Whenever any committee of either house reports any bill which is required by this Act to have a long-term debt note with an amendment or whenever any bill is amended on the floor of either house in such manner as to substantially affect the impact of the bill on the State's debt service capacity, the Commission on Government Forecasting and Accountability shall upon request by any member of the house by which the bill is being considered prepare a new or revised State Debt Impact Note in relation to the amended bill. Copies of each new or revised State Debt Impact Note shall be furnished to the persons named in Section 2.
Whenever any member of either House is of the opinion that a State Debt Impact Note should be prepared on any bill and such note has not been requested, the member may at any time before the bill is moved to third reading request that such a note be obtained, in which case the bill shall be submitted to the Commission on Government Forecasting and Accountability for preparation of the note. If the sponsor is of the opinion that a long-term debt note is not required, the matter shall be decided by majority vote of those present and voting in the House of which he is a member.
