Ideological leanings of United States Supreme Court justices
Updated: Wikipedia source
The Supreme Court of the United States is the country's highest federal court. The Court has ultimate—and largely discretionary—appellate jurisdiction over all federal courts and state court cases involving issues of U.S. federal law, plus original jurisdiction over a small range of cases. The nine Supreme Court justices base their decisions on their interpretation of both legal doctrine and the precedential application of laws in the past. In most cases, interpreting the law is relatively clear-cut and the justices decide unanimously; however, in more complicated or controversial cases, the Court is often divided. In modern discourse, the justices of the Court are often categorized as having conservative, moderate, or liberal philosophies of law and of judicial interpretation. It has long been commonly assumed that justices' votes are a reflection of their judicial decision-making philosophy as well as their ideological leanings, personal attitudes, values, political philosophies, or policy preferences. A growing body of academic research has confirmed this understanding, as scholars have found that the justices largely vote in consonance with their perceived values. Analysts have used a variety of methods to deduce the specific perspective of each justice.
