More than half a century after the U.S. Supreme Court struck down a ban on the use of contraceptives by married couples based on a right to privacy, recent conservative nominees to that court, including Judge Amy Coney Barrett, still find it difficult to answer whether the case was correctly decided.

The Griswold v. Connecticut question is sensitive for those nominees because it is a foundational precedent for a substantive due process right to privacy, which became the basis for the landmark abortion decision in Roe v. Wade and other rulings, including the landmark same-sex marriage decision, Obergefell v. Hodges.
