This paper presents a simple framework for analyzing a hierarchical system
of judicial auditing. We concentrate on (what we perceive to be) the two pr
incipal reasons that courts and/or legislatures tend to scrutinize the deci
sions of lower-echelon actors: imprecision and ideological bias. In compari
ng these two reasons, we illustrate how each may yield systematically disti
nct auditing and reversal behaviors. While auditing for imprecision tends t
o bring about evenhanded review/reversal reversal, auditing for political b
ias tends to be contingent on the first mover's chosen action. Examples of
these tendencies can be found in a number of legal applications, including
administrative law, constitutional law, and interpretive theories of jurisp
rudence. Our analysis also suggests that political "diversity" among initia
l decision makers tin addition to its other laudable goals) may be an impor
tant and generally underappreciated means for economizing on judicial admin
istrative costs.
