Date of Decision

28 June 1978


Until United States Trust Co. v. New Jersey (1977), there had been no significant Contract Clause challenges before the Court since the 1930s. Allied Structural Steel Co. v. Spannaus, the next Contract Clause case of note after United States Trust, strengthened the impact of the clause and proved that it was not, in Justice Stewart's words, "a dead letter."


Expectations that Spannaus would inaugurate a new era for the Contract Clause proved to be short-lived. In Exxon Corp. v. Eagerton (1983), the Court restricted the application of its Spannaus ruling to statutes whose "sole effect" was "to alter contractual duties." Four years later, in Keystone Bituminous Coal Association v. DeBeni (1987), the Court rejected a Contract Clause challenge to a Pennsylvania law.
