Good morning and welcome to Supreme Court Brief. The justices wrap up the final week of October arguments with the copyright challenge to Andy Warhol’s “Prince” series. Veteran advocates Roman Martinez of Latham & Watkins and Lisa Blatt of Williams & Connolly go toe-to-toe. We check in on an unusual amicus brief supporting neither party to the case. Remember California’s Prop 8 ban on same-sex marriage? The justices denied a petition seeking to keep sealed the video tapes of the historic trial in 2010. We have details. And scroll down to read how a law professor and a former federal judge offer the justices an alternative to the independent state legislature doctrine in the potential election law blockbuster, Moore v. Harper.
