Federal prosecutors don’t intend to let the late convicted Enron founder Kenneth Lay’s record be wiped clean without a fight.

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.
