The bill H. 3999 proposes amendments to the South Carolina Constitution regarding dual office holding. Specifically, it seeks to exempt any office holder or appointee whose position is wholly uncompensated, except for per diem and expense reimbursement as provided by law, from the prohibitions against holding two offices of honor or profit simultaneously. This change is reflected in the proposed amendments to Section 3 of Article VI and Section 1A of Article XVII, which clarify that the dual office holding limitations do not apply to individuals in these specific circumstances.

To implement these amendments, the bill mandates that the proposed changes be presented to qualified electors during the next general election. Voters will be asked to approve or disapprove the amendments through a ballot that includes the question of whether to exempt uncompensated office holders from dual office holding restrictions. The bill aims to facilitate the participation of individuals in public service roles without the concern of violating dual office holding laws, provided they are not receiving compensation beyond specified reimbursements.
