Section 1. Grounds of and period for filing motion for new trial or reconsideration. - Within the period for taking an appeal, the aggrieved party may move the trial court to set aside the judgment or final order and grant a new trial for one or more of the following causes materially affecting the substantial rights of said party:
(a) Fraud, accident, mistake or excusable negligence which ordinary prudence could not have guarded against and by reason of which such aggrieved party has probably been impaired in his rights; or
(b) Newly discovered evidence, which he could not, with reasonable diligence, have discovered and produced at the trial, and which if presented would probably alter the result.
Within the same period, the aggrieved party may also move for reconsideration upon the grounds that the damages awarded are excessive, that the evidence is insufficient to justify the decision or final order, or that the decision or final order is contrary to law. (1a)
