Yes. The clauses can be rather large.
The entire amendment would cause a change on page 11 and on page 12. Mr. McLean's amendment would delete paragraph (b), which is the portion that would make changes to the current page 12. You'll see that at the bottom of the page it introduces a new subclause, subclause 1(24): “Subsection (18.1) is deemed to have come into force on March 15, 2020.”
That's the aspect of the amendment that causes the retroactive application of the new provisions, and that's what Mr. McLean's amendment seeks to delete.
