Tot v. United States

In Tot v. United States, 319 U.S. 463 (1943), the United States Supreme Court held that the "controlling" test for determining the validity of a statutory presumption was "that there be a rational connection between the facts proved and the fact presumed" (Id. at 467). The Court stated: "Under our decisions, a statutory presumption cannot be sustained if there be no rational connection between the fact proved and the ultimate fact presumed, if the inference of the one from proof of the other is arbitrary because of lack of connection between the two in common experience. This is not to say that a valid presumption may not be created upon a view of relation broader than that a jury might take in a specific case. But where the inference is so strained as not to have a reasonable relation to the circumstances of life as we know them it is not competent for the legislature to create it as a rule governing the procedure of courts." (Id. at 467-468.)
