That is reasonable. The best I can offer is to keep an eye out for what he says, and I can let other Law Committee members be aware as well. If it happens, or from your perspective, when it happens again, step will be taken.

I have already mentioned to him that such comments can make things difficult to the rest of the Law Committee, so maybe he will be reasonable to that.
