On June 3, 2010, Alioto-Pier submitted papers to register as a candidate for re-election to District Two of the San Francisco Board of Supervisors. San Francisco Department of Elections Director John Arntz issued a letter that same day in which he announced she was ineligible to run for re-election for District Two supervisor due to a 2008 ruling regarding term limits issued by City Attorney Dennis Herrera. Arntz wrote, "Accordingly, the Department of Elections cannot list you as a candidate for this office on the November 2, 2010 ballot or any other election materials for that election." She would have served on the Board of Supervisors for seven years when her term expired in January 2011. Supervisors are limited to serving two four-year terms.
