Agreement Between the President and the Vice President as to Procedures in the Event of Presidential Disability.
THE PRESIDENT and the Vice President have agreed that the following procedures are in accord with the purposes and provisions of Article 2, Section I, of the Constitution, dealing with Presidential inability. They believe that these procedures, which are intended to apply to themselves only, are in no sense outside or contrary to the Constitution but are consistent with its present provisions and implement its clear intent.
(1) In the event of inability the President would--if possible--so inform the Vice President, and the Vice President would serve as Acting President, exercising the powers and duties of the Office until the inability had ended.
(2) In the event of an inability which would prevent the President from so communicating with the Vice President, the Vice President, after such consultation as seems to him appropriate under the circumstances, would decide upon the devolution of the powers and duties of the Office and would serve as Acting President until the inability had ended.
(3) The President, in either event, would determine when the inability had ended and at that time would resume the full exercise of the powers and duties of the Office.
Note: This is the text of agreement as set forth in a White House news release of this date.
