This thesis was written for the purpose of researching how it is desirable to standardize hate speech in Korea. There are differences in the way European countries such as Germany, France, and the United Kingdom regulate hate speech in the United States, Canada, and Japan. In Germany, France, and Canada, hate speech is punishable under the “Criminal Code”. In addition, the UK and Canada regulate hate speech as part of ‘harassment’ under the Equality Act 2010 and the Canadian Human Rights Act, respectively. Then, in what ways should Korea regulate hate speech in each country in the world? In Korea, where there are defamation of facts, defamation of false facts and insults under the 「Criminal Law」, it is concerned that the restriction of the freedom of expression will be weakened by the 「Criminal Law」. Also, on December 30, 2021, the Republic of Korea recently submitted the ‘Basic Act on Human Rights Policy’ jointly with the Ministry of Justice and the National Human Rights Commission. However, it is difficult to say that it is desirable to ask if, in the future, provisions related to hate speech can be placed in laws that are fundamental to human rights such as the United Kingdom and Canada. Because, as one study shows that 80% of hate speech can be reduced even if it is left to the platform"s self-regulation, it is desirable that hate speech online go in the direction of self-regulation. However, offline hate speech regulation is not unnecessary. Even in the United States, where it is predicted that it is almost impossible to regulate hate speech in laws with the nature of the Basic Human Rights Act, offline hate speech is indirectly regulated as part of harassment through various federal and state anti-discrimination laws and precedents. In Korea, as well as the 「Act on the Prevention of Discrimination against Persons with Disabilities」, the 「Labor Standards Act」 and 「Basic Education Act」 have provisions against discrimination against various target groups. However, the legislation is insufficient to believe that hate speech can be regulated by this article. In addition, other than labor and education, legislation on anti-discrimination has not been sufficiently prepared in each area such as ‘supply of goods and services’ or ‘enforcement of laws and policies’. On the other hand, it is most appropriate to set the subject of hate speech related norms as "ethnic, race, and religion" in accordance with the 2011 Special Rapporteur"s Report on the Protection and Promotion of Freedom of Mind and Expression, as Korea ratified the International Covenant on Civil and Political Rights. In addition, regarding the content and effect of a certain expression that can be regulated as hate speech, it is said that ‘insults’, ‘depreciation’, ‘slander’, and ‘hate’ can be placed as the requirements for the content of hate speech. And, among the various ways of regulating the effect of expression, Article 20(2) of the International Covenant on Civil and Political Rights defines ‘discrimination’, ‘hostility’, ‘violence’ is specified. Finally, it concluded that hate speech would be regulated only when negative effects(discrimination, hostility, violence, etc.) in a strict sense can be recognized. ‘political expression’ and ‘remarks for academic, artistic, scientific purposes’ should be an exception to the application of the hate speech regulation clause.
