Cohen v. New York City in Illinois Law

How Cohen v. New York City applies in Illinois: state-specific rules, key cases, and bar exam notes for Contracts.

State Approach

Illinois recognizes the validity of a unilateral contract as established in Cohen v. New York City. The state courts closely adhere to precedents that enforce such contracts when one party has performed an act in reliance upon the promise of another.

State Rule
In Illinois, a unilateral contract is enforceable when one party's performance has been accepted as consideration for the other party's promise, even without a formal acceptance.
Significant State Cases

Arnold v. Chicago Park District

The court upheld that a unilateral contract existed when a party fulfilled a specific act in reliance on the promise made in a public announcement.

Lobato v. Illinois Central Railroad

The holding emphasized that a plaintiff's reliance on a public promise can create an enforceable unilateral contract, reinforcing Cohen's principles.

Sullivan v. Barlow

The court found a unilateral contract enforceable where the plaintiff fulfilled the conditions set forth by the defendant's promise.

Comparison to Federal Law

Illinois law is generally aligned with federal principles regarding unilateral contracts, particularly under the Restatement (Second) of Contracts. However, Illinois courts emphasize the reliance element more than some federal rulings, which may allow for broader interpretation of consideration.

Bar Exam Note

Understanding unilateral contracts as illustrated in Cohen v. New York City is crucial for the Illinois bar exam, as it tests the enforceability of promises based on performance.
