For the purpose of revising and correcting assessments, the Board of Review shall have the same powers and perform like duties, in all respects, as are, by law, conferred upon and required of boards of review in townships, except as otherwise provided in this Charter. At the time, and in the manner provided in the following section, it shall hear the complaints of all persons considering themselves aggrieved by assessments. If it shall appear that any person or property has been wrongfully assessed or omitted from the roll, the Board shall correct the roll in such manner as it deems just. Except as otherwise provided by law, no person other than the Board of Review shall make any change upon, or addition or correction to, the assessment roll. The Assessor shall make a permanent record of all proceedings of the Board and enter therein all resolutions and decisions of the Board. Such record shall be filed with the Clerk on or before the first day of May following the meeting of the Board of Review.
