The Supreme Court released opinions in four argued cases this morning: American Trucking Assn. v. Los Angeles, Tarrant Regional Water District v. Hermann, United States v. Davila, and Association for Molecular Pathology v. Myriad Genetics. All four were unanimous in the judgment. (Justice Scalia authored opinions concurring-in-part and concurring in the judgment in Davila and AMP v. Myriad.) SCOTUSBlog has details, as always.
