(3)  a taxing unit other than a county that has territory in a county described by Subdivision (1) or (2).
(c)  If, as a result of disputed, overlapping, or erroneously applied geographic boundaries between like taxing units, multiple like taxing units have imposed ad valorem taxes on the same property, the property owner may file suit in the supreme court to:
(1)  establish the correct geographic boundary between the taxing units; and
(2)  determine the amount of taxes owed on the property and the taxing unit or units to which the taxes are owed.
