CLEVELAND, Ohio -- A trucking company in Mobile, Ala., is the latest to sue Browns’ owner Jimmy Haslam's Pilot Flying J.

Wright Transportation Inc. filed a federal complaint Wednesday in the southern district of Alabama. The suit claims fraud in diesel gas rebates and seeks a class action for itself and scores of other trucking companies "shortchanged'' by Pilot Flying J.

The suit, filed by Mobile lawyer Stephen Tunstall, names Pilot Flying J and related companies; Haslam; Mark Hazelwood, the company president; John Freeman, vice president of sales; and Brian Mosher, director of national sales.

Wright Transportation charged that it was “victimized’’ by a scheme to “secretly and unlawfully withhold diesel fuel price rebates and/or discounts.’’

Haslam has said he had no knowledge of any rebate shortages and became aware of them only after the April 15 raid by federal agents on Pilot headquarters in Knoxville, Tenn., and at the homes of several sales managers.

Haslam has said Pilot Flying J will pay trucking companies for any amounts they are owed for fuel rebates, plus interest.

Wright Transportation said it signed a contract in 2005 with a Pilot Flying J sales agent whose home was raided by the FBI. The salesman reported to Freeman, the vice president of sales, the lawsuit said.

The lawsuit cites the FBI affidavit used to search Pilot offices. The document detailed systematic cheating of trucking customers who bought diesel fuel from Pilot fuel stations and travel plazas across the country.

The scheme “was given the blessing of Haslam,’’ the Wright Transportation lawsuit said.
