S.C. Code § 12-60-520
A taxpayer who requests a contested case hearing may elect to designate the action as a small claims case if no more than ten thousand dollars of taxes, including penalties, but not including interest, are in controversy at the time of filing the request for a contested case hearing. The designation must be made at the time the request for a contested case hearing is made and be included in the request. The decision of the administrative law judge in an action designated as a small claims case is final and conclusive and may not be reviewed by a court. A case decided pursuant to this section may not be cited by either the department or a taxpayer in a future action and establishes no precedent except for the taxpayer involved and the tax period or periods in controversy. This section does not apply to actions that raise constitutional issues.
