Defamation as a crime
Questions of group libel have been appearing in common law for hundreds of years. One of the earliest known cases of a defendant being tried for defamation of a group was the case of R v Orme and Nutt (1700). In this case, the jury found that the defendant was guilty of libelling several subjects, though they did not specifically identify who these subjects were. A report of the case told that the jury believed that "where a writing ... inveighs against mankind in general, or against a particular order of men, as for instance, men of the gown, this is no libel, but it must descend to particulars and individuals to make it libel." This jury believed that only individuals who believed they were specifically defamed had a claim to a libel case. Since the jury was unable to identify the exact people who were being defamed, there was no cause to identify the statements were a libel.
