Any claimant may, upon the payment of the Workers' Compensation Commission's filing fee, dismiss any claim brought by the claimant at any time before final submission of the case to the Commission for decision. Such dismissal shall be without prejudice unless the words "with prejudice" are included in the order. If any claim that is filed within the statutory time permitted by Section 18 of this act is dismissed without prejudice, a new claim may be filed within one (1) year after the entry of the order dismissing the first claim even if the statutory time for filing has expired.
