I found this on a legal site:
When a party invokes the Fifth Amendment privilege against self-incrimination in a civil case, the court is permitted to instruct the jury that it may draw an adverse inference that the answer would have been against the party’s interest. Mitchell v. United States, 526 U.S. 314, 119 S. Ct. 1307, 143 L. Ed. 2d 424 (1999); Baxter v. Palmigiano, 425 U.S. 308, 318, 96 S.Ct. 1551, 47 L.Ed.2d 810 (1976); Farace v. Independent Fire Insurance Co., 699 F.2d 204, 210 (5th Cir.1983).
