A. In any case where an employer changes insurance carriers or where the employer having been self-insured, becomes insured or, having been insured, is approved to be self-insured, and the only dispute in a claim against that employer is the proper source of payment of benefits, the Commission shall direct that the appropriate compensation benefits be paid on an equal basis by the carriers or self-insured employer.

B. Upon resolution of the issue, the prevailing respondent shall be entitled to reimbursement from the other respondent of all monies paid together with interest from the date of payment pursuant to Section 727.1 of Title 12 of the Oklahoma Statutes.
