English language is not an official language of Korea, and hence one must refer to translations in order to examine Korean laws.
There are several websites that provide English versions of Korean laws. Here are some examples:
Ministry of Government Legislation: http://www.moleg.go.kr/english/korLawEng
Statutes of the Republic of Korea: http://elaw.klri.re.kr/eng_service/main.do
