The Oklahoma Supreme Court on Tuesday tossed a $10 million jury verdict against Tyson Foods Inc., granting the company's request for a new trial based on allegations of juror misconduct and a mistake on interpreting the law.

Springdale, Ark.-based Tyson Foods claimed on appeal that some prospective jurors in the trial in McCurtain County, Okla., didn't answer questions fully or truthfully on juror questionnaires and the trial judge didn't allow oral questions on items covered in the forms filled out by the panelists.

The high court also agreed with Tyson that the growers weren't covered by the Oklahoma Consumer Protection Act. Growers had argued that since Tyson provided them with feed and chicks, that gave them standing as consumers.

Tyson has a large operation in the region, with more than 180 poultry producers in southwest Arkansas and southeast Oklahoma that raise broilers for Tyson's plant in Broken Bow, Okla. That plant and its related operations, including a feed mill, employ more than 1,700 people.

In 2008, 54 growers, with Rusty Armstrong as lead plaintiff, sued Tyson, claiming that farmers who didn't want to modernize their equipment were given inferior feed and chicks. They claimed that Tyson had favored growers who got better feed and livestock.
