The former general counsel of Broadcom Corp., David Dull, has avoided criminal charges in a stock-options backdating case following claims of prosecutorial misconduct.

Dull is expected to reach a nonprosecution agreement with the government, according to court documents. He has not been criminally charged. The indictment leveled securities fraud charges against Henry Nicholas, the former chief executive officer, and William Ruehle, the former chief financial officer, of Broadcom. The U.S. Securities and Exchange Commission (SEC) sued Dull in a related civil action in which he has denied any wrongdoing.
