On October 1, the U.S. Supreme Court denied mandamus in Citizens for Fair Representation v Padilla, 18-123. This is the case in which some California local governments, minor parties, and voters challenge California legislative districts for having such huge populations that, effectively, ordinary people can’t influence their state legislators. The plaintiffs had asked the U.S. Supreme Court to rule that the U.S. District Court should appoint a three-judge court. The U.S. District Court Judge had first said she would appoint a three-judge court, but then she changed her mind, allegedly because the chief judge of the Ninth Circuit told her not to arrange for a 3-judge court. The plaintiffs had then asked the U.S. Supreme Court to intervene, arguing that it isn’t proper for the U.S. District Court to defer to any other court or judge, because the U.S. District Court Judge is the only one who will be familiar with the case. But the U.S. Supreme Court declined to get involved.
The case can proceed without a 3-judge court, of course. California legislative districts have almost 1,000,000 residents for each State Senate district, and 500,000 for each Assembly district.
