United States v. Guest
United States Supreme Court case

United States v. Guest, 383 U.S. 745 (1966), is a landmark decision of the US Supreme Court authored by Justice Potter Stewart, in which the court extended the protection of the 14th Amendment to citizens who suffer rights deprivations at the hands of private conspiracies, where there is minimal state participation in the conspiracy. The Court also held that there is a Constitutional right to travel from state to state.
While the majority avoided the question of whether Congress, by appropriate legislation, has the power to punish private conspiracies, Justice Clark, writing in concurrence, asserted that "there now can be no doubt that the specific language of §5 empowers the Congress to enact laws punishing all conspiracies - with or without state action - that interfere with 14th Amendment rights." Justice Hugo Black and Justice Abe Fortas joined Clark's concurrence.
Background
The case arose out of the killing of Lemuel Penn, an African-American reserve officer who was returning from active duty training to Washington, D.C., where he was Assistant Superintendent of Washington, D.C. public schools. He was traveling north in a car with two other black Reserve officers when he was shot and killed on a bridge, just nine days after the Civil Rights Act of 1964 passed.
The murder happened in Madison County, Georgia, and the alleged killers were charged but acquitted there by an all-white jury. The federal indictment in question arose after the acquittal. In District Court, the six defendants successfully "moved to dismiss the indictment on the ground that it did not charge an offense under the laws of the United States," according to the case. The Supreme Court reversed.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 20, 2026. The linked authority identifier is Q7893307. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1966 and 1964.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
