58 . Which Supreme Court case invalidated a state law prohibiting the use __

## Step 1<br />The question is asking for the Supreme Court case that invalidated a state law prohibiting the use of contraceptives. This is a significant event in the history of the United States, as it marked a shift in the interpretation of the Constitution regarding the right to privacy.<br /><br />## Step 2<br />The Supreme Court case that fits this description is Griswold v. Connecticut. This case was a landmark decision by the United States Supreme Court that established the constitutional right to privacy.<br /><br />## Step 3<br />The case involved a Connecticut law that prohibited the use of contraceptives. The Supreme Court ruled that this law violated the "right to marital privacy". This right is not explicitly mentioned in the Constitution, but the Supreme Court interpreted it to be protected by the "penumbras" and "emanations" of other constitutional protections.<br /><br />## Step 4<br />The Supreme Court's decision in Griswold v. Connecticut set a precedent for future cases involving privacy rights. It established that the right to privacy is a fundamental right protected by the Constitution, and it laid the groundwork for the later case of Roe v. Wade, which extended this right to abortion.
