___________________ October 7, 1997 ____________________ GSBCA 13741-RATE In the Matter of TRI-STATE MOTOR TRANSIT CO. Robert D. Norcom, Auditor, Tri-State Motor Transit Co., Joplin, MO, appearing for Claimant. Jeffrey J. Thurston, Director, Office of Transportation Audits, General Services Administration, Washington, DC, appearing for General Services Administration. Col. James F. Quinn, Staff Judge Advocate, Headquarters, Military Traffic Management Command, Department of the Army, Falls Church, VA, appearing for Department of Defense. PARKER, Board Judge. Tri-State Motor Transit Co. billed the Navy under its Tender Number 582 for transporting eight rockets, three "booster fin sets," and a logbook. Tender 582 covers "freight-all-kinds." After auditing the transaction, the General Services Administration's Office of Transportation Audits determined that the Government had been overcharged in the amount of $1,353.96 because the shipment should have been billed under Tri-State's Tender Number 611, which covers "missiles or rockets." Tri-State asked the General Accounting Office to review the propriety of GSA's deduction. Tri-State initially argued that Tender Number 611 was not applicable because the booster fin sets were not an integral part of the rockets. Thus, according to Tri-State, only its Tender Number 582, covering freight-all-kinds, was applicable to this mixed shipment. Tri-State does not dispute that Tender Number 611 is applicable to the rockets themselves -- it argues only that the addition of the booster fin sets changed the shipment into a mixed one to which the freight-all-kinds tender applies. In response to Tri-State's argument, the Government explained, through an affidavit from an official of the company that manufactured the rockets, that booster fin sets are considered integral parts of a rocket. The booster fins, which are used for guidance control and stability, are attached to the rocket or missile once it reaches its destination. The logbooks, he explained, are also essential to the operation of the missile and are required to be shipped with it. Tri-State disagrees with this conclusion, arguing that the booster fin sets could not have been integral parts of the rockets shipped because there were only three sets of fins for eight rockets. Discussion The Board's Rule of Procedure 301(b) reflects a fundamental principle applicable to claims against the Government: "The burden is on the claimant to establish . . . the liability of the agency, and the claimant's right to payment." 48 CFR 6103.1(b) (1996). Tri-State has not met that burden here. The Government has established that booster fins are an integral part of a rocket or missile; the booster fins are packed separately only for shipping purposes. We have no idea why the Navy shipped only three sets of booster fins with eight rockets. The fact that it did, however, does not establish that the booster fin sets were not part of three of the shipped rockets. Tri-States' claim thus fails for lack of proof. _______________________ ROBERT W. PARKER Board Judge
