Calumny

Defamation—also calumny, vilification, and traducement—is the communication of a false statement that harms the reputation of an individual person, business, product, group, government, religion, or nation.

Under common law, to constitute defamation, a claim must generally be false and must have been made to someone other than the person defamed. Some common law jurisdictions also distinguish between spoken defamation, called slander, and defamation in other media such as printed words or images, called libel.

False light laws protect against statements which are not technically false, but which are misleading.

In some civil law jurisdictions, defamation is treated as a crime rather than a civil wrong. The United Nations Human Rights Committee ruled in 2012 that the libel law of one country, the Philippines, was inconsistent with Article 19 of the International Covenant on Civil and Political Rights, as well as urging that "State parties [to the Covenant] should consider the decriminalization of libel".

A person who defames another may be called a "defamer", "libeler", "slanderer", or, rarely, "famacide".

The common law origins of defamation lie in the torts of "slander" (harmful statement in a transient form, especially speech) and "libel", each of which gives a common law right of action.

Defamation is the general term used internationally, and is used in this article where it is not necessary to distinguish between "slander" and "libel". Libel and slander both require publication. The fundamental distinction between libel and slander lies solely in the form in which the defamatory matter is published. If the offending material is published in some fleeting form, as by spoken words or sounds, sign language, gestures or the like, then it is slander.
