The Navajo Nation Code defines who may become or act as president upon the absence of a sitting president or a president-elect. Should the president, under circumstances outlined in the Navajo Nation Code at §1005(d)-1006, be unable to serve out his full term, then the vice president shall act in his place for the remainder of the term, or until the president is able to resume his duties. §1006 of the Code instructs, that in the event a vacancy should "occur in the Office of President and Vice President, the Speaker shall serve as President of the Navajo Nation until a special election is held." The speaker does not relinquish his speaker duties whilst acting as interim president.
