American law schools use appellate court decisions to teach the implementation and progression of the law. Typically, the first case in a series will stand for the proposition that a plaintiff is entitled to a certain right. A later case demonstrates that a subsequent plaintiff is also entitled to the right. After a number of cases are presented, the student is expected to understand the law, policy, doctrine or test that applies to situations revolving around the right.
