S.C. Code Ann. § 56-5-2934
Notwithstanding any other provision of law, a person charged with a violation of Section 56-5-2930, 56-5-2933, or 56-5-2945 who is being tried in any court of competent jurisdiction in this State has the right to compulsory process for obtaining witnesses, documents, or both, including, but not limited to, state employees charged with the maintenance of breath testing devices in this State and the administration of breath testing pursuant to this article. This process may be issued under the official signature of the magistrate, judge, clerk, or other officer of the court of competent jurisdiction. The term "documents" includes, but is not limited to, a copy of the computer software program of breath testing devices. The portion of compulsory process provided for in this section that requires the attendance, at any administrative hearing or court proceeding, of state employees charged with the maintenance of breath testing devices in this State and the administration of breath testing pursuant to this article, takes effect once the compulsory process program at the State Law Enforcement Division is specifically, fully, and adequately funded.
In addition, at the time of arrest for a violation of Section 56-5-2930, 56-5-2933, or 56-5-2945, the arresting officer, in addition to other notice requirements, must inform the defendant of his right to all hearings provided by law to include those if a breath test is refused or taken with a result that would require license suspension. The arresting officer, if the defendant wishes to avail himself of any such hearings, depending on the choices made or the breath test results obtained, must provide the defendant with the appropriate form to request the hearing or hearings. The defendant must acknowledge receipt of the notice requirements and receipt of the hearing form if such a hearing or hearings are desired.
