DeVillier v. Texas, 601 U.S. 285 (2024), was a case that the Supreme Court of the United States decided on April 16, 2024.

Because the case touched on whether or not the 5th Amendment is self-executing, the case had implications for Trump v. Anderson and whether or not section 3 of the Fourteenth Amendment to the United States Constitution is self-executing,[3][4] though ultimately the Anderson decision was announced before DeVillier.

[9] Justice Clarence Thomas wrote the unanimous opinion of the court, holding that DeVillier should be allowed to pursue his claim through the statutory mechanism articulated under Texas law.

I’m pleased the Supreme Court agreed with us unanimously that citizens should sue under Texas law.”[10]The Institute for Justice, which represented DeVillier, criticized Paxton's statement, saying: "If Texas had won today, the Supreme Court would have affirmed [the Fifth Circuit's] ruling.

Instead, the Court did the opposite: Today’s ruling makes clear that Texas can be sued under the Fifth Amendment and that the claims Texas wanted thrown out will instead go to trial in that same federal district court—in other words, after Texas spent untold amounts of time and taxpayer dollars trying to get Richie’s Fifth Amendment claims dismissed, Richie will get to litigate his Fifth Amendment claims.
