Nixon Peabody faces an $8.8 million malpractice lawsuit alleging it bungled a long-running eminent domain dispute while representing the sewer district of New York’s Rockland County against property owners who had hoped to sell a parcel of land to developers.

The suit, first reported by the Rockland County Times, arises out of an underlying case that traces its roots back to 2004. In that dispute, Nixon Peabody represented the Rockland County Sewer District against a group known as the Split Rock Partnership that once owned property near the village of Hillburn, New York.
