In a case that seeks to raise questions about the limits of arbitration clauses in law firm retainer agreements, a New Jersey judge has declined to invalidate such a clause used by Sills Cummis & Gross in a bid to recover upward of $400,000 in allegedly unpaid fees.

Essex County General Equity Judge Walter Koprowski Jr. on Thursday denied an application to stay arbitration proceedings in Delaney v. Dickey, where the plaintiff, a former client of Sills Cummis and other firms, contends that his pursuit of legal malpractice claims against the firm should move the whole dispute to court.
