On 9 February 2010, the Senate decided that presidential power should be given to the Vice President. He was appointed to serve as Acting President, with all the accompanying powers, until when and if Yar'Adua returned to full health. The power transfer was called a "coup without the word" by opposition lawyers and lawmakers. The Nigerian Constitution requires a written letter from the President stating he is unable to serve or that the cabinet sends a medical team to examine him but this provision has not apparently been fulfilled leaving some doubts as to the constitutionality of the action.
