Eastern Building and Loan Assn. v. Ebaugh

Background

A New York association (a company) made a promise that a particular share of stock would mature in seventy‑eight months. A buyer in South Carolina relied on that promise, subscribing for the stock after seeing circulars and hearing agent assurances. The company later disputed the promise, pointing to New York decisions it said treated certificate maturity as only an estimate and argued the company lacked authority to fix a maturity date. The buyer sued in South Carolina, and the state trial and supreme courts found the company had indeed promised a definite maturity and that the buyer had performed in good faith.

Reasoning

The central question was whether the South Carolina courts erred in applying New York law and in finding the promise binding. The Supreme Court explained that what another State’s law means is a matter of fact that must be proved, and that a state court’s factual findings about another State’s law are conclusive on review here. The Court relied on prior decisions and confirmed that if a corporation makes an agreement and accepts the other party’s performance, it cannot avoid the promise by later claiming lack of authority.

Real world impact

The decision leaves the South Carolina judgment in place and makes clear that trial-court fact findings about another State’s law are binding on higher review. That protects individuals who rely on clear promises from companies and limits how much a company can escape contract obligations by invoking technical limits on its powers. This ruling affirms the state-court result rather than announcing a new national constitutional rule.
