State Rep. John Lawn, who represents part of Newton, pleaded guilty on July 17 to operating under the influence and leaving the scene of the crime with property damage.

Lawn was arrested by Boston Police and State Police at 1:45 a.m. on July 16 near the State House in Boston, after he crashed his SUV into a parked truck and drove away.

“I deeply regret my actions the other night,” he said after exiting the courthouse. “I take full responsibility for them.”

Lawn apologized to his family, friends and constituents, saying he will work to make sure he doesn’t do this again.

Lawn told police that he was a state representative and that he was coming from the State House, although he told reporters on Thursday that he was coming from a private residence. He refused to take a Breathalyzer test, although he admitted to officers he’d had alcohol that evening.

Massachusetts is an implied consent state, which means that if someone is arrested for OUI, they are implied to have consented to a Breathalyzer.

Officers reported Lawn showing signs of intoxication including the smell of alcohol on his breath, bloodshot eyes and an unsteady gait. They also noticed damage to his vehicle.

There were no injuries from the incident.

While a not guilty plea was initially entered on his behalf, which is standard, Lawn came back shortly after and pleaded guilty to the offense and was released on his own recognizance.

Lawn was sentenced to 45 days without a license, one year of probation for the OUI and six months probation for leaving the scene of a crime. If he doesn’t reoffend within a year, the conviction will be removed from his record, as is standard for first-time offenders.

Lawn will also have to pay a $50 victim of drunk driving fund fee, $250 head injury fund fee, and an additional $250 procedural fee.

Assistant District Attorney Amanda Corin wanted a longer license suspension and an alcohol education program. But Judge Paul Tressler said that he will leave a longer suspension up to the determination of the Registry of Motor Vehicles.

Lawn serves as chair of the Committee on Healthcare Financing, which oversees funding for MassHealth as well as other fiscal matters related to healthcare policy.

First elected in 2012, Lawn represents the 10^th Middlesex District, which includes Ward 1 Precincts 1 and 4 in Newton (Nonantum) and parts of Waltham and Watertown.

Mark Steffen of the Massachusetts Republican Party has called for Lawn to resign, saying “[b]y declaring himself a lawmaker at the time of his arrest, it’s clear Rep. Lawn sought to escape the consequences of his actions. He should resign and offer the residents of Watertown the chance to elect a new representative who doesn’t ask officers to look the other way when he allegedly breaks the law.”

House Speaker Ron Mariano (D – 3rd Norfolk) said he was “deeply disappointed,” but the legislature has not yet announced if it will issue any sanctions on Lawn.
