The Supremes ruled 5-3 against the Bush Administration. There’s discussion here (Andrew McCarthy’s "pre-mortem"), here, and here (another pre-analysis).
After I’ve had a chance to read the opinions, I might have something more to say.
Update: You can read the syllabus, with a little commentary, here and this WaPo article (which, it strikes me, doesn’t say everything that needs to be said). The opinion (all 185 pages) is here.
