Arizona Revised Statutes Title 41. State Government § 41-1962. Conflict with federal law

Where any conflict with federal law occurs concerning the programs and functions of the department as established by the law of this state, such federal law shall control. For purposes of this section, “federal law” means any statute passed by the Congress of the United States, any final regulations adopted by any administrative agency of the United States government and published in the Code of Federal Regulations or the federal register or any final decision of the federal judiciary. A conflict between federal law and the law of this state does not exist for purposes of this section unless the source of the federal law, on its face or so clearly as not to require any additional interpretation, establishes the conflict. Upon notification of a conflict with federal law where the conflict does not meet the requirements of this section, the department may conform its programs and functions to eliminate the alleged conflict on condition that the department contest the alleged conflict.
