The correct answer is: "the right to marital privacy".
Griswold v. Connecticut was a landmark decision by the US Supreme Court, issued in 1965, that has governed since then the access to contraception. The case was related to a law existing in Connecticut (Comstock law) that prohibited taking drugs to prevent conception. In opposition, the Supreme Court declared that the law was invalid because it violated the 'right to marital privacy' by which every person has the right to decide over his/her intimate practices.
