Lon Fuller and William Perdue’s The Reliance Interest in Contract Damages: 1, 46 Yale L.J. 52 (1936), is best known for its analytic claim that there are three basic measures of contract damages: restitution, reliance and expectation. Also familiar are the article’s normative and descriptive theses: that that the reason for judicial intervention decreases as one moves from restitution to reliance and then from reliance to pure expectation, and that in many cases courts calculate damages with an eye to compensating reliance rather than fulfilling the promisee’s expectation. Often overlooked is the article’s methodological claim, which Fuller and Perdue label “the divergence of measure and motive” (66). “Measure” here stands for the remedial measure that attaches to the violation of a legal duty and “motive” designates the duty’s purpose or raison d’être. The divergence of measure and motive claims that the tie between rights and remedies is looser than is commonly thought. It follows that remedies are the wrong place to start when constructing an interpretive theory of legal duties.
Fuller and Perdue offer two arguments. First, practical considerations such as difficulties in proof or measurement often recommend an alternative remedy. “[E]ven where it is reasonable to suppose that a single interest furnishes the exclusive raison d’être of legal intervention it is still possible for reasons of convenience and certainty the court may choose a measure of recovery which differs from that suggested by the interested protected” (66-67). An example can be found in Fuller and Perdue’s explanation of the expectation measure as designed to protect the nonbreaching party’s reliance interest. The expectation measure captures opportunity costs, which are often difficult to prove. And the expectation measure facilitates reliance by dispensing with its proof. More generally, administrative costs, problems of proof, the possibility of error and other practical pressures can all push remedies in directions that might not correspond to the best explanations of the associated duties.
