A South Dakota man accusing the nation's largest meat packers of knowingly underpaying cattle producers says he isn't done fighting.

Herman Schumacher of Herreid and two other men sued the meat packers and initially won. But an appeals court overturned the ruling last year.

Now Schumacher has a lien on his house until he pays Tyson Fresh Foods thousands of dollars in court costs.

Eight years ago, the U.S. Department of Agriculture reported some beef prices incorrectly. Schumacher and the other plaintiffs accused the meatpackers of knowing about the mistake and taking advantage of cattle producers by paying less.

Tyson says it didn't know until the agriculture department announced the mistake so it did nothing wrong.

People stood in the front lawn of Schumacher’s Herried home Friday, many of them showing support. All the while, stickers hung on Herman Schumacher's door, warning he has an overdue bill of almost $16,000.

"It certainly wasn't easy to take," Schumacher said. "Coming from a small community like this, it's an embarrassment no doubt."

The court ruled Tyson was entitled to reimbursement of certain court costs. Tyson said it sent a reminder letter to Schumacher's attorney in January asking for payment within ten days. It's been more than five months since then.

Schumacher says he didn't know.

"I was not given a heads up on this. It was delivered by two U.S. Marshals," Schumacher said.

Schumacher says Tyson is telling the world that it's in charge and the sign on his door is on the door of ever cattle producer that fights back.

Tyson says it's just trying to collect what's owed and is having to go through additional legal steps to do it.

Schumacher isn't sure if he'll have to pay court costs for the other meatpackers he sued. Still, Schumacher says he's not going anywhere.

"Yes there's pending legal action and yes they're not going to shut me up," Schumacher said.

Tyson says it values and depends on independent cattle producers. Schumacher disagrees and says he's seen unfair treatment from packers forcing producers out of business.
