Whenever the Assessor, in the performance of the Assessor's
duties, requests or obtains income and expense information pursuant
to § 70.47(7)(af), Wis. Stats., or any successor statute
thereto, then such income and expense information that is provided
to the Assessor shall be held by the Assessor on a confidential basis;
except, however, that said information may be revealed to and used
by persons: in the discharging of duties imposed by law; in the discharge
of duties imposed by office (including but not limited to use by the
Assessor in performance of official duties of the Assessor's office
and use by the Board of Review in performance of its official duties);
or pursuant to order of a court. Information shall not be redisclosed
by any such individuals to any person or persons not authorized to
receive that information. Income and expense information provided
to the Assessor under this section, unless a court determines that
it is inaccurate, shall not be subject to the right of inspection
and copying under § 19.35(1), Wis. Stats.
