The family statement described Boies as “a force of nature,” who went up against huge companies on cases involving employment, antitrust, and consumer fraud issues. Boies’s father, firm founder and chairman David Boies, described his daughter as “indefatigable” to The Miami Herald yesterday. He noted that she worked with him on some of his biggest cases, including the Bush v. Gore proceedings to determine the winner of the 2000 presidential election, and the effort to overturn California’s gay marriage ban.

In 2006, Caryl Boies took over a case representing the Archdiocese of Milwaukee Supporting Fund, the lead plaintiff against the Halliburton Company in a securities fraud case. Though class certification for the case was initially denied in district court and in the Fifth Circuit, Boies learned shortly before her death that her cert petition resulted in a recommendation from the solicitor general that the Supreme Court review the appeal, her family said.
