With the 1884 Supreme Court ruling in "Juilliard v. Greenman", the "Supreme Court ruled that Congress had the right to issue notes to be legal tender for the payment of public and private debt. Legal-tender notes are treasury notes or banknotes that, in the eyes of the law, must be accepted in the payment of debts." The ruling in the Legal Tender Cases (which include "Juilliard v. Greenman") led later courts to "support the federal government's invalidation of gold clauses in private contracts in the 1930s."
