Voting Bloc Analysis

Analyze how justices, or groups of justices ("blocs"), vote with or against each other. Once you select the first justice from the drop-down menu, a new selection box will appear with the names of justices who served with the first member you selected. You may than narrow the results to show cases pertaining to specific areas or topics, if desired. The search results provide the number of times the bloc of justices selected were together in the majority and the number of times they were together in the minority, or the number of times the selected bloc of justices voted against each other. This query includes all cases decided from 1941 to the current term.
