This legislation seeks to protect and promote individual rights and privileges guaranteed by the United States Constitution for current and future generations. It establishes that the U.S. Constitution and its laws are the supreme law of the land, and that the role of elected officials is to secure these liberties. The bill explicitly prohibits any United States court, judge, magistrate, administrative body, or other federal instrumentality from recognizing or enforcing any foreign law , religious law, custom, or practice that is in conflict or incompatible with the U.S. Constitution and its promulgated laws. The bill defines "foreign law" as any law from outside the U.S. that does not protect equivalent individual rights and liberties, and "religious law, custom, or practice" as any law implementing a religious system or ethnic custom. It specifically lists examples of incompatible practices, including prejudicial treatment of women or minorities, prohibition of speech or religious freedom, plural or forced marriages, violence against women and children, and cruel punishments like amputation or female genital mutilation. Furthermore, U.S. adjudicative bodies are barred from enforcing contractual provisions based on such laws, recognizing foreign decisions that applied them, or dismissing cases if an alternative forum would deny a litigant's constitutional rights.
