For only the second time in its history, the Supreme Court released same day audio tapes of oral arguments, in this instance, for the Grutter v. Bollinger and Gratz v. Bollinger affirmative action cases. The first time the court released same day hearing tapes to the public they did so on a time delayed basis during the Bush-Gore presidential controversy in December 2000.
