For decades, constitutional theorists have confronted the normative problems associated with judicial review by an
unelected judiciary; yet some political scientists contend that judicial review actually tends to promote majoritarian
interests. We evaluate the majoritarian nature of judicial review and test the political foundations that shape this
process. To do so, we construct a statute-centered data set of every important federal law enacted from 1949 through
2008 and estimate the probability of a law being challenged and subsequently invalidated by the Supreme Court. Our
methodological approach overcomes problems of selection bias and facilitates a test of judicial majoritarianism and the
mechanisms that drive that behavior. We find that the Court tends to invalidate laws with little support from elected
officials and that this pattern is primarily driven by the justices’ concern for congressional constraint during the
certiorari stage.
