Certainly, subsection 12(2) of the Members By-Law tells us that:
Members are personally responsible for paying expenditures
Then we go to section 19, and you have kind of a progressive process, beginning with paragraph 19(a):
If a person fails to comply with this By-law (a) the Board or the Clerk of the House of Commons acting under the authority of the Board may give written notice to the Member responsible, requiring the Member to rectify the situation to the satisfaction of the Board or the Clerk;
That's the first step.
Then,
(b) if the situation is not rectified to the satisfaction of the Board or the Clerk, the Board may order that any amount of money necessary to rectify the situation be withheld from any budget, allowance or other payment that may be made available to the Member under this By-law or the Governance and Administration By-law;
And the next step:
the Board may order that any budget, allowance or other payment that may be made available to the Member under this By-law or the Governance and Administration By-law be frozen for such time and on such other conditions as the Board considers necessary (i) if the non-compliance continues, or (ii) if the Board considers it necessary to protect House of Commons funds.
So that's the answer. I don't know if Mr. Watters wants to explain how that would be done in practice, but there is a process in the bylaws to deal with this.
