The First Presidency's office completes documents which give Counselors Gordon B. Hinckley and Thomas S. Monson power of attorney for church president Ezra Taft Benson, which "shall not be affected by [his] disability" or "incompetance." The church president does not sign these legal documents which are instead "signed" by a signature machine in the First Presidency's office. The identical signature of Ezra Taft Benson also appears on a similar document, dated 25 Feb. 1993, and also filed with the state of Utah. Although the Presidency's office uses its AUTO-PEN machine to create the church president's signature on correspondence, missionary calls, and other routine documents, this use of signature machine for legal documents (especially power-of-attorney) is unprecedented. Disclosure of this by the Salt Lake Tribune fuels speculation that Benson is already in mental decline by 1989.
