When you draft a bill and include definitions for interpretive purposes—and, in a way, they are the meat and potatoes of the bill—it's to indicate that the bill deals with this or that matter, which are to be defined and interpreted in a specific way. Agreements have been negotiated, they are included in the bill drafted by the government and, in the meantime, another agreement is negotiated but nobody thinks of including it.
That seems rather odd to me, because it basically means that we sign agreements and draft a bill at the same time without necessarily making the important connection between the two. As the term suggests, these are related agreements, which means there is an important cause-and-effect relationship between the bill and the Agreement. That means that the bill as a whole—even if an amendment were brought forward today to include it, it would simply be an amendment that is tacked on—was not drafted with that Agreement in mind. That is also what this means. So, even if we pass amendments, we will have forgotten an extremely important element in drafting this bill. That means that the bill—yes, we can pass an amendment, people could propose something and we expect that they will—or that the legislation as a whole and the different clauses it includes, do not refer to that. It's rather odd and somewhat anachronistic to simply add something without actually amending any other clause in the bill. It seems a little ad hoc.
