The Laboratory is bound by a variety of conflict-of-interest policies, some of which emanate from the U.S. Department of Energy (DOE) contractual requirements (DOE Contract No. DE-AC02-05CH11231, also known as Contract 31) and some of which are founded on University policies, California law, and federal regulations. These policies pertain to a broad range of employee activities, including compensated outside business and professional activities, hiring procedures, sponsored research, human subjects research, licensing, and technology transfer. An employee who fails to comply with Laboratory conflict-of-interest policies may incur disciplinary action by the Laboratory and prosecution under state law. These policies apply to all Laboratory employees regardless of percent time of appointment at the Laboratory, including rehired retirees and University of California faculty associated with the Laboratory.
