Refusal to testify in a civil case
While defendants are entitled to assert that right, there are consequences to the assertion of the Fifth Amendment in a civil action.
The Supreme Court has held that the Fifth Amendment does not forbid adverse inferences against parties to civil actions when they refuse to testify in response to probative evidence offered against them.
Baxter v. Palmigiano, 425 U.S. 308, 318 (1976). [A]s Mr. Justice Brandeis declared, speaking for a unanimous court in the Tod case, Silence is often evidence of the most persuasive character. Id. at 319 (quoting United States ex rel. Bilokumsky v. Tod, 263 U.S. 149, 153-154 (1923)). Failure to contest an assertion...is considered evidence of acquiescence...if it would have been natural under the circumstances to object to the assertion in question. Id. (quoting
United States v. Hale, 422 U.S. 171, 176 (1975)).
In
Baxter, the state was entitled to an adverse inference against Palmigiano because of the evidence against him and his assertion of the Fifth Amendment privilege.
