The combined weight of investigations by state prosecutors, federal regulators and the Department of Justice has forced lawyers in Hewlett-Packard’s boardroom mess to get their own attorneys.

Ann Baskins, the HP general counsel, has hired Berkeley, Calif., white-collar specialist Cristina Arguedas. Kevin Hunsaker, the HP senior counsel and ethics director — who the New York Times has reported was in charge of the boardroom leak investigation — has hired San Diego solo Michael Pancer, who also specializes in white-collar criminal cases.
