This paper evaluates the impact of a higher court articulating doctrine as either a “rule” or a “standard.” The legal doctrine we evaluate concerns police searches based upon information supplied by confidential informants. The Supreme Court’s Aguilar-Spinelli test was a rule, and its Illinois v. Gates “totality of the circumstances” test is a standard. Using a data set of circuit court opinions from 1951 to 1999, we compare circuit-level implementation of these two doctrines. The results suggest that rules are more effective than standards at constraining ideological voting in lower courts.
