The Obama justice department succeeded in convincing the five right-wing Supreme Court justices to dismiss a lawsuit challenging the constitutionality of the 2008 law, the FISA Amendments Act, which vastly expanded the government's authority to eavesdrop on Americans without warrants. In the case of Clapper v. Amnesty International, Justice Samuel Alito wrote the opinion, released today, which adopted the argument of the Obama DOJ, while the Court's four less conservative justices (Ginsberg, Breyer, Sotomayor and Kagan) all dissented. This means that the lawsuit is dismissed without any ruling on whether the US government's new eavesdropping powers violate core constitutional rights. The background of this case is vital to understanding why this is so significant.
