I agree with all of your amendments (and have edited the proposal accordingly), except that I would prefer “which shall commence on” to “held on.” I agree that “held on” is a more concise, less cumbersome way of putting the point. And that’s actually how I initially drafted the section in my head. But it seems somewhat inconsistent with how our Assembly actually conducts votes. If you say that a vote is to be “held on” a particular date, that suggests to me that it commences and concludes on that date. But that’s not what will take place in this instance–our votes require a multi-day process as set out in the Legislative Procedure Act. The “commenced on” language was designed to indicate that the Chair is to launch that process on March 15, not that the entire vote must be completed on that day.
