When a lawyer says "I would like to make a motion," I often interrupt to ask "What's holding you back?"

Perhaps, since you are in charge, the lawyer is asking for permission. Certainly, making a motion is not contrary to the language of Robert's Rules of Order:


A motion is a proposal that the assembly take certain action, or that it express itself as holding certain views. It is made by a member’s obtaining the floor as already described and saying, “I move that” (which is equivalent to saying, “I propose that”), and then stating the action he proposes to have taken.
