Sub. (3) is amended, effective the day after the secretary of state notifies the legislature that an amendment to the Wisconsin Constitution has been approved that requires the legislature to provide for temporary succession to the powers and duties of public offices for the period of an emergency resulting from a cause other than an enemy action, to read as follows:
(3) Period during which authority may be exercised. An interim successor to an office may discharge the duties of the office only during the continuance of an emergency resulting from a disaster or the imminent threat of a disaster.
