Sales of alcoholic liquor on Election Day allowed, Christmas Day prohibited

SECTION    6.    A.        Section 61-6-4160 of the 1976 Code is amended to read:

“Section 61-6-4160.    It is unlawful to sell alcoholic liquors on Sunday except as authorized by law, on Christmas Day, or during periods proclaimed by the Governor in the interest of law and order or public morals and decorum. Full authority to proclaim these periods is conferred upon the Governor in addition to all his other powers. A person who violates a provision of this section is guilty of a misdemeanor and, upon conviction, must be punished as follows:

(a)    for a first offense, by a fine of two hundred dollars or imprisonment for sixty days;

(b)    for a second offense, by a fine of one thousand dollars or imprisonment for one year; and

(c)    for a third or subsequent offense, by a fine of two thousand dollars or imprisonment for two years.”

The prohibition for selling liquor on election day was removed by Act 223 in July 2014.  Here is the section as it currently stands.
