ridicule is not material. If the language is such that others, knowing the circumstances, would reasonably think it defamatory of the person complaining of and injured by it, then it is actionable."
In many cases of libels which affect the victim chiefly or solely in his office or vocation their tendency to cause injury is so clear that proof may be unnecessary. Thus, to import insanity or incompetency to a professional man, or that a public official is dishonest and corrupt is actionable. And when a libelous publication is directed against a class or body of persons, for example, the medical staff of a public hospital, any member of the body may maintain an action for the wrong.
A corporation has no character like a natural person to defend, but a defamatory charge which directly affects its credit and injures its business reputation is an actionable one. On the other hand as a corporation must transact its business and perform its duties through natural persons it is now well settled that a corporation is liable in damages for slander, as it is for other torts.
Slanderous words that are actionable have been thus classified by the United States Supreme Court: "(1) words falsely spoken of a person which impute to the party the commission of some criminal offense involving moral turpitude, for which the party, if the charge be true, may be indicted and punished; (2) words falsely spoken of a person which impute that the party is infected with some infectious disease, where, if the charge is true, it would exclude him from society; (3) defamatory words falsely spoken of a person which impute to the party unfitness to perform the duties of an office or employment of profit or the want of integrity in the discharge of his duties of such office or employment; (4) defamatory words falsely spoken of a party which prejudice such party in his or her profession or trade."
The damages may be either nominal, one dollar is often given in such cases, or compensatory, larger damages, as a punishment. The amount rendered is within the province of the jury, but courts do not hesitate to modify or set aside verdicts which are deemed excessive or too meager.
The defenses in such actions may be briefly described.
