ARTICLE III. PRESUMPTIONS IN CIVIL CASES
FRE 301: Presumptions in Civil Cases Generally
In a civil case, unless a federal statute or these rules provide otherwise, the party against whom a presumption is directed has the burden of producing evidence to rebut the presumption. But this rule does not shift the burden of persuasion, which remains on the party who had it originally.
FRE 302: Applying State Law to Presumptions in Civil Cases
