Summary

William Johnson Farrar v. United States — Opinion of the Court

Unless the bond sued on was authorized by some act of congress, it is not obligatory. Although the power of making contracts is inherent in every sovereignty, and may be exercised in every government which has a constituted agent authorized to exert that power, and an existing code of laws ascertaining the obligation of such contracts; yet the United States not having by the constitution of their government committed the exercise of this attribute of sovereignty to any officer or agent, it cannot be exercised in the absence of any expression of the legislative rule.
