YORK COUNTY. SC — Fallout from the failed Carolina Panthers headquarters project has spilled into public battles and courtrooms in recent months. This week, David Tepper’s GT Real Estate Holdings LLC fought off a lawsuit filed by York County against other Tepper entities.

On July 14, GT Real Estate filed adversarial proceedings against York County in the U.S. Bankruptcy Court for the District of Delaware, which is hearing GT Real Estate’s Chapter 11 case. The complaint targets the York County lawsuit claiming that $21 million in county funds used by GT Real Estate must be returned. The county’s lawsuit against Appaloosa Management LP, Tepper Sports Holding Inc. and DT Sports Holding LLC was originally filed in state court last month and sought to have that money reimbursed by the other entities run by Tepper.

Andy Houston, a Charlotte bankruptcy attorney for Moon Wright & Houston, said the new complaint was likely GT Real Estate’s effort to move York County’s lawsuit to bankruptcy court. Although York County is not suing GT Real Estate in this case, GT Real Estate says the county’s arguments “are based on the premise that (GT Real Estate) committed the same alleged wrongdoing as (other Tepper entities sued by York County), acting under their direction.”

GT Real Estate’s complaint filed this week says county funds were provided “without any binding contractual obligations governing its use.” The county says the money was for a road expansion project at the headquarters project site which was not completed.
