John McLean, Darrington v. Branch of the Bank of the State of Alabama…
“ A bill of credit emanates from the sovereignty of the State. It rests for its currency on the faith of the State pledged by a public law. The State cannot be sued ordinarily on such bill, nor its payment exacted against its will. There is no fund or property which the holder of the bill can reach by judicial process. Such an instrument is altogether different, in form and in substance, from the notes issued by the branch bank at Mobile. The fact that the State of Alabama may be sued by one of its citizens does not alter the case. ”
