I think there's always room for improvement in terms of the language of these kinds of bills. I would say that the goal we should be aiming for is not to include less plain language; I think plain language is good. We want our public law to be accessible to all members of society, and plain language helps us get there.
That said, I do agree that additional definitions could be helpful, and I think Mr. Rosborough points to that in the article that he submitted to the clerk.
