Sec. 12.9.  ORGANIZATION AND FUNCTIONS OF THE BOARD OF REVIEW.
   On the first day of its meeting in each year, the Board of Review shall elect one of its members chairman. The Assessor shall be Secretary of the Board and shall attend its meetings with the privilege of participating therein but without the right to vote upon any decision of the Board. It shall be the duty of the Assessor to keep a permanent record of all proceedings, and to enter therein all resolutions and decisions of the Board. A majority of the members of the Board shall constitute a quorum. The members of said Board shall take the constitutional oath of office which shall be filed with the Clerk. For the purpose of reviewing and correcting assessments, the Board of Review shall have the same powers and perform like duties in all respects as are by the general law conferred upon and required of boards of review in townships, in reviewing assessments in townships for township, state, and county taxes. It shall hear the complaints of all persons considering themselves aggrieved by assessments, and 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 shall deem just. In all cases, the assessment roll shall be reviewed according to the facts existing on the tax day and no change of the status of any property after said day shall be considered by the Board in making its decisions.
   After the Board of Review has completed its review of the assessment roll, and not later than the first Monday in April, the majority of its members shall endorse thereon and sign a statement to the effect that the same is the assessment roll of the city for the year in which it has been prepared. The omission of such endorsement shall not affect the validity of such roll.
