Well, those offences in effect already import the requirement of knowledge, so we're not trying to affect those, actually. We're trying to affect all other offences where knowledge is perhaps not imported, and in those cases we are trying to say it's sufficient that the offence was committed by a person on board, whether or not identified.
So again, it's simply a drafting error in that the words “other than an offence of” were omitted. I know that's a bit difficult to follow, but that is the explanation.
