(June 4, 2004) - (Shelbyville, Tennessee-AP) -- A federal appeals court has given the go-ahead for a lawsuit that claims Tyson Foods hired illegal immigrant workers to depress wages at a poultry plant in Tennessee. The 6th U.S. Circuit Court of Appeals says the trial court misapplied federal law and wrongly dismissed the case. But the appellate court said the case could be dismissed on other grounds in the future. In a separate matter, a federal jury in Chattanooga last year acquitted the company and three former managers of conspiring to hire illegal immigrants from Mexico and Central America to fill seven-dollar-an-hour jobs at the company's poultry plants. Two former managers who made plea deals were sentenced to one year of probation.
