The decision was announced today; slip opinion available on the Supreme Court’s website.
Contrary to some of the headlines this is not a decision about the quality of Coca-Cola’s beverages, but a ruling that one player in a market (in this case, POM Wonderful) may bring a Lanham Act claim against another (e.g., Coca-Cola, one of POM’s competitors in the fruit juice market) because such claims are not preempted by federal law (i.e., a regulation of the FDCA).
