The Development of a Legal Rule: The Federal Common Law of Public Nuisance

Scholars from across disciplinary lines are interested in understanding legal development. One impediment to the quest for a systematic explanation has been measures of legal change. Indicators like whether a court overturns an earlier ruling capture one facet of legal change but fail to capture the full range of courts' actions to develop legal doctrine. I introduce an alternative measure of legal change here—one based on Levi's (1949) focus on whether factual circumstances are or are not encompassed by the law. I use the U.S. Courts of Appeals decisions on the federal common law of public nuisance to illustrate this measure. Utilizing a multinomial logit model to explore the appellate judiciary's decisions to develop this legal doctrine, I find that the judges' decisions to develop the federal common law are explained by the judges' policy preferences; the litigation environment consisting of party resources, attorney experience, and amicus support; as well as the broader political context of public opinion and Supreme Court rulings.
