Case Brief Summary & Legal Analysis

tl;dr: An architect quit a project and refused to finish his work unless paid more. The court held the owner’s promise of extra pay was unenforceable because the architect was already contractually obligated to perform the work.

Legal Significance: This case is a foundational example of the pre-existing duty rule, holding that a promise to pay more for performance that a party is already contractually obligated to render is unenforceable for lack of consideration.

Case Facts & Court Holding

Key Facts & Case Background

Edmund Jungenfeld, an architect, entered into a contract with Wainwright Brewing Co. to design plans and supervise the construction of a new brewery. His compensation was to be a five percent commission on the total cost of the buildings. The contract did not include work on the refrigerator plant to be installed within the brewery. The defendant awarded the contract for the refrigerator plant to a competitor of a company in which Jungenfeld was president. In response, Jungenfeld ceased all work, removed his plans, and abandoned the project, in breach of his contract. The defendant was in great haste to complete the brewery and would have suffered significant financial loss from the delay of finding a new architect. Under these circumstances, the defendant promised to pay Jungenfeld an additional five percent commission on the cost of the refrigerator plant if he would resume his duties. Jungenfeld agreed, completed his original supervisory work, and his estate later sued to enforce the promise for the additional commission.
