The Supreme Court granted certiorari today in two cases to further explore the fallout from United States v. Booker regarding how the "reasonableness" of a sentence fits with Sentencing Guidelines after Booker's demotion of the Guidelines to advisory status. Here are the docket and Eighth Circuit opinion in Claiborne v. United States, No. 06-5618, and the docket and Fourth Circuit opinion in Rita v. United States, No. 06-5754. The Court did not put the briefing on a fast track, so we are probably looking at argument at the very end of February at the earliest. Lyle Denniston has this post at SCOTUSblog, and Doug Berman at SL&P is overjoyed.
