Employees may not act, or give the appearance of acting, on behalf of the Laboratory or the University when communicating with State or Federal officials unless they are authorized to do so.

When corresponding with State and Federal officials, Laboratory letterhead may be used only when the writer is authorized to represent the Laboratory or the University. Letters expressing personal views must be written on personal stationery. If Laboratory letterhead is used for corresponding with principal State and Federal officials, including Executive Branch appointees, members of Congress, the State Legislature, and their staff, copies of the correspondence must be sent to the appropriate Division Head and to the Associate Laboratory Director for Planning and Development.

When employees give opinions as independent professionals, they must state clearly that they are speaking for themselves and not on behalf of the Laboratory or the University of California.
