(1) All the Federal President's responsibilities, should he be prevented from their discharge, pass in the first instance to the Federal Chancellor. A sojourn in another member state of the European Union is not deemed to be an impediment. If the impediment lasts longer than twenty days or if pursuant to Art. 60 para 6 the Federal President is prevented from the discharge of his office, the President, the Second President, and the Third President of the National Council acting as a committee shall undertake the responsibilities of the Federal President. The same holds good if the position of the Federal President is continuously in abeyance.
