On March 23, the Federal Reserve and the Office of the Comptroller of the Currency – both non-parties in the suit – filed briefs requesting that a district court reject a motion to compel discovery of over 30,000 documents held by a large bank.  Arguing that the documents contain confidential supervisory information, the regulators asserted the bank examination privilege – “a qualified privilege that protects communications between banks and their examiners in order to preserve absolute candor essential to the effective supervision of banks.”  As for scope, the regulators argued that the privilege covers the documents because they provide agency opinion, not merely fact, and that any factual information was nonetheless “inextricably linked” with their opinions.  Additionally, they contended that the privilege is not strictly limited to communications from the regulator to the bank – instead, it may also cover communications made from the bank to the regulator and communications within the bank.  As for procedure, the regulators claimed that a plaintiff is required to request the disclosure of privileged documents through administrative processes before seeking judicial relief, a requirement they contend exists even where a defendant bank also holds copies of the documents. Finally, the regulators argued in the alternative that the lead plaintiff has not shown good cause to override the qualified privilege, as the interests of the government in protecting the supervisory information outweighs the interest of the plaintiffs in production.
