The question of what is public performance is of some importance, especially in Great Britain, where playright is not infringed except by representation in a place of dramatic entertainment and where it has been held that any place in which a dramatic piece is publicly performed is for the time a place of dramatic entertainment. A public performance is probably one to which the public in general is admitted either by sale of tickets or by invitation; and this would probably include a performance given before a society to membership in which the public might be admitted, although a performance limited to a certain class of the public might not be construed as a public representation. Where "Our boys" was performed at Guy's Hospital, London, by an amateur company, for nurses and others connected with the hospital specially invited, it was held in 1884, in Duck _v._ Bates, that though a performance may be public where the public are present, although no money is taken, yet the production in question was not a public representation. In this leading case, important as a precedent for America as well as in England, the decision was made by Justices Brett, M. R., and Bowen, L. J., Justice Fry dissenting, and the Master of the Rolls, in an elaborate opinion, discussed the relations of private and public performance, as a question of fact: "In order to entitle the author to penalties there must be a representation which will injure the author's right to money; such, for instance, as a representation which, although it is not for profit, would attract persons who are willing to pay money, and would induce them not to go and see a performance licensed by the author.... The representation must be other than domestic or private. There must be present a sufficient part of the public who would go also to a performance licensed by the author as a commercial transaction.... I wish to say, by way of warning, that those who go beyond the facts of the present case may incur the penalties of the statute." {Sidenote: Manuscript rights}
