The Secretary amends the regulations regarding the production of information pursuant to demands in judicial or administrative proceedings. The changes are intended to promote consistency in the Department's assertion of privileges and objections, and thereby prevent harm that may result from inappropriate disclosure of confidential information or inappropriate allocation of agency resources. These changes apply only where employees are subpoenaed in litigation to which the agency is not a party. Former Department employees are expressly required to seek the Secretary's approval prior to responding to subpoenas that seek non-public materials and information acquired during their employment at the Department.
