Cases were cited to me from passages in judgments dealing with marks held to be, or held not to be, by reason of similarities, deceptive or confusing. I have read these cases, and others. I do not think I need discuss them. The governing principles are not in dispute; and little is to be gained by the quotation of enunciations and elaborations of them in other cases. The difficulty is always in their application to the facts of the case in hand. There are, however, a few observations I would make about item (a) in s. 28. It refers to an objective quality of the mark, "likely to deceive or cause confusion". A mark is "likely to deceive" - or in the words of s. 62 is "deceptively similar", which by s. 6 (3) means the same thing - because of its inherent tendency in use, independently of the purpose or intent of the user. That is to say a mark can be deceptive without being used deceitfully. The word "deceive", I take it, here has one of the meanings in the Oxford Dictionary, "to cause to believe what is false, to lead into error". This accords with Dr. Johnson's statement of its primary sense, which was given as "to cause to mistake, to bring into error". Lord Diplock, then Diplock L.J., said in the recent Berlei v. Bali Case [1] in the Court of Appeal that: "Unlike "to deceive", "to cause confusion" does not necessarily connote any intentional misrepresentation on the part of the user." With great respect for his Lordship's opinion, I doubt whether, in their context in relation to deceptive trade marks, the words "to deceive" necessarily predicate intentional misrepresentation. However, it is unnecessary to pursue this question, because the words "or to cause confusion" appear in s. 28 and in s. 6 (3). They apparently denote an alternative, differing from "to deceive". Under the earlier Act confusion was not expressly mentioned. It was then considered that a probability of confusion would establish that a mark was likely to deceive. The question of deceptiveness could, it was then said, be judged by asking whether "there will be a confusion in the mind of the public which will lead to confusion in the goods": per Lord Parker (then Parker J.) in Re Pianotist Co.'s Application [2] , a passage quoted in this Court in Cooper Engineering Co. Pty. Ltd. v. Sigmund Pumps Ltd. [3] .
