Case Law

The word "case" is often used interchangeably with "opinion" or "decision." It is the written resolution of the issues in dispute, written by a judge or a panel of judges. It is not a jury verdict. Juries decide facts; judges decide law.

Cases come from courts. A generic court system consists of (1) trial courts, (2) intermediate appellate courts, and (3) the appellate court of last resort, which is often called the "Supreme Court." There are also specialized federal courts (Bankruptcy, Tax, etc.).

On the state level, reported, or published, opinions generally come from the appellate courts – not the trial courts. On the federal level, some trial court cases are reported. Remember that in a jury trial, there is nothing to "report" except a verdict.

The full text of published opinions are printed in sets of books called reporters. Only those opinions that the court deems to have precedential value are published. Judges use these published cases to decide later cases involving similar facts or issues. When a court first releases an opinion, it is usually published as a single case in a pamphlet known as a "slip opinion." Multiple opinions are collected and published in soft-bound pamphlets called "advance sheets." Advance sheets are later replaced by bound volumes, known as "reports" or "reporters." The pagination in the advance sheets and the bound volumes is identical. A list of the major reporters held by the Gallagher Law Library can be found at http://lib.law.washington.edu/ref/repdig.htm.

Official reporters are published under the authority of the legislature or court, and usually printed by the government. The official reporter for the U.S. Supreme Court is United States Reports. Washington State has a pair of official reports: Washington Reports 2d (cases from the Washington Supreme Court) and Washington Appellate Reports (cases from the Washington Courts of Appeal). These are prepared by the state Reporter of Decisions, but printed and sold by a commercial publisher (West Group).

Unofficial reporters are printed by private publishers (such as West Group) with or without authority from the legislature or court. The National Reporter System, developed by West, covers both federal and state courts, and is tied in with the West Digest System, a case finding aid. There are two major unofficial reporters for the U.S. Supreme Court, and one each for the Federal Courts of Appeals and the Federal District Courts. These lower court reports are the only option for these opinions; there are no official print reporters.

Unpublished opinions can sometimes be found online or in topical newsletters or looseleaf services.
