Charles Evans Hughes, Russo-Chinese Bank v. National Bank of Commerce of Seattle Washington…
“ Immediately following the words quoted, the court said:'It is a general rule of law that where collateral security is received for a debt with power to convert the security into money, this is specifically applicable to the payment of such debt; the same person being the party to pay and receive, no act is necessary and the law makes the application. If the proceeds equal or exceed the amount of the debt it is de facto paid; no action would lie for it, and proof of these facts would support the defense of payment. ”
