United States v. Clark
Argued January 9, 10, 1906
Decided March 5, 1906
200 U.S. 601
The rule that this Court will not disturb findings of fact where both the circuit court and the circuit court of appeals have concurred should not be departed from except in a very clear case, especially when those findings are against a charge of fraud in an effort to overthrow a patent of the United States.
In order to overthrow a patent on charges of fraud on the part of the entryman and knowledge thereof on the part of a purchaser, the proof must be clear, and fraud or knowledge of fraud in the entry will not be inferred from a merely suspicious circumstance; the purchaser is not bound to hunt for grounds of doubt. United States v. Detroit Timber & Lumber Co., ante, p. 200 U. S. 321, followed.
The facts are stated in the opinion.
