Thank you for the question.
As we've said, in general it is open to Parliament to legislate however it sees fit. The scheme of the act, for example, currently has an interpretation section, which is definitions that apply throughout the act. It's my recollection that this specific substantial connection definition is included in that interpretation section or that it will be.
If there is an interest or an intention, the way the act is structured right now, you have interpretation provisions that apply throughout. I can't think whether, off the top of my head, there are other specific definitions in other pieces, but of course if there were a term that only applied in one section of the act, that would be specified in that one section.
The scheme of the act is set up to have a general definition section and then specific provisions in other areas, if that's helpful.
