Everyone knows what my favorite case is: Griswold v. Connecticut. The court held "Connecticut law criminalizing the use of contraceptives violated the right to marital privacy."
Griswold is one of those pivot-law cases. It held that although there is no explicit "right to privacy" in the Constitution, several of the amendments are clear indicators that the writers assumed privacy from government intrusion within one's own body and property as a given. The case is almost universally loathed among right-wing commentators because it restrained the government from policing the private conduct of its citizens. Based on Griswold, we got Roe v. Wade, Eisenstat v. Baird which allowed unmarried people to buy contraceptives, and Lawrence v. Texas which legalized homosexual conduct in the privacy of one's own home.
