Within thirty days from the date of notification or mailing, whichever is the earlier, of any decision of an administrative law judge, the commissioner on the commissioner's own order may, or upon petition of any interested party shall, take jurisdiction of the proceedings for the purpose of review. Appeal from any decision of an administrative law judge may be perfected so as to prevent finality of such decision if, within thirty days from the date of notification or mailing of the decision, whichever is the earlier, a petition in writing for review by the commissioner is received by the commissioner or by such representative of the commissioner as the commissioner by rule shall prescribe. The commissioner may also prevent finality of any decision of an administrative law judge and take jurisdiction of the proceedings for his or her review by entering an order so providing on his or her own motion and mailing a copy thereof to the interested parties within the same period allowed for receipt of a petition for review. The time limit provided for the commissioner's assumption of jurisdiction on his or her own motion for review shall be deemed to be jurisdictional.
