Gay marriage foes are livid at now-retired federal judge Vaughn Walker's use of a clip from last year's trial that led to his ruling against Proposition 8, California's gay marriage ban.

Walker declared the 2008 voter-approved constitutional amendment unconstitutional. His ruling, however, has been appealed by the law's sponsors.

Lawyers on Wednesday asked the 9th U.S. Circuit Court of Appeals to forbid Walker from playing recordings of the trial.

Sponsors filed their motion after Walker gave on February 18 a presentation at the University of Arizona which included a clip from the trial, the AP reported. The presentation was also broadcast on C-Span.

In the clip, Ted Olson, a lawyer for the plaintiffs, is seen rebutting lawyer Charles Cooper's arguments that banning gay marriage serves society.

“That is nonsense that you can enact a proposition that walls off the citizens of this state from a fundamental right because you're worried that otherwise children might be prematurely preoccupied with issues of sexuality. If that was a justification, it would equally warrant banning comic books, television, video games, and conversations with other children,” Olson says.

“By releasing the videotape on the eve of leaving the judicial bench, Judge Walker violated a judicial ethic, a clear promise he made to the witnesses, and defied the Supreme Court itself. What more evidence do we need that we have on our hands a rogue judge with little regard for ordinary judicial process and fair play?” Brian Brown, president of the National Organization for Marriage (NOM), the nation's most vociferous opponent of gay marriage, said in a statement.

“Allegations of prejudice and the appearance of bias on the part of Judge Walker are becoming increasingly hard to ignore, given this reckless disregard of normal judicial rules of behavior,” he added.
