152 N.E.3d 725
Mass.2020Background
- Two plainclothes Boston police officers in an unmarked vehicle queried a maroon Mercedes' plate, learned the vehicle lacked an inspection sticker, and stopped it; the driver (defendant), a young Black man, was found to have a suspended license and outstanding warrants; a subsequent search of the towed vehicle uncovered a firearm.
- Defendant moved to suppress, claiming the stop was the product of race-based selective enforcement and that the impound/inventory-search was improper; he produced a statistical expert who analyzed officers' field-interrogation/observation (FIO) reports and citation data against census-based benchmark populations.
- The Superior Court judge denied suppression, finding the statistical and FIO data insufficient under Commonwealth v. Lora to raise a reasonable inference of racial motivation; the defendant obtained leave to pursue an interlocutory appeal to the SJC.
- The SJC majority held the judge abused his discretion: the defendant had produced sufficient evidence to raise a reasonable inference of race-based motivation and thus was entitled to suppression unless the Commonwealth rebutted the inference at a hearing. The court revised Lora’s test to allow nonstatistical totality-of-the-circumstances showings.
- The court adopted an equal-protection framework (Mass. Decl. of Rights arts. 1 and 10) as the appropriate constitutional vehicle; concurring opinions urged broader remedies, including treating pretextual stops as unreasonable under art. 14 and improving officer-specific data collection.
Issues
| Issue | Plaintiff's Argument (Long) | Defendant's/Respondent's Argument (Commonwealth) | Held |
|---|---|---|---|
| Whether defendant raised a reasonable inference that the stop was racially motivated | The FIOs and citation data, analyzed against census benchmarks, show a statistically significant pattern supporting an inference of race-based stops | Data on FIOs/citations and census benchmarks are incomplete/unreliable; Lora requires stronger statistics | SJC: defendant produced sufficient evidence to raise a reasonable inference; judge abused discretion in denying suppression |
| Proper evidentiary standard to raise an initial inference of discriminatory traffic stops | A defendant may rely on totality of circumstances and nonstatistical evidence (including officer conduct, sequence of events, department practices) | Lora requires statistical showing of disparity between stops and benchmark driver population | SJC: revise Lora—defendant may raise inference by specific facts from totality; statistics are permissible but not required |
| Allocation of burdens once inference is raised | If defendant raises reasonable inference, Commonwealth must rebut at a hearing or evidence from the stop is suppressed | Commonwealth argued its showing of a valid traffic justification suffices to rebut | Held: burden shifts to Commonwealth to rebut all reasonable inferences; mere denial or citation of the traffic reason is insufficient |
| Proper constitutional framework: equal protection (arts.1 & 10) vs. art.14 (search & seizure)/authorization test | Long argued under equal protection; majority favors equal protection but lowers its evidentiary burden | Commonwealth/majority: equal protection is the right vehicle; some concurrences argued art.14 should prohibit pretextual stops outright | Court: equal protection remains primary for race-based selective enforcement claims; rejected overruling authorization test but clarified remedies and lowered burdens; concurrences urged art.14 approach for broader remedy |
