The Tax Court shall have full power to hear, try, determine, or remand any matter before it. In exercising these powers, the Tax Court may reassess or reclassify, abate, modify, change or alter any valuation, assessment, classification, tax or final order appealed to the Tax Court. Absent affirmative evidence in support of the relief being sought or an error apparent on the face of the proceeding from which the appeal is taken, the decision, determination, or order from which the appeal is taken shall be affirmed.
