At issue were the accounting practices the team used to argue that the 2010 spill caused the team's revenues to fall. The Bucs had sought $19.5 million in damages.
On Friday, the 5th U.S. Circuit Court of Appeals upheld a district court's decision against the team.
The court found that the Bucs' revenue in May-June 2010 was not significantly lower than its revenue during that same span a year later. In order to qualify for damages, it had needed to show that its revenues rebounded by at least 10% in 2011.
The team’s stadium is about 360 miles (580 kilometers) southeast of the site of the spill.
