Conducting Interviews and Depositions

In addition to these sources, expert witnesses may also gather information by conducting interviews and depositions of the parties involved in the case, including witnesses, plaintiffs, defendants, or any other party with first-hand information about the case. First-hand knowledge can provide more views and information that may not be available from documents.

Ethical Considerations for Lawyers Who Engage Experts

When lawyers engage expert witnesses for testimony, they ought to maintain fairness and transparency throughout the process. These practices not only maintain credibility but also safeguard the fairness of the legal proceedings. Expert witness ethics are crucial in providing litigation support.

Maintaining Fairness to Opposing Counsel and Parties (Rule 3.4):

Rule 3.4 prevents lawyers from frustrating the course of justice through denying access to evidence, tampering with or altering evidence, or encouraging others to do so. Lawyers should not make frivolous discovery requests, fail to comply with obligations imposed by the tribunal in the conduct of the litigation, or present irrelevant or unsupported material in trial. It also prohibits them from offering personal opinions as to a case or inducing others to withhold relevant information, except where it does not injure their interest.

Ensuring Expert Objectivity and Impartiality

It is one of the core ethical duties of lawyers when engaging an expert witness to ensure objectivity and impartiality on the part of the expert. Expert witnesses must base their testimony solely on the facts, data, and scientific analysis relevant to the case—not on the lawyer’s desired outcome.

Transparency and Disclosure of Expert Witness Roles

Lawyers must clearly state out the extent of involvement of expert witnesses in the case. By doing this they would minimise any potential for conflict of interest.

Disclosure of Compensation and Conflicts

Ethically, lawyers are compelled to disclose any compensation that they would bear to an expert witness. This ensures that the witness remains impartial and no financial motives are attached to testifying. 

Disclosure of Adverse Authority

If the lawyer becomes aware of adverse authority or contrary opinions that may impact the expert’s opinion, they have an ethical duty to disclose such information to the expert and to opposing counsel.

Ensuring Prompt Payment of Expert Witness Fees

It is imperative to provide the expert witness fees in a timely manner. Delayed or unfair remuneration may damage the relationship between the lawyer and the witness. This may impact the willingness of the expert to continue offering services or testify in future cases. 

Protecting Attorney-Client Privilege and Confidentiality

It is the lawyer’s job to ensure that any financial expert witness they hire  is well versed in protecting the confidences of any sensitive information associated with the matter.
