When the bill is reported to the House, there will be two possible options.
If the problem is with the royal recommendation, the Speaker will act on his own; he has no choice. If he considers that this clause causes a problem with the royal recommendation, he will make that decision and remove the clause from the bill.
If there is no problem with the royal recommendation, it will depend on whether a point of order is raised. If that is the case, the Speaker will examine the arguments and make a decision. So similarly, if he decides that the amendment is out of order, it will be removed.
