Hornbooks
Samantha told officers in the alley that Gerald had left to retrieve a gun. The court determined that the primary purpose of the questioning made the statements testimonial or communicative in nature, triggering the need for prior cross-examination.
Forfeiture-by-Wrongdoing Claim
After the defendant caused a witness's unavailability, the prosecution offered the witness's prior statement. The court required proof that the defendant acted with intent to prevent testimony before treating the statement as admissible despite its testimonial or communicative character.
Lab Report Without Analyst
The prosecution introduced a forensic report identifying bacteria on a knife through a surrogate witness. The court held that the report constituted testimonial or communicative evidence because it contained the analyst's out-of-court conclusions, requiring live testimony from the actual analyst.
Child's Statements to Teachers
A child abuse victim told teachers the identity of the abuser. The court concluded that the statements were not testimonial or communicative in nature because their primary purpose was to address an ongoing emergency and protect the child rather than to create evidence for prosecution.
Common questions
Frequently Asked
4
What distinguishes testimonial or communicative evidence from physical evidence under the Fifth Amendment?+
Testimonial or communicative evidence reveals the contents of the mind of the person compelled to produce it. Physical evidence such as handwriting or voice exemplars does not trigger the privilege because it does not require the individual to communicate thoughts or knowledge.
Does the marital communications privilege protect only statements that are testimonial or communicative in nature?+
Yes. The privilege protects confidential communications between spouses because those communications require one spouse to disclose the contents of the mind. The government bears the burden of overcoming the presumption that such communications were confidential.
When does an out-of-court statement become testimonial or communicative in nature for Confrontation Clause purposes?+
A statement is testimonial or communicative in nature when its primary purpose is to establish or prove past events potentially relevant to criminal prosecution. Statements made during an ongoing emergency to enable police assistance are not testimonial.
Are forensic laboratory reports testimonial or communicative in nature?+
Yes. Forensic laboratory reports prepared for use in criminal prosecution contain the analyst's conclusions and therefore constitute testimonial or communicative statements. Admission without testimony from the analyst who prepared the report violates the Confrontation Clause.
