Turner v. Safley, 482 U.S. 78 (1987), was a U.S. Supreme Court decision involving the constitutionality of two Missouri prison regulations. One of the prisoners' claims related to the fundamental right to marry, and the other related to freedom of speech (in sending/receiving letters). The court held that a regulation preventing inmates from marrying without permission violated their constitutional right to marry because it was not logically related to a legitimate penological concern, but a prohibition on inmate-to-inmate correspondence was justified by prison security needs.
