According to Law360, An Oklahoma federal judge found insufficient evidence Thursday to keep alive a cellphone retailer's lawsuit accusing his former tax lawyer of negligently allowing a $2.1 million tax debt to balloon to $9.5 million, tossing the suit because it didn't show the outcome could have been any different.

U.S. District Judge Robin J. Cauthron threw out the lawsuit against Travis W. Watkins and the law firm that bears his name because Cricket Wireless cellular store operator Camron McAllister hadn't shown the necessary “but for,” where he would have gotten a favorable outcome from the Internal Revenue Service if it weren't for Watkins' allegedly shoddy work.
