‘Freedom of opinion
9. Paragraph 1 of article 19 requires protection of the right to hold opinions without interference. This is a right to which the Covenant permits no exception or restriction. Freedom of opinion extends to the right to change an opinion whenever and for whatever reason a person so freely chooses. No person may be subject to the impairment of any rights under the Covenant on the basis of his or her actual, perceived or supposed opinions. All forms of opinion are protected, including opinions of a political, scientific, historic, moral or religious nature. It is incompatible with paragraph 1 to criminalize the holding of an opinion. The harassment, intimidation or stigmatization of a person, including arrest, detention, trial or imprisonment for reasons of the opinions they may hold, constitutes a violation of article 19, paragraph 1.
10. Any form of effort to coerce the holding or not holding of any opinion is prohibited. Freedom to express one’s opinion necessarily includes freedom not to express one’s opinion.
Freedom of expression
11. Paragraph 2 requires States parties to guarantee the right to freedom of expression, including the right to seek, receive and impart information and ideas of all kinds regardless of frontiers. This right includes the expression and receipt of communications of every form of idea and opinion capable of transmission to others, subject to the provisions in article 19, paragraph 3, and article 20. It includes political discourse, commentary on one’s own and on public affairs, canvassing, discussion of human rights, journalism, cultural and artistic expression, teaching, and religious discourse. It may also include commercial advertising. The scope of paragraph 2 embraces even expression that may be regarded as deeply offensive, 22 although such expression may be restricted in accordance with the provisions of article 19, paragraph 3 and article 20.
12. Paragraph 2 protects all forms of expression and the means of their dissemination. Such forms include spoken, written and sign language and such non-verbal expression as images and objects of art. Means of expression include books, newspapers, pamphlets, posters, banners, dress and legal submissions. They include all forms of audio-visual as well as electronic and internet-based modes of expression.‘
