"Certain forms of hate speech may be prohibited under international law, even if they do not reach the above-mentioned threshold of incitement, in specific circumstances. Under article 19 of the International Covenant on Civil and Political Rights, certain types of biased expression may be restricted if such restrictions meet certain strict conditions. Such limitations need to: (a) be provided by law; (b) pursue a legitimate aim, such as the respect of the rights of others, including the right to equality and non-discrimination, or the protection of public order; and (c) be necessary in a democratic society and proportionate (the “three-part test”)."
