Moral turpitude

Moral turpitude is a legal concept in the United States, and until 1976 in Canada, that refers to “an act or behavior that gravely violates the sentiment or accepted standard of the community”. This term appears in U.S. immigration law beginning in the 19th century. Moral turpitude laws typically deal with legal, judicial, and business related transgressions. Moral turpitude laws should not be confused with laws regarding social morality, violations of which are more commonly called public order, morality, decency, and/or vice crimes.
