The U.S. Supreme Court did not release any full opinions on April 21, but it probably will on April 22. That might include the Indiana government photo-ID case for voting at the polls. Also, on April 22 the Court hears arguments in Davis v Federal Election Commission, the case over the part of the McCain-Feingold law called the “Millionaires’ Amendment.” UPDATE: RicK Hasen of electionlawblog says that there will be no U.S. Supreme Court opinions on April 22, but there may be some on April 23 (Wednesday). If the Indiana case doesn’t come down on April 23, the next possible date is April 28.
