Tax foreclosure proceedings; defects subsequent to decree of foreclosure; hearing; determination

Upon hearing the application, the court shall enter a supplemental decree directing that the tax foreclosure proceeding be properly completed, and determining the rights of all parties that have arisen subsequent to the entry of the decree of foreclosure. The rights adjudicated in the original tax foreclosure proceeding shall be respected and observed, but such adjudication shall not prevent any party from establishing superior rights that may have arisen since the entry of the decree through payment of subsequent taxes and special assessments and the placing of improvements on the premises in good faith. In the event any municipal corporation or governmental subdivision shall have received any consideration as the result of the proceedings which were defective, invalid, or void, it shall be required to account for the same, and judgment may be entered against it for the amount thereof and applied as a credit on any amount due it under the original decree of foreclosure.
