HOUSTON (AP) - Federal prosecutors will oppose a request by lawyers for Kenneth Lay to legally clear the name of the late founder of Enron Corp., convicted earlier this year on criminal charges related to the biggest corporate scandal in U.S. history. Lawyers for Lay's estate filed court papers Wednesday formally asking a judge to erase Lay's convictions and dismiss the indictment against him because he died before he had appealed. Lay was convicted of 10 counts of fraud, conspiracy and lying to banks in two separate cases on May 25, and died of heart disease July 5. However, a one-sentence addition to the filing revealed that prosecutors aren't willing to rubber-stamp the request. .
