of his Cabinet, with Aquino himself as Secretary of the Interior and Local Government.

Inauguration The inauguration of President-elect Benigno Aquino III and Vice-President elect Jejomar Binay was held at the Quirino Grandstand in Luneta Park, Manila on June 30, 2010. The oath of office was administered by Associate Justice of the Supreme Court of the Philippines Conchita Carpio-Morales, who officially accepted Aquino's request to swear him into office, reminiscent of the decision of his late mother, who in 1986, was sworn into the presidency by Associate Justice Claudio Teehankee. Aquino refused to allow Chief Justice of the Supreme Court of the Philippines Renato Corona to swear him into office, due to Aquino's opposition to the midnight appointment of Corona by outgoing President Gloria Macapagal Arroyo.
