OUI Defense
An OUI charge runs on two tracks at once — a criminal case in court and a separate license proceeding at the Registry. They move on different clocks, and missing the second one costs people their license even when the criminal case goes well.
What the Commonwealth has to prove
An OUI prosecution requires the Commonwealth to prove, beyond a reasonable doubt, that you operated a motor vehicle, on a public way, while under the influence of alcohol or drugs. Each of those elements is a place where a case can fail, and each of them gets examined.
Most OUI cases are built out of an officer's observations: driving, odor, speech, eyes, balance, and performance on roadside tests. Those observations are opinions recorded in a report. Cross-examination is where they get tested.
Field sobriety tests
Roadside tests — the walk-and-turn, the one-leg stand, horizontal gaze nystagmus — are observational tools an officer uses to articulate impairment in a report. They are not pass/fail in any clean sense, and performance on them is affected by age, weight, injury, footwear, road surface, weather, and nerves.
Whether the tests were properly administered, properly recorded, and properly described is litigable.
The breath test and refusal
Massachusetts has an implied-consent law. Refusing a chemical breath test after a lawful OUI arrest triggers an automatic license suspension by the Registry that is separate from the criminal case. Taking the test and registering above the legal limit triggers a different suspension on a different timeline.
Breath testing equipment has to be calibrated, certified and properly operated. Those records are discoverable, and they are worth getting.
Your license and the Registry
The RMV consequences of an OUI arrest can begin before your first court date and proceed whether or not the criminal case is resolved. Hardship licenses, hearing deadlines and reinstatement requirements each have their own rules.
If driving is how you get to work, say so at our first conversation. It changes the order in which things need to happen.
Prior offenses and why a CWOF still counts
Massachusetts OUI penalties escalate with prior offenses, and there is no lookback period that erases an old one. A continuance without a finding on an OUI counts as a prior offense for this purpose — a disposition that avoided a conviction ten years ago will still make a new charge a second offense.
If you have any prior OUI-related disposition, anywhere, bring it up early.
Common questions
Should I have refused the breath test?
There is no universal right answer, and it depends on your history and the other evidence. What matters now is what the record actually shows and what can be challenged.
Will I lose my license?
Possibly, and the license question moves separately from the criminal case. Deadlines are short, so raise it at the first conversation.
Is a first-offense OUI a big deal?
It carries real consequences and it never goes away for purposes of counting future offenses. It is worth defending carefully.
