frreedom of speech is a principle that supports the freedom of an individual or a community to articulate their opinions and ideas without fear of retaliation, censorship, or sanction. The term "freedom of expression" is sometimes used synonymously but includes any act of seeking, receiving, and imparting information or ideas, regardless of the medium used.
Freedom of expression is recognized as a human right under article 19 of the Universal Declaration of Human Rights (UDHR) and recognized in international human rights law in the International Covenant on Civil and Political Rights (ICCPR). Article 19 of the UDHR states that "everyone shall have the right to hold opinions without interference" and "everyone shall have the right to freedom of expression; this right shall include freedom to seek, receive and impart information and ideas of all kinds, regardless of frontiers, either orally, in writing or in print, in the form of art, or through any other media of his choice". The version of Article 19 in the ICCPR later amends this by stating that the exercise of these rights carries "special duties and responsibilities" and may "therefore be subject to certain restrictions" when necessary "[f]or respect of the rights or reputation of others" or "[f]or the protection of national security or of public order (order public), or of public health or morals".
Freedom of speech and expression, therefore, may not be recognized as being absolute, and common limitations to freedom of speech relate to libel, slander, obscenity, pornography, sedition, incitement, fighting words, classified information, copyright violation, trade secrets, food labeling, non-disclosure agreements, the right to privacy, the right to be forgotten, public security, and perjury. Justifications for such include the harm principle, proposed by John Stuart Mill in On Liberty, which suggests that: "the only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others."
The idea of the "offense principle" is also used in the justification of speech limitations, describing the restriction on forms of expression deemed offensive to society, considering factors such as extent, duration, motives of the speaker, and ease with which it could be avoided.With the evolution of the digital age, application of the freedom of speech becomes more controversial as new means of communication and restrictions arise, for example the Golden Shield Project, an initiative by Chinese government's Ministry of Public Security that filters potentially unfavorable data from foreign countries.
Freedom of speech and expression has a long history that predates modern international human rights instruments. It is thought that ancient Athenian democratic principle of free speech may have emerged in the late 6th or early 5th century BC.The values of the Roman Republicincluded freedom of speech and freedom of religion.
Concepts of freedom of speech can be found in early human rights documents.England's Bill of Rights 1689 legally established the constitutional right of 'freedom of speech in Parliament' which is still in effect. The Declaration of the Rights of Man and of the Citizen, adopted during the French Revolution in 1789, specifically affirmed freedom of speech as an inalienable right.The Declaration provides for freedom of expression in Article 11, which states that:
The free communication of ideas and opinions is one of the most precious of the rights of man. Every citizen may, accordingly, speak, write, and print with freedom, but shall be responsible for such abuses of this freedom as shall be defined by law.
Article 19 of the Universal Declaration of Human Rights, adopted in 1948, states that:
Everyone has the right to freedom of opinion and expression; this right includes freedom to hold opinions without interference and to seek, receive and impart information and ideas through any media and regardless of frontiers.
Today, freedom of speech, or the freedom of expression, is recognized in international and regional human rights law. The right is enshrined in Article 19 of the International Covenant on Civil and Political Rights, Article 10 of the European Convention on Human Rights, Article 13 of the American Convention on Human Rights and Article 9 of the African Charter on Human and Peoples' Rights. Based on John Milton's arguments, freedom of speech is understood as a multi-faceted right that includes not only the right to express, or disseminate, information and ideas, but three further distinct aspects:
- the right to seek information and ideas;
- the right to receive information and ideas;
- the right to impart information and ideas
International, regional and national standards also recognize that freedom of speech, as the freedom of expression, includes any medium, be it orally, in written, in print, through the Internet or through art forms. This means that the protection of freedom of speech as a right includes not only the content, but also the means of expression.
The right to freedom of speech and expression is closely related to other rights, and may be limited when conflicting with other rights (see limitations on freedom of speech).The right to freedom of expression is also related to the right to a fair trial and court proceeding which may limit access to the search for information, or determine the opportunity and means in which freedom of expression is manifested within court proceedings. As a general principle freedom of expression may not limit the right to privacy, as well as the honor and reputation of others. However greater latitude is given when criticism of public figures is involved.
The right to freedom of expression is particularly important for media, which plays a special role as the bearer of the general right to freedom of expression for all. However, freedom of the pressdoes not necessarily enable freedom of speech. Judith Lichtenberg has outlined conditions in which freedom of the press may constrain freedom of speech, for example where the media suppresses information or stifles the diversity of voices inherent in freedom of speech. Lichtenberg argues that freedom of the press is simply a form of property right summed up by the principle "no money, no voice".
