Lawyers for Kellogg Brown & Root Services Inc. are fighting back against a petition for a full federal appeals court in Washington to hear a dispute over company documents that a three-judge panel decided are privileged.

Vinson & Elkins partner John Elwood and other KBR lawyers wrote in a court filing submitted on Wednesday that the ruling doesn’t warrant a review by the full U.S. Court of Appeals for the D.C. Circuit. The petition for a rehearing on the matter doesn’t “show even tension (never mind conflict)” with other appellate court decisions, they wrote.
