On November 17, the United States government filed this brief in opposition, in Clemons v U.S. Department of Commerce, 10-291. This is the case that says that “one person, one vote” principles require that the size of the U.S. House of Representatives be increased. As things stand, Montana and Wyoming each have one seat, but Montana has twice as many people as Wyoming. Thanks to Michael Warnken for the brief. UPDATE: here is the reply brief, which responds to the government’s arguments.
