Rufus Wheeler Peckham, Lalone v. United States — Opinion of the Court
“ A mere preponderance of evidence, which at the same time is vague or ambiguous, is not sufficient to warrant a finding of fraud, and will not sustain a judgment based on such finding. The rule obtains in cases of alleged fraudulent representations made to an officer of the government, upon the faith of which the officer has issued a patent, or done any other official act upon which the rights of the party making the misrepresentations may be founded. ”
