The “knowingly” is a mens rea element that is associated with the offence. When we try to craft legislation, we want to make sure that every offence that Parliament wants a mental element associated with has at least one of those mental elements—so it's those dual procedure offences versus strict liability offences, which don't have a huge intent criterion.
What I am saying is that in many prohibitions we already have an intent criterion. For example, in section 91 we already have the intent to affect the results of the election, and of course the person making the publication would need to know that the information that is published is false.
We already have two intent requirements here.
