The Supreme Court has completed its latest term after announcing its most hotly debated and consequential decisions. Those rulings can overshadow broader trends. The nine justices have finished their fourth term together, and their thousands of votes in 280 signed decisions in argued cases in those years show some clear and sometimes surprising patterns.

The justices are one of the lasting legacies of the presidents who appoint them, and you might expect ones appointed by the same president to vote together particularly often. This is certainly true of the four newest justices. The ones appointed by President Obama, Justices Sonia Sotomayor and Elena Kagan, have agreed 94 percent of the time. The members of the court appointed by President George W. Bush, Chief Justice John G. Roberts Jr. and Justice Samuel A. Alito Jr., have agreed 93 percent of the time.

The tendency is less marked among justices on the bench longer. President Bill Clinton's nominees, Justices Ruth Bader Ginsburg and Stephen G. Breyer, were less likely to agree, at 88 percent. And President Ronald Reagan's appointees, Justices Antonin Scalia and Anthony M. Kennedy, have agreed just 82 percent of the time.

In their public appearances, the justices often complain that the press focuses on closely divided cases and not on the many unanimous ones. The court is indeed often united, and it will end this term with unanimous decisions in more than half of its cases. Over the past four terms, even the members of the court least likely to agree voted together 66 percent of the time.

The table above shows how often each Supreme Court justice agreed with each of the others in the last four terms. Details on individual justices follow.

Whom Justice Kennedy agreed with Justice Kennedy sits at the court's ideological center. As such, he is the only justice who agrees with each of his colleagues at least 76 percent of the time. But his rates of agreement also indicate that he tilts to the right, agreeing with the four more liberal justices no more than 81 percent of the time and with the four more conservative justices at least 82 percent of the time. He is especially apt to vote with the newest conservatives, Chief Justice Roberts, at 88 percent, and Justice Alito, at 86 percent.

Whom Justice Thomas agreed with Justice Thomas was the member of the court most likely to disagree with its liberal wing, but Justice Alito was close behind.
