S.C. Const. art. I, § 17
Treason against the State shall consist alone in levying war or in giving aid and comfort to enemies against the State. No person shall be held guilty of treason, except upon testimony of at least two witnesses to the same overt act, or upon confession in open court.
(1970 (56) 2684; 1971 (57) 315; 2007 Act No. 15.)
The present provisions of the first paragraph of this section are identical to former Section 22 of Article I as it existed prior to the 1971 revision. It would seem that the intention of the 1973 amendments relating to slum clearance (1970 (57) 1340; 1973 (58) 123) was to add the provisos of the second and third paragraphs of this section to Section 17 of this article as it existed prior to the 1971 revision. Similar paragraphs were transferred to Section 5 of Article XIV by the 1971 amendment which revised this article.
