On March 1, 2016, the Supreme Court decided Lockhart v. United States. Petitioner Avondale Lockhart pleaded guilty to possessing child pornography. Because Lockhart had a prior state-court conviction for first-degree sexual abuse involving his adult girlfriend, his presentence report concluded that he was subject to a 10-year mandatory minimum sentence enhancement, which is triggered by prior state convictions for crimes “relating to aggravated sexual abuse, sexual abuse, or abusive sexual conduct involving a minor or ward.” Lockhart argued that the limiting phrase “involving a minor or ward” applied to all three state crimes, so his prior conviction did not trigger the enhancement. Disagreeing, the District Court applied the mandatory minimum. The U.S. Court of Appeals for the Second Circuit affirmed. -- By a vote of 6-2, the U.S. Supreme Court affirmed the judgment of the Second Circuit. Justice Sotomayor delivered the opinion of the Court, holding that the phrase “involving a minor or ward” in §2252(b)(2) modifies only “abusive sexual conduct.” Thus, Lockhart’s prior conviction for sexual abuse of an adult was encompassed by §2252(b)(2) and the 10-year mandatory minimum applied. -- Justice Sotomayor’s majority opinion was joined by the Chief Justice and Justices Kennedy, Thomas, Ginsburg, and Alito. Justice Kagan filed a dissenting opinion in which Justice Breyer joined. -- To discuss the case, we have Erin Sheley, who is Assistant Professor at University of Calgary Faculty of Law.
