expression under international law.3 As a quick review, under international human rights
law any restriction on freedom of expression must meet the following requirements:
1) Be provided by law.
2) Protect a legitimate interest, defined as the rights or reputations of others, national
security, public order, public health or public morals.
3) Be necessary to protect that interest (which includes a proportionality requirement).
Hate Speech
Under international human rights law, States have an obligation to prohibit hate speech
which incites discrimination, hostility or violence. Article 20(2) of the ICCPR states:
Any advocacy of national, racial or religious hatred that constitutes incitement to
discrimination, hostility or violence shall be prohibited by law.
Other international treaties also require States to prohibit or respond to hate speech. The
Convention on the Elimination of Racial Discrimination (CERD) requires States to prohibit the
dissemination of ideas based on racial superiority or hatred, incitement to racial
discrimination and incitement to acts of racial violence. 4 When hate speech amounts to
incitement to genocide, it is an international crime within the jurisdiction of the International
Criminal Court, while the Genocide Convention requires States to prohibit “direct and public
incitement to commit genocide”.5 Other international standards also address hate speech,
such as the UN Declaration on the Rights of Indigenous Peoples, which calls on States to
address propaganda which promotes or incites racial or ethnic discrimination against
indigenous peoples.6
Hate speech attacks the equality of its targets, one of the most cherished of human rights. It
also inhibits the ability of impacted groups to participate freely in the public sphere,
including by freely exercising their right to freedom of expression and to access information.
Thus, while hate speech laws are a restriction on freedom of expression, they also support
the realisation of the right. When hate speech laws are properly drafted and implemented,
the right to freedom of expression and the right to be free from hatred are complementary
rather than competing rights.
