Ex Ante and Ex Post Control over Courts in the US States: Court Curbing and Political Party Influence

Abstract

Court curbing, proposed policy that attempts to “restrict, remove or otherwise limit” the power of the judiciary, occurs regularly and with considerable variation throughout the US states. I deviate from past studies, which consider court curbing as an ex post control mechanism, by focusing on ex ante controls of state courts – judicial selection rules and processes. I argue that levels of political party influence over judicial selection (before a judge is seated) alter the motivation to engage in court curbing after a judge is seated. I test this novel ex ante explanation with an original data set of court curbing and judicial selection from 2015 to 2018. Mixed results offer some support for my theory while opening new opportunities for study, particularly among partisan election systems.
