Gibson, Dunn & Crutcher‘s Theodore Olson and Boies, Schiller & Flexner‘s David Boies released a video on the eve of the latest round of oral arguments in their ongoing challenge of California’s controversial same-sex marriage ban, Proposition 8.

Steering clear of the recent controversy surrounding District Judge Vaughn Walker, and Monday’s scheduled hearing before Chief Judge James Ware of San Francisco federal district court to vacate Walker’s decision on account of his sexual orientation, Olson and Boies go back to the basics in the video, emphasizing what they say is the central issue in the case: civil rights.

Boies and Olson draw a clear parallel between their case (now know as Perry v. Brown) and the landmark Supreme Court case Loving v. Virginia, which struck down state laws banning interracial marriages as unconstitutional (the case celebrates its 44th anniversary on June 12).
