Title 18 › Part II— CRIMINAL PROCEDURE › Chapter 223— WITNESSES AND EVIDENCE › § 3504
In any federal trial or other proceeding, if someone says a piece of evidence should be kept out because it was the direct result of an unlawful act or was gotten by taking advantage of an unlawful act, the other side must say whether that unlawful act happened. You do not have to turn over information about alleged unlawful acts that happened before June 19, 1968 unless that information is relevant to a current claim. Also, you cannot claim evidence is inadmissible because it was obtained by using an unlawful act that took place before June 19, 1968 if the event the evidence shows happened more than five years after the alleged unlawful act. Unlawful act here means using any electronic, mechanical, or other device (as defined in section 2510(5) of this title) in a way that breaks the U.S. Constitution, federal law, or rules made under those laws.
