I do, and I will probably defer to Mr. Méla on the drafting.
To clarify, there would indeed be a substantial change. Right now, as drafted, facilitation could only be invoked at the joint request of the parties, meaning that if one party wanted facilitation but the other party didn't, you wouldn't meet the test for engaging the facilitation.
My understanding is that Ms. McPherson's change would allow one party or the other to potentially engage in a facilitation.
