89 N.E.3d 1159
Mass.2018Background
- A clerk-magistrate issued a delinquency complaint (May 25, 2016) charging a 12-year-old juvenile with nighttime breaking and entering (building and vehicle), larceny over $250, and disorderly conduct based on police reports of the juvenile carrying firearms, entering vehicles/buildings, and making violent statements.
- Police found long rifles and later a revolver near an apartment; witnesses reported a boy (approx. 10–12) carrying a long rifle, pulling the trigger, and entering vehicles.
- Officers observed the juvenile acting agitated and making “deranged” statements (e.g., declaring himself “Satan,” threatening violence); his mother reported prior police contact and that he had autism and missed medication.
- The juvenile moved to dismiss prearraignment. Relying on the complaint application (the four corners) and attached exhibit, the Juvenile Court judge dismissed all charges, concluding there was insufficient probable cause as to requisite intent because of mental impairment and the juvenile’s age, and also stated dismissal was in the child’s best interests.
- The Commonwealth appealed; the Supreme Judicial Court vacated the prearraignment dismissal and remanded, addressing (1) the proper scope of a probable cause review and (2) whether a judge may dismiss a complaint supported by probable cause on best‑interest grounds before arraignment.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether a judge may consider criminal responsibility or mental impairment when deciding probable cause from the four corners of the complaint application | Commonwealth: complaint application established probable cause as to acts/intent; judge erred by factoring impairment/irresponsibility into probable cause | Juvenile: judge properly considered mental state and age to conclude lack of requisite intent for probable cause | Court: mental impairment or lack of criminal responsibility is not part of the probable cause calculus based on the complaint four corners; those are trial issues requiring notice and evidence; reversal of dismissal on this ground |
| Whether a juvenile’s age can be treated as mental impairment for probable cause purposes | Commonwealth: age may inform limited inferences but not substitute for mental‑impairment inquiry | Juvenile: age and adolescent brain immaturity are relevant to capacity to form intent | Court: age may inform weight of some inferences (e.g., nervousness) but cannot be treated as a mental‑impairment basis to defeat probable cause; age‑based capacity arguments are not part of probable cause review |
| Whether a Juvenile Court judge may dismiss a complaint supported by probable cause before arraignment because dismissal is in the child’s best interests and the interests of justice | Juvenile: Humberto H. permits prearraignment dismissal in the child’s best interests even where probable cause exists | Commonwealth: prosecutor has exclusive discretion to pursue charges once probable cause exists | Court: Humberto H. does not authorize dismissal before arraignment where complaint is supported by probable cause and prosecutor seeks arraignment; prosecutor’s charging discretion controls |
| Proper role of prosecutor and remedies when juvenile has mental health needs | Juvenile: judge should protect child from collateral harms (CARI) by dismissing early | Commonwealth/State: prosecutors should exercise discretion and diversion alternatives prior to arraignment; judges lack power to override prosecutorial decision | Court: judges cannot dismiss valid complaints over prosecutor’s objection; urges prosecutors to consider diversion and best‑interest alternatives before arraignment |
