Multimedia.pngClick here to see the Martin-Quinn Scores, an overview of the ideological positions of Supreme Court justice since 1937 in a website created by faculty members at the University of California Berkeley School of Law.

As reported in the New York Times (July 25, 2010), Harold J. Spaeth. a professor at Michigan State University, has coded Supreme Court rulings since 1937 as conservative or liberal.
  • The most liberal justices between 1937 and 2009 were Thurgood Marshall (21% conservative votes) and William O. Douglas
  • The most conservative were Clarence Thomas (82% conservative votes) and William Rehnquist.
  • According to this measure, four of the most conservative justices since the 1930s are currently serving on the Court (Thomas, Samuel Alito, Antonin Scalia and John Roberts).

Study Challenges Supreme Court's Image as Defender of Free Speech examines the Roberts Court record on First Amendment cases. It contends that the Roberts Court is ruling in favor of free speech at a lower rate than the three previous courts under Chief Justices Rehnquist, Burger, and Warren.

United States Court of Appeals

Before cases reach the Supreme Court they must make their way through the other courts in the US. The US court of appeals hears cases involving patent laws and financial situations. The 94 U.S. judicial districts are organized into 12 regional circuits, each of which has a United States court of appeals. Appeals are formal requests for change in an official decision usually made by defense attorneys to lessen the punishment of their clients.

United States District Courts

US district courts take all matters of law and is the starting place of any case criminal or civil. The district courts are the trial courts in the federal system and can hear any case but within limits set by Congress and the Constitution. There are 94 federal judicial districts, including at least one district in each state, the District of Columbia and Puerto Rico. District courts are the local courts in cities and towns all over America. Every day across the country hundreds of people are selected for jury duty which take place in district courts. People have to report to jury duty because it is an important part of the legal system. Citizens of the US have the right to a jury trial. If people disregard jury duty they can be brought into court and even jailed because it is illegal to miss jury duty.

Bankruptcy Court

Bankruptcy court is actually part of the federal courts. The federal courts hear bankruptcy cases in each of the 94 jurisdictions across the country. Bankruptcy laws help people who can no longer pay their creditors. These courts help people get a fresh start by liquidating their assets to pay their debts, or by creating a repayment plan. Bankruptcy laws also protect and help troubled businesses through similar means. These procedures are covered under Title 11 of the United States Code (the Bankruptcy Code).

Courts of the Commonwealth of Massachusetts
State courts like the ones in Massachusetts are set up like federal courts but have different laws depending on the state. Massachusetts has district courts, a supreme court, bankruptcy courts and appeals courts.
