Mackenzie v. Hare, 239 U.S. 299 (1915), is a United States Supreme Court case that upheld Section 3 of the Expatriation Act of 1907, which dictated that all American women who voluntarily married an foreign alien renounced their American citizenship. While the statute has since been repealed, this case remains significant because of its precedent that Congress can designate acts which serve as implied voluntary renunciation of one's American citizenship.
