While the Mann Act has never been repealed, it has been amended and altered since its initial passing. The Mann Act continued essentially unchanged until 1978 amendments that expanded coverage to issues around child pornography and exploitation. Most recently, in 1986, the Mann Act was significantly altered to make the whole Act gender neutral and to redress the specific ambiguous phrasing that had enabled decades of unjust applications of the Act. With the 1986 amendments, the Mann Act outlaws interstate or foreign transport of "any person" for purposes of "any sexual activity for which any person can be charged with a criminal offense." Prior to the Supreme Court ruling in "Lawrence v. Texas" (2003), sodomy was illegal in many states which left open the possibility of prosecution under the Mann Act of consenting adult couples, especially gay couples, though there is no record of such enforcement actions. Since 1978 most prosecutions have been related to child abuse and child trafficking cases.
