Thank you, Mr. Chair. The idea here is if there is a change in material, a material change, and that shifts the -- let's use the example of an agreement signed, an agreement that's authorized, that's signed pursuant to a land rights agreement that has been accepted by the Minister. There's a change in material circumstances. I see where you are going, Mr. Chair. Does this just mean that an agreement can be amended if it's brought forward as changed, or does this mean the regulations will be drafted in a way that the government can force changes, if the government notes a change in material circumstances? Who's driving this? Is it the two parties who signed the agreement, or is it the government through its regulations? Thank you, Mr. Chair.
