The supplementary estimates are referred to the committee until three days before the last allotted day in the period, or three days before the last sitting day in the period. The reason is that it's dependent upon when the last allotted day is decided. Unfortunately, we don't know when that will be. That's the prerogative of the government, which has not decided when that last day will be.
When that last day is designated, three days before then, the order of reference for the supplementary estimates will lapse. In the event that it's not determined, the reason we have the other caveat of three days before the last sitting day is in case the government gets to within that being the last sitting day. There has to be a deadline that kicks in.
Suffice it to say that we don't actually know the deadline on that. We know that the period ends on March 26. We know that at least three sitting days before that date, it will lapse. It may lapse earlier than that. The committee can, however, study the subject matter of it under its general mandate under the Standing Orders.
I would suggest that in the calendar time that we're dealing with now, we don't have a whole lot of time, frankly, to do this before March 26th, as there are some break weeks coming up. The committee may want to take that into consideration when considering its schedule of when it wants to do its business.
