Rule 302 Applying Federal Law to Presumptions in Civil Cases

When a civil case involves a claim or defense that comes from federal law, federal rules decide how much weight a presumption carries. A presumption is a legal assumption the law makes until someone proves otherwise. For example, if federal law says a certain fact is presumed true, federal rules decide what that presumption actually does in court and how much evidence someone needs to challenge it.

This matters because state and federal courts do not always treat presumptions the same way. Some treat a presumption as strong evidence that shifts the burden of proof to the other side. Others treat it as something that simply disappears once any evidence contradicts it. This rule makes sure that when the underlying claim or defense is based on federal law, courts use the federal approach instead of state rules, even if the case is being handled in a state court setting.

In short, this rule keeps things consistent. If your case depends on a federal law, the federal rules about presumptions apply, no matter where the case is being heard.
