A civil investigative demand issued under this article shall not require the production of any documentary material, the submission of any answers to written interrogatories, or the giving of any oral testimony if such material, answers, or testimony would be protected from disclosure under (i) the standards applicable to subpoenas or subpoenas duces tecum issued by a court of this Commonwealth to aid in a grand jury investigation or (ii) the standards applicable to discovery requests under the Rules of the Supreme Court of Virginia, to the extent that the application of such standards to any such demand is appropriate and consistent with the provisions and purposes of this article. Any such demand that is an express demand for any product of discovery supersedes any inconsistent order, rule, or provision of law, other than this section, preventing or restraining disclosure of such product of discovery to any person. Disclosure of any product of discovery pursuant to any such express demand does not constitute a waiver of any right or privilege that the person making such disclosure may be entitled to invoke to resist discovery of trial preparation materials.
