenile Court denied dismissal based on prior probable-cause findings in earlier matters; the juvenile sought relief in the county court and the case was reported to the full court.
The central legal question was the meaning of "first offense" in § 52: whether it (1) applies only once (a single first misdemeanor ever) or to each distinct misdemeanor, and (2) whether a prior adjudication is required or a probable-cause finding suffices to deprive a juvenile of the statutory "second chance."
The Supreme Judicial Court held that the exclusion was intended as a one-time "second chance" for an isolated misdemeanor and construed "first offense" in favor of juveniles to mean a prior adjudication of delinquency, but provided a procedure to avoid a practical "Catch-22."

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Scope of the exclusion: does "first offense of a misdemeanor" exclude each separate six-months-or-less misdemeanor or only the juvenile's single first such misdemeanor?	Juvenile: applies to the first time for every distinct six‑months-or‑less misdemeanor (would bar jurisdiction for each individual first commission).	Commonwealth: a one-time exclusion — only the juvenile's first commission of any six‑months‑or‑less misdemeanor is excluded.	Held: exclusion is a one-time "first" — it excuses only a juvenile's single first commission of such a misdemeanor; Juvenile Court has jurisdiction over repeat offenses.
What constitutes a "first offense" — is a prior adjudication required, or is a prior probable‑cause finding sufficient?	Juvenile: "first offense" exists unless there was a prior delinquency adjudication — otherwise dismissal is required.	Commonwealth: a prior probable‑cause finding suffices to show that a "first offense" already occurred.	Held: Ambiguous statute construed under rule of lenity in favor of juvenile — "first offense" means a prior adjudication of delinquency; probable cause alone is insufficient.
How to avoid a practical "Catch‑22" where a first offense is dismissed before any adjudication, preventing proof of a later repeat offense? (procedural remedy)	Juvenile: not directly advocating, but prefers protection from proceeding absent adjudication.	Commonwealth: must be able to prove prior misconduct to proceed on subsequent charges.	Held: Court sets procedure: where no prior adjudication exists but repeat misconduct is alleged (or parallel/open more serious charges exist), the Commonwealth may notify intent to prove multiple offenses and a prearraignment evidentiary hearing is required; Commonwealth must prove prior offense beyond a reasonable doubt before arraignment proceeds.
