Your amendment mentions an independent review, which is not the case for amendment LIB-16. There would be an overlap or redundancy if amendment CPC-8 were passed, but the review would probably be different, given that it's independent.
It is up to you to decide how you want to present your amendment. You can introduce it with changes, but the wording must be clear.
From a procedural point of view, I told the chair that the amendment could be accepted as is.
