This document summarizes an article that examines how precedent is created and applied by courts over time through a close study of 200 Illinois cases from 1876 to 1985 regarding antagonistic defenses. The article finds that precedent was unintentionally distorted through a process where words were taken out of context by lawyers, injected into case law by courts, and then repeated by later courts who lost the original meaning. This process questions whether the judicial system can truly be said to be based on precedent and stare decisis. The document also reviews the ongoing debate between traditional legal scholars and political scientists over the degree to which judicial decisions are influenced by legal factors versus extra-legal influences like ideology.
