The Enfield State’s Attorney’s Office Monday decided not to pursue domestic violence charges leveled against one of Connecticut’s most prominent land use attorneys, and dismissed its case against Dwight Merriam.

Merriam, a longtime partner at Robinson & Cole, is now on leave from the firm. He was arrested May 1 for alleged domestic violence against his Russian fiancee. Simsbury police charged the 72-year-old Merriam, who is also a member of the Connecticut Law Tribune’s Editorial Board, with third-degree assault and disorderly conduct. Police said Merriam chased his fiancee around the house and assaulted her with a frying pan. The police report also stated that Merriam left a softball-sized red mark with purple overtones on her hip.
