Vivier JA made obiter observations regarding the reasonableness of the physical contact requirement. The Judge suggested that even if the regulation were intra vires, it might be invalid for unreasonableness due to unequal discrimination. He postulated a hypothetical scenario where a negligent driver of an unidentified vehicle swerves onto the incorrect side of the road, just scraping one oncoming car but missing a second car altogether, yet forcing both vehicles off the road. To exclude compensation in one case but not the other based solely on physical contact could constitute such unequal discrimination as to be unreasonable, as the legislature could never have intended to authorize such a result. However, the Court found it unnecessary to decide this point given the finding of ultra vires on other grounds.
