When demand for the plant's batteries didn't meet expectations, the company filled orders with cells made at a factory in South Korea, leaving the Michigan plant largely idle, according to the report by the Department of Energy's Inspector General, Gregory Friedman.
The report says Cadbury reprogrammed its accounting system so employees could submit false invoices, purchase orders and other documents that made it seem as if a new plant were operating, even though it couldn't have been doing so legally.
