Any person aggrieved by a decision or order of the commission may, within seven (7) days from the date of the decision or order, petition the supreme court for a writ of certiorari to review the legality and reasonableness of the decision or order. The petition for a writ of certiorari shall fully set forth the specific reasons for which it is claimed that the decision or order is unlawful or unreasonable. Chapter 35 of title 42 shall not be applicable to appeals from the commission.
