Anything's possible by unanimous consent. The rules are, however, that once you've taken a decision on the wording, which you already had, you can't amend something that's already been agreed to by committee. So the word “law” has already been agreed to, in replacing that from “convention”.
However, if you wish, by unanimous consent, to allow Ms. Duncan to move her other amendment, I would be more than happy to entertain it.
Do I have unanimous consent?
I see heads nodding; I don't see any nays.
Ms. Duncan, you have the floor. You can do it as you see fit.
