This Essay examines the possible justification for providing less than full (fair market value) compensation for expropriation. One obvious justification applies in cases of public measures, where the burden is deliberately distributed progressively, namely, where redistribution is the desired goal of the public action or, at least, one of its primary objectives. Beside this relatively uncontroversial category, two other explanations are often raised: that partial compensation is justified by reference to the significance of the public interest, even if it is not redistributive, and that it can serve as a means for adjusting the amount of the compensation to the specific circumstances of the case. This Essay criticizes both justifications, arguing that the former is normatively impoverished while the latter affronts the rule of law. The notion of partial and differential compensation, however, can serve as a powerful tool for developing a nuanced expropriation doctrine that serves important property values, and also targets the potentially regressive effects of a uniform rule of full market value. The proposed doctrine draws careful, rule-based distinctions between types of injured property (fungible vs. constitutive) and types of benefited groups (local communities vs. the broader society).
