The 26 state government plaintiffs have filed their reply brief in Florida v. HHS (No. 11-440). You can access that brief here.
Also, I should note (as most of you probably know already) that the Supreme Court has set up a web page with the documents that have been filed in these cases. You can access that page here. It is unclear whether this page will also house access to the avalanche of amicus curiae briefs that soon awaits us. We should find out soon.
