Walker's order certainly suggests he is willing to take seriously the plaintiffs' argument against Prop. 8 as an improper deprivation of constitutional rights.
As a person who has generated campaign memos, I'm mightily curious about what will come out. I assume the motivation for Prop. 8 was malice against gay equality, but I would not be surprised if plaintiffs have a hard time proving it.
It feels ironic that Judge Walker is the guy who gets to decide these arguments. Like much of the LGBT community, I was horrified by his appointment to the Federal bench in 1987 by Ronald Reagan. For gay people of that era, he was the establishment attorney who had hounded former decathlete Dr. Tom Waddell for having launched the "Gay Olympics," thereby infringing on the U.S. Olympic Committee copyright. We saw the copyright case as transparent bigotry -- they never objected to such usages as the Police Olympics. But when the gays wanted their own sporting fest, somehow that would hurt the USOC's property. Waddell was dying of AIDS when Walker got a lien on his house to cover USOC legal expenses. The Gay Olympics were eventually renamed the Gay Games -- and Waddell died wondering what he'd be able to leave to his daughter. We fought Walker's confirmation for two years.
Nowadays, Walker is known to civil libertarians as the judge who has kept alive some miniscule possibility of discovery of the scale of the Bush administration's grab-bag wire tapping. He has refused both Bush and Obama administration requests for a blanket dismissal. Who knew this white male heterosexual pillar of the establishment would turn out to be a jurist who charted his own interesting course? How very San Francisco of him ...
