A magistrate in South Carolina has ruled that a state statute prohibiting underage alcohol sale, consumption, and possession is unconstitutional. At the heart of the matter is Article 17, Section 14 of the SC Constitution (emphasis added):
SECTION 14. Citizens deemed sui juris; restrictions as to sale of alcoholic beverages.
Every citizen who is eighteen years of age or older, not laboring under disabilities prescribed in this Constitution or otherwise established by law, shall be deemed sui juris and endowed with full legal rights and responsibilities, provided, that the General Assembly may restrict the sale of alcoholic beverages to persons until age twenty-one. (1973 (58) 864; 1975 (59) 13.)
Section 2. The transportation or importation into any State, Territory, or possession of the United States for delivery or use therein of intoxicating liquors, in violation of the laws thereof, is hereby prohibited.
In WA underage possession and consumption is prohibited:
§ 66.44.270. Furnishing liquor to minors -- Possession, use -- Penalties -- Exhibition of effects -- Exceptions
...
(2)(a) It is unlawful for any person under the age of twenty-one years to possess, consume, or otherwise acquire any liquor. A violation of this subsection is a gross misdemeanor punishable as provided for in chapter 9A.20 RCW.
(3) Subsections (1) and (2)(a) of this section do not apply to liquor given or permitted to be given to a person under the age of twenty-one years by a parent or guardian and consumed in the presence of the parent or guardian. This subsection shall not authorize consumption or possession of liquor by a person under the age of twenty-one years on any premises licensed under chapter 66.24 RCW.
And I'm sure that if you started giving little Jimmy his morning bowl of Whisky n' Cheerios, Child Services would be on your case.
The South Carolina case is being appealed. I'm sure they'll find a reason to reverse.
