Final answer:
The right to privacy was first enunciated by the U.S. Supreme Court in the 1965 case Griswold v. Connecticut. While not explicitly stated in the Constitution, it is derived from several amendments and was conceptually introduced by Warren and Brandeis in 1890.
Step-by-step explanation:
The idea that the Constitution guarantees a right to privacy was first enunciated in the landmark case Griswold v. Connecticut in 1965. This case addressed the issue of contraception for married couples and was later extended to unmarried individuals. While the US Constitution does not explicitly mention a right to privacy, the Supreme Court has recognized it as implicit within the protections of several amendments.
The seminal concept of a legal right to privacy in the United States was advanced by Samuel D. Warren and Louis Brandeis in their 1890 law review article "The Right to Privacy". The Supreme Court rulings in cases like Pierce v. Society of Sisters, Roe v. Wade, and Lawrence v. Texas expanded this interpretation, establishing privacy as a fundamental right connected to personal liberty and self-determination.
