Which Supreme Court ruling first established that Americans had a right to privacy concerning the use of contraception?

This 1896 Supreme Court decision upheld racial segregation under the "separate but equal" doctrine. It primarily focused on civil rights issues related to race, making no reference to privacy rights or contraception, and therefore is irrelevant to the question.

Decided in 1978, this case dealt with affirmative action and racial quotas in university admissions. It addressed issues of equality and discrimination rather than privacy rights or contraception, making it unrelated to the context of the question.

In 1966, this ruling established the Miranda rights, requiring that individuals taken into police custody be informed of their rights to silence and legal counsel. While significant for criminal procedure, it does not pertain to issues of privacy regarding contraception.

This 1992 ruling reaffirmed the right to have an abortion while allowing states to impose certain restrictions. Although it built upon the principles of privacy established in earlier cases, it did not originate the right to privacy concerning contraception, which was first articulated in Griswold v. Connecticut.
