Ward Hunt, Little Rock v. National Bank — Opinion of the Court
“ If it derived a new validity from the surrender of an old debt of a disputed character, it is to be observed that all of the debt was equally given up. New bonds were issued for a portion, but all of the debt was surrendered. It was the surrender of what was claimed to be a legal debt, and the creating a new obligation thereby, that is said to create the liability. If a city has power to bind itself by substituting a new liability for a cancelled one, it may do so by any instrument of acknowledgment which affords sufficient evidence of a debt. ”
