Okla. Stat. tit. 85A, § 85A-108: Dismissal of claims

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.
