TheSouth Carolina State Senate is the upper house of theSouth Carolina General Assembly, the state legislature of the U.S. state ofSouth Carolina. The lower house is theSouth Carolina House of Representatives. The Senate comprises 46 senators elected from single-member districts for four-year terms, coinciding withUnited States presidential elections.
TheSouth Carolina Constitution of 1895 initially stipulated that eachcounty would elect one senator for a four-year term, with elections staggered biennially. Following the 1964U.S. Supreme Court ruling inReynolds v. Sims, the Senate underwent reapportionment. A temporary measure in 1966 established 27 districts with 50 members serving two-year terms. In 1967, the Senate was again reapportioned into 20 districts with 46 members, serving four-year terms. The number of districts was reduced to 16 in 1972, and by 1984, the state adopted a system of single-member districts.
The General Assembly convenes annually at theState Capitol Building inColumbia on the second Tuesday of January. Either the House or the Senate may, by a majority vote, declare a 30-day recess, or a longer recess with a two-thirds vote.[1]
