Lawrence v. Texas, 539 U.S. 558 (2003), was a landmark decision of the U.S. Supreme Court in which the Court ruled that U.S. laws prohibiting private homosexual activity, sodomy, and oral sex between consenting adults are unconstitutional. The Court reaffirmed the concept of a "right to privacy" that earlier cases, such as "Roe v. Wade", had found the U.S. Constitution provides, even though it is not explicitly enumerated. The Court based its ruling on the notions of personal autonomy to define one's own relationships and of American traditions of non-interference with private sexual decisions between consenting adults.
