Looks like Northern District of California Chief Judge Vaughn Walker is going to suffer his first reversal in the federal challenge to Proposition 8.

The 9th U.S. Circuit Court of Appeals continued a stay of Walker’s order forcing the Yes on 8 campaign to turn over internal documents and e-mails to challengers of the measure. In its order, the court said the campaign had made a “strong showing” that it would succeed on the merits of the discovery issue.
