This article reviews some of the more important jurisdictional decisions of the U.S. Supreme Court during the court's 2006-07 term, the first full term that included both of the court's newest justices--Chief Justice John G. Roberts Jr. and Associate Samuel A. Alito Jr. The term begins an era that will likely become known as the Roberts Court, but this term surely belonged to Associate Justice Anthony M. Kennedy, who cast the deciding vote in all 24 of the court's 5-4 decisions.
