Francis Day and Hunter Ltd v Bron: CA 1963

The test of substantial similarity in copyright infringement cases is an objective one. That assessment is for the court with such assistance from the evidence and parties as it can muster. To be an infringement there must be ‘some causal connection’ between the form of the infringing work and the form of the copyright work.
Wilmer LJ said: ‘I do not think it could be doubted that there was material on which to base the inference that the composer of ‘Why’ deliberately copied from ‘Spanish Town’. Were that the right inference, I am satisfied that the degree of similarity would be sufficient to constitute an infringement of the plaintiffs’ copyright.’ Although it was possible to demonstrate that a person had infringed copyright without intending to do so, it was nevertheless necessary to establish ‘proof of familiarity’ with the allegedly copied work, as a prerequisite to establishing infringement: and that there was a causal link between the alleged infringing work and the original work
Diplock LJ said: ‘to constitute infringement of copyright in any literary, dramatic or musical work, there must be present two elements: first, there must be sufficient objective similarity between the infringing work and the copyright work, or a substantial part thereof, for the former to be properly described, not necessarily as identical with, but as a reproduction or adaptation of the latter; secondly, the copyright work must be the source from which the infringing work is derived.’
