S.C. Code Ann. § 42-17-50: Review and rehearing by commission.

If an application for review is made to the commission within fourteen days from the date when notice of the award shall have been given, the commission shall review the award and, if good grounds be shown therefor, reconsider the evidence, receive further evidence, rehear the parties or their representatives and, if proper, amend the award.

Each application for commission review must be accompanied by a fee equal to that charged in circuit court for filing a summons and complaint in order to defray the costs of the review. If the commission determines at the conclusion of the review that the appeal was without merit, it may charge, in its sole discretion, the appellant an additional fee not to exceed two hundred fifty dollars.
