The Crown's recommendation fixes the upper limits of a charge
33.20The Crown's recommendation lays down the maximum amount of a charge on public funds or on the people, as well as its objects and purposes. An amendment infringes the financial initiative of the Crown not only if it increases the amount, but also if it extends the objects and purposes, or relaxes the conditions and qualifications expressed in the communication by which the Crown has recommended a charge. Similarly, no amendment to a motion relating to Supply is in order except one which proposes a reduction in the amount sought.
If a motion for a financial resolution is amended, it is the final version of the resolution which is effective and the charge imposed may not exceed the limits so laid down.
