As non-testifying experts, the federal rules do not require consulting experts to provide disclosures to the other parties. By contrast, testifying experts are required to provide disclosures to the opposing party, including an expert report, and their work and opinions are afforded less protection against discovery.
The attorney-client privilege applies to communications “to whom disclosure is reasonably necessary for the transmission of the information or the accomplishment of the purpose for which the lawyer is consulted.” Cal. Evid. Code § 952. This includes communications to an expert consultant.
Depending on the jurisdiction, a consulting expert's identity may not be discoverable. In other words, the work of a consulting expert need not be disclosed to the opposing party, whereas the testifying expert's opinions, notes, and work product are all discoverable.
The attorney-client privilege does not apply to every communication with an attorney. For the privilege to exist, the communication must be to, from, or with an attorney, and intended to be confidential. In addition, the communication must be for the purpose of requesting or receiving legal advice.
Consulting experts work behind the scenes to analyze complex issues and identify weaknesses. Their confidential advice helps shape arguments. Expert witnesses, in contrast, present these findings in court, offering scientifically sound testimony that can sway the judge or jury.
The difference between consultants and expert witnesses is that a consultant is not a witness in your case, while an expert witness will testify in court hearings. It's a critical difference, because if an expert is strictly a consultant, all communication and information exchanged with the consultant is privileged.
The elements required to establish the attorney-client privilege are as follows: a communication; made between privileged persons; in confidence; and. for the purpose of seeking, obtaining, or providing legal assistance to the client.
A consulting expert is someone who has a lot of knowledge or experience in a certain subject and can help people understand it better. They are usually hired by one side in a legal case to give advice, but they are not expected to testify in court.
There are two major exceptions to the lawyer-client privilege under the California Evidence Code, as discussed below. 2.1. Crime or fraud. 2.2. Preventing death or substantial physical harm.
