In a landmark ruling on local ordinances designed to banish sex offenders, the Massachusetts Supreme Judicial Court today struck down a sex offender residency ordinance in the city of Lynn.

In 2012, the ACLU of Massachusetts and the Committee for Public Counsel Services sued to challenge the restrictions, in a case now known as Doe v. City of Lynn. The Court found these restrictions unlawful, unsafe and ineffective. Their ruling will have the effect of invalidating about 40 similar ordinances in communities across the state.

"The Supreme Judicial Court has unanimously recognized that local ordinances seeking to banish sex offenders are incompatible with state law and, in all likelihood, make the public less safe," says Jessie Rossman, a staff attorney with the ACLU of Massachusetts. "The Court also wrote that 'the days are long since past'—citing the internment of Americans of Japanese descent and the forced migration of Native Americans—when entire groups of people 'may be lawfully banished from our midst.'"

The Court recognized, too, that when lawmakers created the state sex offender registry, the Legislature chose a path meant to protect the public. Ordinances like Lynn's stand in the way of that intent. "Local residency restrictions undermine the state system by forcing sex offenders into homelessness, which makes them harder to find and destabilizes rehabilitation," Rossman says.

Ordinances like this also fail to create safe communities. “Our image of the sex offender lurking on the edges of our school playground and parks is simply not true,” explains Dr. Laura Guidry, president of the Massachusetts Association for the Treatment of Sexual Abusers. Dr. Guidry cites figures from the Justice Department, which show that 93 percent of children who are sexually abused are harmed by family members, close friends or acquaintances. This means that residence restrictions will do nothing to stop the most common situations in which children are sexually abused. “What does work are restrictions based upon a careful risk assessment that looks at the risks posed by each individual adult or adolescent in question,” Guidry says.

The Massachusetts ruling comes as part of a growing national trend, in which high courts and officials in states such as New York and California have rejected similar restrictions.
