I have difficulty with the statement that says “unless a substantive motion relates directly to business then under consideration”. How do you define this? It could be defined very confusingly. You might have some housekeeping business, for example. Does that mean that any motion can be broadly defined and can be brought in and well under the 48 hours' notice? In other words, is it necessary to have that?
I would make a suggestion to delete that section, “unless the substantive motion relates directly to business then under consideration”. There are other ways and means to bring a motion forward, under unanimous consent, for example. I think that statement in there can be confusing and can be opened up to being too broadly interpreted and could be disruptive.
