(1)    Designation and use of a temporary location by the governor. Whenever, as the result of a disaster or the imminent threat of a disaster, it becomes imprudent, inexpedient or impossible to conduct the affairs of state government at the state capital, the governor shall, as often as the exigencies of the situation require, designate a temporary location for the seat of government at a place in or outside this state. The governor shall take any action and issue any orders necessary for an orderly transition of the affairs of state government to the temporary location. If practicable, the temporary location the governor designates shall conform to that provided for in the current emergency management plan authorized under subch. II. The temporary location shall remain as the seat of government until the governor establishes a new location under this section, or until the seat of government is returned to its normal location.

   (1m)   Designation of temporary location by the legislature.

      (a)    The legislature, by joint rule, may provide a process for designating a temporary seat of government for the legislature that is different than the location under sub. (1).

      (b)    Whenever, as the result of a disaster, as defined in s. 13.42 (1) (a), or the imminent threat of a disaster, it becomes imprudent, inexpedient, or impossible to conduct the business of the legislature at the state capital, the legislature may meet at the temporary location designated as provided under par. (a) or sub. (1) until it is no longer, as a result of the disaster or imminent threat of disaster, imprudent, inexpedient, or impossible, to conduct the business of the legislature at the state capital.

      (c)    Pursuant to the session schedule under s. 13.02 (3), the legislature may meet for up to one week per session in a location that is not the state capital or the temporary location designated as provided under par. (a) or sub. (1) to practice meeting at a temporary location.

      (d)    Information about the temporary location designated as provided under par. (a) is not subject to inspection or copying under s. 19.35 (1).

   (2)   Exercise of governmental authority. While the seat of government remains at a temporary location all official acts required by law to be performed at the seat of government by any officer, independent agency, department, or authority of this state, including the convening and meeting of the legislature in regular or special session under sub. (1) or (1m) (b) or (c), shall be as valid and binding when performed at the temporary location as if performed at the normal location.
