James Clark McReynolds,
New York Company v. United States…
“ And as appellant voluntarily accepted and performed the service with knowledge of what the United States intended to pay, it cannot now claim an implied contract for a greater sum. It may be that any railroad by failing to carry the mails would incur the hostility of those living along its lines and as a consequence suffer serious financial losses; but the fear of such results certainly does not amount to compulsion by the United States and cannot constitute the basis of a justiciable claim against them for taking property. ”
