Massachusetts-Specific Considerations
- Massachusetts abolished mandatory minimum sentences for several low-level drug offenses in its 2018 criminal justice reform law, giving mitigation exhibits more weight at sentencing
- Mass. R. Crim. P. 14 requires the prosecution to produce automatic discovery items within roughly 21 days of arraignment, a clock defense counsel should track independently of the pretrial conference schedule
- Breath-test calibration and maintenance logs became a standard defense exhibit after 2017 litigation exposed source-code and reliability issues with the Commonwealth's Alcotest breathalyzer devices
- Felonies generally proceed in Superior Court while most misdemeanors and some felonies go through District Court's concurrent jurisdiction, and exhibit procedures can differ between the two

Frequently Asked Questions
How did Massachusetts change mandatory minimum sentencing, and why does it matter for exhibits?
Massachusetts abolished mandatory minimum sentences for several low-level drug offenses in its 2018 criminal justice reform law, which gives judges more discretion at sentencing and makes mitigation exhibits — treatment history, employment records, letters of support — more likely to actually affect the outcome.
What discovery deadline applies in a Massachusetts criminal case?
Mass. R. Crim. P. 14 requires the prosecution to produce a specific list of automatic discovery items, generally within about 21 days of arraignment, covering police reports, witness statements, and any exculpatory evidence. Defense counsel should track that clock closely, since it runs independently of any later pretrial conference schedule.
How do breathalyzer records come up as exhibits in a Massachusetts OUI case?
Breath-test calibration and maintenance logs became a major discovery issue after 2017 litigation over the Commonwealth's Alcotest breathalyzer revealed source-code and reliability problems in certain machines, so defense counsel routinely request the specific device's calibration history as an exhibit rather than accepting the printed result alone.
Does a Massachusetts case go to Superior Court or District Court, and does it change exhibit practice?
Felonies generally proceed in Superior Court while most misdemeanors and some felonies go through District Court's concurrent jurisdiction, and exhibit procedures can differ between the two — Superior Court cases often involve more formal pretrial conferences. Confirm which court has the case before assuming one set of local rules applies.
What e-filing limits apply to police report and video exhibits in Massachusetts?
Tyler Odyssey handles Massachusetts e-filing with a per-document cap commonly cited around 25 MB (confirm the current limit before filing), usually enough for police reports but tight for body camera stills or lengthy discovery productions. Massachusetts also requires exhibit pages numbered consecutively across the whole set, so plan the numbering before assembling a multi-exhibit discovery binder.
