Lacking Legislative Experience: The Impact of Changing Justice Backgrounds on Judicial Review

Abstract

Abstract Though once commonplace, presidents no longer nominate individuals with legislative experience to the U.S. Supreme Court. What difference does this shift make? Drawing on theories that connect judicial background characteristics to decision-making, I test whether legislative background impacts federal judicial review. Using nonparametric matching and almost 150 years of judicial review decisions, I find that, while such experience decreases the likelihood of striking down a law, the effect is small. By contrast, partisanship has a much stronger impact, with justices more likely to strike down laws when the enacting Congressional majority is a different party from their appointing president.
