(a) In all cases the assessor shall consider the petition and shall rule on each petition filed pursuant to 11-3-15c, 11-3-15d, or 11-3-15e of this code by February 10 of the assessment year. Written notice shall be served by regular mail on the person who filed the petition.

(c) The consideration of a petition for review with the assessor is to be an informal process. Formal rules of evidence shall not be required; the assessor may consider all evidence presented and may give each item the weight, in his or her opinion, it commands.
(d) The standard of proof which a taxpayer must meet to defend his or her opinion of the true and actual value of the subject property during reviews by the assessor shall be no greater than a simple preponderance of the evidence standard.
