A bankruptcy judge has blocked the sale of a factory in Park Hills to a German company. The judge says he won’t approve the deal because the German company wanting to buy parts of the Glass Group will not accept clauses in union contracts that say the contracts stay in effect under new ownership. The judge says he will not void those provisions of the contract. The German company is the only bidder for the Flat River Glass Factory in Park Hills and two other units Glass Group wants to dump.
