A New Jersey appeals court has overturned an order compelling arbitration of a malpractice suit brought by a former client against Sills Cummis & Gross in Newark.

A Sills Cummis arbitration agreement violated the Rules of Professional Conduct and is unenforceable because it referenced 33 pages of JAMS arbitration rules, yet the client was never given a copy of those rules, the appeals court said in Delaney v. Dickey on Friday.
