Contract Law Module: Doctrine of Consideration

Introduction

  • Focus on the Doctrine of Consideration.
  • Consideration is essential for contract formation.
  • "No consideration, no contract".

Definition of Consideration

  • Cited from Curry v. Misa:
    • A valuable consideration can be a right, interest, profit, or benefit to one party, or a forbearance, detriment, loss, or responsibility by the other party.
  • Consideration is a benefit to one party or a detriment to the other exchanged for a promise.
  • Courts' View:
    • Courts do not usually assess the adequacy (quality or quantity) of consideration.
    • Even nominal consideration (e.g., a "peppercorn") suffices.

Characteristics of Consideration

  • Must be mutually related to the promise given.
  • Must be the motive for the other party's promise.
  • Must be given in response to that promise.

Nature of Consideration

  • Legal Benefit or Detriment:
    • A tangible benefit is not necessary.
    • Example: Hamer v. Sidway.
      • Uncle promised $5,000 for the nephew abstaining from certain behaviors.
      • Nephew’s abstention was a legal detriment despite no material benefit to the uncle.

Illusory Consideration

  • Occurs when one party does not actually provide consideration despite appearances.
  • Example: Tobias v. Dick
    • Tobias had exclusive rights but did not promise to sell machines.
    • Court found no contract formed.

Implied Terms and Consideration

  • Courts might imply terms to validate contracts.
  • Example: Wood v. Lucy, Lady Duff-Gordon
    • Wood’s promise to use reasonable efforts implied.
    • This made the contract bilateral.

Valid Consideration Requirements

  • Must be requested by the promisor.
  • Must not be an act or benefit already performed ("past consideration").
    • Example: Natalie buying lunch.

Exceptions to Past Consideration

  • Pao On Test:
    • Act performed at promisor’s request.
    • Understanding that the act would be compensated.
    • Example: Charlie driving to the mall.

Consideration in Contract Amendments

  • Amendments require new consideration.
  • Example: Gilbert Steel v. University Construction
    • Gilbert Steel’s demand for higher price lacked new consideration as they were already obligated to deliver at the original price.
