“ If upon contracts of such a nature an action against the government could be maintained in the Court of Claims, whenever an agent should deem himself entitled to greater or different compensation than that awarded to him, the whole service in any case, and the manner of its discharge, with the details of dealings with individuals and officers, might be exposed, to the serious detriment of the public. ”

“ Much greater reason exists for the application of the principle to cases of contract for secret services with the government, as the existence of a contract of that kind is itself a fact not to be disclosed. ”

“ It may be stated as a general principle, that public policy forbids the maintenance of any suit in a court of justice, the trial of which would inevitably lead to the disclosure of matters which the law itself regards as confidential, and respecting which it will not allow the confidence to be violated. ”
