A. When a retirement bill having a fiscal impact has had an actuarial investigation pursuant to Section 3109 of this title, the bill may be considered at the next regular session of the Legislature. If the bill as originally introduced was not changed by the committee and the original version was submitted to the Legislative Actuary for an actuarial investigation, then the original version of the bill is the only one, except as otherwise provided by subsection B of this section, which may be considered by the committee or by the House of Representatives or the Senate. If the original bill was substituted by the committee and the substitute version was the one submitted to the Legislative Actuary, then that substitute bill is the only one, except as otherwise provided by subsection B of this section, which may be considered by the committee or by the House of Representatives or the Senate.

B. After completion of an actuarial investigation, any amendment to a retirement bill having a fiscal impact shall be out of order and shall not be allowed either by a committee or by the House of Representatives or the Senate, except for a nonfiscal or a reduction in cost amendment. Any amendment to a retirement bill having a fiscal impact shall be submitted to the Legislative Actuary by the chair of the committee, if a committee amendment, or by the presiding officer of the Senate or the House of Representatives if the amendment was made by the Senate or the House of Representatives. If the Legislative Actuary certifies in writing that the amendment is a nonfiscal amendment or if the amendment results in a reduction in cost and the Legislative Actuary provides an actuarial investigation as required in subsection A of Section 9 of this act,¹ then the bill as amended, with the Legislative Actuary's certification or actuarial investigation attached to the original of the amendment, may continue in the legislative process. If the Legislative Actuary will not issue such a certification for the amendment or if there is no actuarial study showing the reduced cost of the amendment, the bill's progress in the legislative process will end, and the bill shall not be considered further by either the House of Representatives or the Senate.

C. An amendment to a retirement bill having a fiscal impact which is prohibited by subsection B of this section may be withdrawn by the committee which made the amendment, if a committee amendment, or by the Senate, if that body made the amendment, or by the House of Representatives, if that body made the amendment. If the amendment is withdrawn, the bill may continue in the legislative process as any other bill, unless it is subsequently amended, and, in that event, this section shall apply to the subsequent amendment.
