Obama Barred Constitutionally From Accepting Nobel - washingtonpost.com

"The award of the peace prize to a sitting president is not unprecedented. But Theodore Roosevelt and Woodrow Wilson received the honor for their past actions: Roosevelt's efforts to end the Russo-Japanese War, and Wilson's work in establishing the League of Nations. Obama's award is different. It is intended to affect future action. As a member of the Nobel Committee explained, the prize should encourage Obama to meet his goal of nuclear disarmament. It raises important legal questions for the second time in less than 10 months -- questions not discussed, much less adequately addressed anywhere else."
