The decision last week turned down Eileen Battisti's request to reverse the September 2011 sale of her home outside Aliquippa in western Pennsylvania.

"I paid everything, and didn't know about the $6.30," Battisti said. "For the house to be sold just because of $6.30 is crazy."

Battisti, who still lives in the house, said Monday that she plans to appeal to Commonwealth Court. That court earlier ordered an evidentiary hearing, which led to last week's ruling.

Beaver County Common Pleas Judge Gus Kwidis wrote that the county tax claim bureau complied with notification requirements in state law before the auction. She had previously owed other taxes, but at the time of the sale she owed just $235, including other interest and fees.
