The proper citation to a South Carolina regulation includes the volume number where the regulation is published in the South Carolina Code of Regulations, that regulation's chapter and section, and the year of the volume or supplement where the regulation appears.
For example, the South Carolina Lottery Commission regulation for claiming prizes referenced above would be cited as follows:
This citation indicates that currently the entire regulation (44-70) is published in the 2011 hardbound regulations volume that contains Chapter 44. The information in the parenthesis would be different if the statute appeared in the supplement only [3 S.C. Code Ann. Regs. 44-70 (Supp. 2014)] or if portions of the regulation appeared in both the hardbound volume and the supplement [3 S.C. Code Ann. Regs. 44-70 (2011 & Supp. 2014)].
Rule 268 also recommends The Bluebook: A Uniform System of Citation published by the Harvard Law Review Association and A Guide to South Carolina Legal Research and Citation by Paula Gail Benson (S.C. Bar C.L.E. Division) for additional guidance.
