Libel is a method of defamation expressed by print, writing, pictures, signs, effigies, or any communication embodied in physical form that is injurious to a person's reputation; exposes a person to public hatred, contempt or ridicule; or injures a person in their business or profession.
If someone has defamed you, you can sue them for slander. Since it falls under tort law, you can pursue your case in civil court and seek monetary damages. You must bring proof of the defamation.
Liability for libel attaches present the following elements: (a) an allegation or imputation of a discreditable act or condition concerning another; (b) publication of the imputation; (c) identity of the person defamed; and (d) existence of malice.
Slander per se is the spoken word version of libel per se—a false statement that is so obviously harmful that damage to a plaintiff's reputation is presumed. Examples of slander per se include false accusations of improper sexual conduct, criminal activity, or bad business dealings.
Defamation is a statement that injures a third party's reputation. The tort of defamation includes both libel (written statements) and slander (spoken statements). State common law and statutory law governs defamation actions, and each state varies in their standards for defamation and potential damages .
Second, libel is actionable per se (i.e. without proof of damage) whereas slander, subject to exceptions (see below), is actionable only upon proof of 'special' damage (actual damage is probably a less misleading and therefore better phrase to use though)
