Evidence

It is a basic tenet in U.S. JURISPRUDENCE that "the public … has a right to every [person's] evidence," and that parties in litigation should avail themselves of all rational means of ascer taining truth (Trammel v. United States, 445 U.S. 40, 100 S. Ct. 906, 63 L. Ed. 2d 186 [1980]). Yet courts view certain interests and relationships to be of such importance that they protect those interests and relationships from certain efforts to gather evidence. These protections, or exclusions from the general rule of free access to evidence, are known as privileges.

Federal courts recognize several types of privileges. To encourage clients to communicate freely with their lawyers and to fully disclose any information that may enable their lawyers to provide appropriate legal advice, courts allow clients to refuse to disclose and to prevent any other person from disclosing confidential communications made when seeking legal services. This privilege applies to clients' communications with their attorneys and with the attorneys' office staff. It protects only confidential communications, not communications made to friends or acquaintances in addition to an attorney.

The ATTORNEY-CLIENT PRIVILEGE applies to the client, not the attorney. Thus, the client, but not the attorney, has the right to waive the privilege and to testify regarding protected communications. The privilege does not terminate even when the attorney-client relationship does. The privilege does not apply to a client's allegations of a breach of duty by the attorney.

To promote open communication within marital relationships, the rules of evidence also recognize a marital privilege. In criminal cases, a person has the privilege to refuse to testify against a spouse. This privilege covers only evidentiary matters that would incriminate the non-testifying spouse (i.e., the defendant), as other matters are not likely to jeopardize the marriage relationship. The non-testifying spouse does not have the right to assert the privilege; the privilege belongs only to the testifying spouse.

In criminal and civil cases, testimony about any confidential communications between spouses is also afforded a privilege. Either spouse, not just the testifying spouse, may assert this privilege. Unlike the testifying-spouse privilege, the confidential-marital-communications privilege survives the termination of the marriage by death or DIVORCE, but it does not apply to permanently separated spouses.

Courts also recognize a political-vote privilege, a clergy-penitent privilege, and qualified privileges for trade secrets, state secrets, and the identity of an informant. Some courts also recognize a physician-patient privilege, an accountant-client privilege, and a privilege granted to journalists seeking to protect their news sources.
