I can try.
My understanding of the difference between Ms. May's and Mr. Donnelly's amendments is that Ms. May is proposing to have a regulation that prohibits a number of activities and Mr. Donnelly would like to entrench that in the act. So at the end of the day the result is the same. One is done by regulation and the other is done by the act, except for paragraph (e), which is not included in yours.
It's a question of which the committee prefers, without (e) or with (e), basically, or regulations versus the act.
