Mr. Murphy is satisfied, but I am actually not satisfied. That's why I raised the question.
If he hadn't brought the amendment forward, I probably wouldn't have noticed it, but the way it's crafted is rather confusing. It would be my humble submission that a judge could, in fact, narrowly read the lawful excuse to include only what you mention in the subsequent subsection. You may disagree, but that would be my reading on the face of it.
Mr. Murphy's original suspicion is reasonably founded, and I'm going to leave it at that. I am not satisfied that this section protects the lawful excuse defence as fully as it ought to, because of the prescription that you have in the subsection.
