A U.S. judge in Newark on Wednesday allowed an arbitration to proceed between two Illinois firms over a portion of $5.775 million in legal fees approved as part of a class action settlement.

Lakin Chapman of Wood River, Ill., claims it has a right to one-third of the fees, or $1.925 million, as damages for breach of contract by the Chicago firm of Freed & Weiss, class counsel in Larson v. Sprint Nextel Corp., 07-cv-5325.
