SAN FRANCISCO — With witnesses done in the federal trial over Proposition 8, Chief Judge Vaughn Walker will now retire to his chambers and sort through the evidence — aided by a complete video recording of the proceedings. Might those tapes get a public airing?

Cameras emerged as a volatile issue at the beginning of the trial, until the U.S. Supreme Court voted 5-4 to bar broadcast because the Northern District of California bungled a change in its rules. But if the district court properly amends its guidelines to allow for the release of previously recorded videos, David Boies of Boies, Schiller & Flexner said the plaintiff same-sex couples would “absolutely” make a motion to release the Prop 8 tapes.
