This article examines the statistical distribution of amicus brief filings. The previous research on the distribution of amicus brief filings had examined the patterns of citation frequency in order to test three models. The current study tests these models in the context of amicus brief filings. The two primary results of the current study are presented. First, a power law distribution does provide improved fit over linear regression. Second, amicus brief filings are unrelated to the number of federal appellate citations received by an opinion.
