For section 521 proceedings, this section shall apply in lieu of § 18.14 of this title:

(a) A party may file a motion to conduct discovery with the administrative law judge. The administrative law judge may grant a motion for discovery only upon a showing of good cause. In order to establish “good cause” for the purposes of this section, the moving party must show that the requested discovery relates to a genuine issue as to a fact that is material to the section 521 proceeding. The order of the administrative law judge shall expressly limit the scope and terms of the discovery to that for which “good cause” has been shown, as provided in this paragraph.

(b) Any evidentiary privileges apply as they would apply in a civil proceeding in federal district court. For example, legal advice provided by an attorney to a client is generally protected from disclosure. Mental impressions, conclusions, opinions, or legal theories of a party's attorney or other representative developed in anticipation of litigation are also generally protected from disclosure. The administrative law judge may not, however, protect from discovery or use, relevant communications between an attorney and a plan administrator or other plan fiduciary, or work product, that fall under the fiduciary exception to the attorney-client or work product privileges. The fiduciary exception to these privileges exists when an attorney advises the plan administrator or other plan fiduciary on matters concerning plan administration or other fiduciary activities. Consequently, the administrative law judge may not protect such communications from discovery or from use by the Secretary in the proceedings. The administrative law judge also may also not protect attorney work product prepared to assist the fiduciary in its fiduciary capacity from discovery or from use by the Secretary in the proceedings. The fiduciary exception does not apply, however, to the extent that communications were made or documents were prepared exclusively to aid the fiduciary personally or for non-fiduciary matters (e.g. settlor acts), provided that the plan did not pay for the legal services. The Secretary need not make a special showing, such as good cause, merely to obtain information or documents covered by the fiduciary exception. Other relevant exceptions to the attorney-client or work product privileges shall also apply.
