Mr. Chair, it's technically not necessary. The parenthetical expressions are for clarity purposes only. They do not have substantive effect. The reason they weren't included in the original draft for that clarity is that it's the policy of the Department of Justice drafters that only when the substantive provision is opened before a proposed amendment are the clarifying provisions then changed. So there is no problem from a technical perspective in doing this. That's just the explanation as to why it wasn't done in the first place. The effect with or without them is the same.
