A Statistical Look at the Supreme Court's 2009 Term

Whether a change in membership occurs or not, every Supreme Court term presents a unique set of controversies and decisions for legal scholars to examine. Herein, we offer a discussion of the Court's recently completed 2009-2010 term. Rather than analyzing specific opinions in detail (as many have already done), we generate a comprehensive statistical analysis of justice voting behavior for the term. In particular, we examine consensus and division on the Court, the ideological tenor of the term, voting alignments among the justices, the production of opinions, and the Court's overall ideological spectrum based on individual voting patterns. Ultimately, we also assess the ramifications of our findings for the future study of judicial behavior.
