It was Thursday afternoon and the press was sweating: For three days no one new had decided to go after Hewlett-Packard’s board of directors for their recent descent into public ignominy.

Not to fear, though: At about 4 p.m., plaintiffs lawyer William Lerach joined Congress, the California attorney general, the San Francisco U.S. Attorney, and federal regulators. Representing an HP shareholder, Lerach filed a suit accusing board members and executives of breaching their fiduciary duty for a litany of reasons, including their ongoing use of top Silicon Valley lawyer Larry Sonsini.
