Justice Alito wrote the majority opinion for the contraceptive mandate case, ruling in favor of Hobby Lobby. The ruling holds that the government cannot require "closely-held" corporations to provide birth control. The decision was split 5-4.
Justice Kennedy joined Alito and the other conservative justices, but also wrote his own opinion. Three justices (Ginsburg, Breyer, and Kagan) offered dissents. Those are available following the majority opinion in this document.
