The grandmother of a New Jersey infant who was permanently disabled as a result of child abuse, and whose $166 million verdict against the state was reversed, is now suing their former attorney and his firm for legal malpractice.

The lawsuit was filed Nov. 22 in Essex County Superior Court by the child's grandmother, Noemi Escobar, against David Mazie and his firm, Roseland's Mazie Slater Katz & Freeman.

Escobar is now represented by Mazie's former partner, Bruce Nagel. The two lawyers have a history of more than a decade of acrimony, dating back to when Mazie split with Nagel to form his own firm. Mazie Slater was formed in 2006, when Mazie led a defection from Nagel, Rice & Mazie, taking a number of cases with him that led to disputes over counsel fees. Both Mazie's firm and Nagel's—Nagel Rice—share office space in Roseland but the two lawyers do not speak to or acknowledge each other in public.
