Lawyers for a Massachusetts woman convicted of involuntary manslaughter last year for pressuring her teenage boyfriend into killing himself are petitioning the Supreme Court to review the case, a report said.

The attorneys for 22-year-old Michelle Carter filed the motion with the Supreme Court on Monday, seeking a review of the conviction on First and Fifth Amendment grounds, according to The Boston Globe.

They argue that Carter’s texts with Conrad Roy III, the teenager who took his own life, “did not constitute speech that was ‘an integral part of conduct in violation of a valid criminal statute,’ ” the paper said.

The motion also questioned whether the conviction violated the due process clause of the Fifth Amendment “because in assisted or encouraged suicide cases, the common law of involuntary manslaughter fails to provide reasonably clear guidelines to prevent ‘arbitrary and discriminatory enforcement.’ ”

Carter was 17 when she urged Roy, 18, to kill himself in a series of text messages and phone calls.

Roy died from carbon monoxide poisoning inside his pickup truck in July 2014.

Juvenile court Judge Lawrence Moniz said Carter was “mindful” of the toxic environment building in Roy’s pickup — yet encouraged the troubled teen to get back in the vehicle.

She was sentenced to serve 15 months in prison.
