When looking at Justice Scalia’s approach to the Fourth Amendment, most would say he was an originalist and a textualist. Justice Scalia himself would like to explain, “I’m an originalist and a textualist, not a nut.” Although originalism and textualism were often prevalent in his Fourth Amendment decisions, even more important to his decision-making was his disdain for judicial activism. To limit judicial discretion, Justice Scalia frequently opted to impose bright-line rules rather than vague standards. This is apparent not only within his jurisprudence as a whole, but also specifically in his Fourth Amendment decisions.

This Article examines Justice Scalia’s effort to limit judicial discretion through the lens of the debate between rules and standards. It is the first article to situate Scalia’s goal of limited discretion within the framework of the debate between rules and standards, as well as the first to discuss this issue specifically with respect to his Fourth Amendment decisions. Rules are binding directives that leave little room for considering the specific facts of any given situation. Critics argue that they tend to be over- or under-inclusive, but the value of rules is that by taking power away from the decisionmaker, they limit judicial discretion. Further, some argue that rules promote democracy because they properly leave the power to make decisions based on politics or value judgments to the legislature. On the flip side, proponents of standards argue that standards produce judgments that are less arbitrary and more substantively fair because they allow decisionmakers to consider all of the relevant facts and circumstances of the case.
