The Third-Party Doctrine vs. Katz v. United States

Cornell law professor Sherry F. Colb proposes revising the third-party doctrine in a way that reconciles two of the U.S. Supreme Court’s decisions that some critics view as conflicting. Colb suggests that, contrary to what most critics argue and what she herself has long assumed, the prior decision, Katz v. United States rather than the later one, United States v. White, is the anomaly.

Is a Gunshot Wound a Seizure?

Cornell law professor Sherry F. Colb comments on a case in which the U.S. Supreme Court will consider whether a police officer who shot and hit a fleeing suspect “seized” that suspect, thereby triggering the Fourth Amendment, even though the wounded suspect escaped the police. Colb explains some of the arguments and predicts an outcome that would affirm precedents and offers a compromise between competing constitutional concerns.

Should Police Need a Search Warrant to Chalk Tires and Discover Illegal Parking?

Cornell law professor Sherry F. Colb comments on a recent decision by the US Court of Appeals for the Sixth Circuit holding unconstitutional the use of chalk by police officers to track whether a parked car has remained longer than permissible. Colb considers whether the decision—which seems to faithfully apply the US Supreme Court’s decisions in Jones v. United States and Florida v. Jardines—falls short of the “reasonable expectation of privacy” test the Court established in Katz v. United States. Colb proposes a test that instead combines trespass, information-gathering, as well as some privacy interest in that information, arguing that such a test would better reflect the scope of the Fourth Amendment.

Collins v. Virginia: An Innocuous, Fourth Amendment Decision About Curtilage

Cornell law professor Sherry F. Colb comments on the US Supreme Court’s precedents recognizing, yet not clearly defining, “curtilage”—the area near one’s house that is constitutionally protected against warrantless searches by law enforcement. As Colb explains, the Court’s cases involving curtilage, including its recent decision in Collins v. Virginia leave many Fourth Amendment questions unanswered.

Carpenter and the Beginning of the End of Privacy

Cornell law professor Sherry F. Colb comments on the US Supreme Court’s recent decision in Carpenter v. United States, in which the Court held that the government must have a search warrant to obtain an individual’s cell-site location information (CSLI). Colb describes the Court’s holding and the dissenting opinions, and considers the Court’s minority (but growing) view that only property, and not privacy, is protected under the US Constitution—particularly when privacy rights encompass the right of a woman to obtain an abortion and the right of same-sex couples to engage in private, consensual sexual acts.
