The California Supreme Court will hear oral argument in Patterson v Padilla on November 6, at 9 a.m., in Sacramento. This is the case on whether the California Constitution prevents the state from requiring presidential candidates to reveal their tax returns, if they want to be on a presidential primary ballot.
Although a U.S. District Court already enjoined the law on federal constitutional grounds, the state is appealing the federal case. The State Supreme Court case is based on the state constitution.
