A federal appeals court has refused to reopen a lawsuit filed by a retirement system for Hawaii’s public-sector workers that claimed it was defrauded by Whole Foods Market when the upscale grocery chain became ensnared in an overpricing scandal.

The U.S. Court of Appeals for the Fifth Circuit, sitting in New Orleans, said on Oct. 3 that the retirement fund, the Employees’ Retirement System of the State of Hawaii, could not demonstrate that it suffered financial harm when it invested in Whole Foods.
