The board of review or board of appeals of the county in which a reassessment is made shall review, correct, and equalize the reassessment in the same manner and subject to the same laws and rules as an original assessment. The Department shall fix the time and place of the meeting of the board to review and correct the reassessment. At least one week before the meeting, the board shall publish a notice of the time and place of its meeting, in at least one newspaper of general circulation published in the county in which the reassessment is made, except that in every township in which there is published one or more newspapers of general circulation the notice shall be published in one of those newspapers in each township. The board shall convene at the time and place fixed in the order, and shall review, correct, return and certify the reassessment in like manner, and shall have and exercise all the powers and authority given to boards of review or boards of appeals, and shall be subject to all the restrictions, duties and penalties of those boards. When a reassessment has been ordered, the board, at the time and place fixed in the notice given as required by this Section, may hear complaints and review and correct the reassessment by townships or assessment districts, as the reassessment for such townships or assessment districts is completed and certified by the chief county assessment officer, without waiting for the completion of the entire reassessment. Two or more townships or assessment districts may be notified for a revision and correction at the same time.
