A reader over at SL&P notes that the Supreme Court on Jan. 16 asked the Solicitor General to respond to a certiorari petition claiming that 21 U.S.C. § 841 violates multiple constitutional rights. That section specifies punishment for possessing various quantities of drugs, and it equates 5 grams of crack with 500 grams of powder cocaine. The case is Jackson v. United States, No. 06-8391. The Ninth Circuit's unpublished memorandum (by Judges Pregerson, Nelson, and Graber) simply notes that the arguments are foreclosed by circuit precedent.
