a class-action lawsuit was filed against Camacho claiming refunds of approximately $112 million as a result of the earned income tax credit. The complaint was amended in 2006 wherein the class asked for approximately $135 million. The parties settled the case for $90 million. In anticipation of the court's approval of the settlement agreement, the Camacho Administration managed to set aside millions of dollars in order to begin payments according to the terms of the settlement agreement.
