Character Question on Cross
Selena Singh testified on direct about her company's occupancy reports. On cross-examination the opposing lawyer asked whether she had skimmed cash tips from staff and failed to report the income. Selena invoked the privilege because the question concerned only her character for truthfulness. The court sustained the objection and barred the inquiry.
Grand Jury Passphrase Demand
Federal agents subpoenaed Sophia Singh to enter a decryption passphrase for a server containing logs of alleged hacking. Sophia refused and moved to quash the subpoena. The court sustained the objection because entering the passphrase would communicate her knowledge and control of the server. That communication carried a real risk of tying her to criminal conduct.
Blood Draw After Arrest
Sydney Santos was arrested for driving while intoxicated. Officers directed a physician to draw her blood without a warrant. Sydney later moved to suppress the results on self-incrimination grounds. The court denied the motion because the blood sample was physical evidence rather than a testimonial communication.
Schmerber v. California384 U.S. 757 (1966)
Immunity Grant Before Testimony
Santiago Sanchez received a grant of use and derivative-use immunity before testifying before a grand jury. After the testimony the government prosecuted him using evidence developed independently of his statements. The court admitted the independent evidence because the immunity order satisfied the constitutional requirements.
Kastigar v. United States406 U.S. 441 (1972)
Derivative Statement Suppression
Simon Stern made an unwarned statement during an illegal arrest. Agents later obtained a second statement after proper warnings. The court suppressed the second statement because it was the fruit of the initial violation. The self-incrimination claim succeeded on the derivative-evidence theory.
Wong Sun v. United States371 U.S. 471 (1963)
Custodial Interrogation Without Warnings
Sierra Santos was taken into custody and questioned for several hours about a suspected fraud scheme. Officers never advised her of her right to remain silent. The court excluded her resulting confession because the interrogation occurred without the required warnings. The self-incrimination claim barred use of the statement at trial.

Common questions
Frequently Asked
5
Does the privilege apply to a witness in someone else's criminal trial?+
Yes. The privilege protects any person compelled to give testimonial evidence that might tend to incriminate the person in a future criminal prosecution. It applies whether the person is a defendant or merely a witness and whether the proceeding is federal or state.

Does forcing a person to enter a computer passphrase violate the privilege?+
Yes when the act communicates the person's knowledge and control of the device. The communication is testimonial because it reveals the contents of the mind. Courts therefore sustain objections to such demands absent adequate immunity.
Must a witness appear before a grand jury even if some questions may be incriminating?+
Yes. A valid subpoena requires appearance and the taking of an oath. The witness may then assert the privilege on a question-by-question basis when a truthful answer would tend to incriminate the witness.
Supporting sources
Does the privilege protect a corporation or its custodian from producing records?+
No. The privilege is personal to natural individuals and does not extend to artificial entities or to custodians acting in a representative capacity.
Supporting sources
Is a blood-alcohol test refusal considered testimonial evidence?+
No. Refusal to submit to a blood-alcohol test is nontestimonial conduct. Admission of the refusal therefore does not violate the privilege even without prior warnings.
