Moseneke J observed that the proper test for interpreting the meaning of allegedly infringing expression should consider 'the impression created to a notional customer of average intelligence, viewing the marks as a whole or looking at the dominant features of each mark'. However, he expressly refrained from making findings on various fair use arguments, the interpretation of the specific message on the T-shirts, whether it constituted parody, and whether alternative means of expression were available, as these issues became unnecessary once it was established that no economic harm had been proven. Sachs J in his concurring judgment extensively discussed the nature and importance of parody, noting it is 'inherently paradoxical' - both original and parasitic, creative and derivative. He observed that parody is not a separate defence but an element in overall analysis. Whether expression is primarily communicative or primarily commercial is relevant. The mere fact that expressive activity has a commercial element should not be determinative. The fact that a message could be conveyed by other means should not be decisive - 'the medium could well be the message'. The context of use matters greatly - lampoons on T-shirts worn by irreverent young people is a relevant context. Courts should be extremely reluctant to evaluate parody based on whether they consider it funny or in good taste. Sachs J warned against the 'chilling effect' of overzealously applied trade mark law on free circulation of ideas, noting that large businesses with famous trade marks 'exert substantial influence over public and political issues, making them and their marks ripe and appropriate targets for parody and criticism'. He emphasized that 'humour is one of the great solvents of democracy' and that protecting subversive humour, even when commercial, serves important constitutional values.
