South Carolina Code of Regulations
Chapter 103 - PUBLIC SERVICE COMMISSION
Article 8 - PRACTICE AND PROCEDURE
Section 103-845 - Witnesses

A. In General. Witnesses shall be examined orally. Witnesses presenting testimony shall be sworn, or shall affirm, before their testimony shall be deemed evidence in the proceeding or any questions are put to them.

B. Cumulative Testimony Restricted. The presiding officer may limit the number of witnesses whose testimony may be merely cumulative. In order to enforce this section, the presiding officer may require a clear statement on the record of the nature of the testimony to be given by any witness proffered.

C. Prepared Statements and Exhibits. A witness may read into the record, as his direct testimony, statements of fact or expressions of his opinion prepared by him, or written answers to interrogatories of counsel. A prepared statement of a witness may also be received as an exhibit. All parties of record, insofar as it is practicable, should prefile with all other parties of record copies of prepared testimony and exhibits which the party of record proposes to use during a hearing. In proceedings involving utilities, the Commission shall require any party and the Office of Regulatory Staff to file copies of testimony and exhibits and serve them on all other parties of record within a specified time in advance of the hearing. In proceedings involving companies other than utilities, the Commission may require any party and staff to file copies of testimony and exhibits and serve them on all other parties of record within a specified time in advance of the hearing. When prepared testimony and exhibits are prefiled with the Commission, twenty-five copies, unless otherwise specified, of such testimony and exhibits must be furnished to the Commission for the use of the Commission and Staff.
