(a) City councils in cities of the second class shall have the authority to redistrict the wards of their cities when they determine that the people can best be served by adding wards, combining wards, or changing ward boundary lines to equalize the populations in the various wards.
(b)
(1) Within ninety (90) days after redistricting, if fifty (50) or more qualified electors in the city are dissatisfied with the division of the city into wards, they shall have the authority to petition the circuit court.
