843. Functions of the Crown, the House of Lords and the House of Commons.

The Crown initiates the financial work of Parliament by a demand for a grant. It is for the House of Commons to consider to what extent that demand is to be agreed to and the charges which should be put upon the people to meet it1. An Act of Parliament is necessary to validate any grant or charge, and the consideration of such a bill gives the House of Lords the opportunity of exercising its constitutional right to assent or dissent, but not to alter the grants or charges agreed to by the House of Commons.
