I was just mentioning that, if my memory serves me well, there was a new Standing Order adopted in 2015 by the House that provides that, in the event that a private member's bill is judged out of order by the Speaker of the House, either because it needed to be preceded by what we call a ways and means motion when there's a taxation purpose included in the bill, or for any other procedural reason, there's a time frame that is provided for the member in question to actually substitute the item that he or she had that was found to be out of order and replace it with another item of his or her choice. Basically, the member doesn't lose his or her spot.
