One of the most high-profile actions against a general counsel for illegal backdating of share options has failed after US regulators this week dropped charges against ex-McAfee legal head Kent Roberts.

The Securities and Exchange Commission (SEC) dropped its charges against Roberts in a court filing on Thursday (19 March). Roberts, who had been accused of backdating stock options for himself and others at McAfee in 2000, had already beaten criminal charges before a San Francisco federal jury in October.
