 As noted earlier, the political economy strand of economic analysis of law itself contains two strands that are in tension with each other. On the one hand, the radical political economy strand seeks only to explain legal phenomena rather than to prescribe either the structure of legal institutions or the content of particular legal rules. One might find within this strand of political economy a positive theory of adjudication but not a normative theory. Indeed, the positive theory advanced argues that judges seek to promote their interests. Usually, these interests are defined as policy interests, that is, an interest to promote particular policies.
