1. The court observed that in trade mark non-use proceedings, where the proprietor respondent bears the onus and can be expected to have comprehensive and peculiar knowledge of use, clear and compelling evidence should be expected, and proprietors ought not to expect the evidential burden to be discharged by allegations that are sparse, ambiguous, or lacking in conviction.
2. The court noted that while the Plascon-Evans rule applies in application proceedings, courts must be vigilant not to permit abuse by unvirtuous respondents sheltering behind patently implausible affidavit versions or bald denials, particularly in proceedings where the respondent has peculiar knowledge of the facts.
3. Nugent JA commented that the absence of any documentary evidence corroborating alleged sales (no invoices, delivery notes, or accounting records) was 'remarkable', suggesting an inference that documentation was not advanced lest it reveal when alleged sales occurred, though he noted it was not necessary to find deliberate concealment.
4. On the invitation to adopt a trans-territorial approach to trade mark proprietorship, the court observed this would have implications for the country's international relations and obligations that require careful legislative consideration, not judicial intervention.
5. The court noted that trade marks are registered for use, not merely to prevent others from using them, reflecting the underlying policy of the registration system.
6. The judgment acknowledged that common law is capable of constitutional development, but distinguished this from interpretation of statutory provisions where the meaning has been judicially settled and alteration is a matter for the legislature.
