§ 4. Amendments. a. A non-sponsor may move to amend a bill at any time prior to the completion of its third reading provided that at least two hours before the time for the Senate to convene, a copy of the proposed amendment or amendments to any bill on the list of bills compiled under subdivision a of section six of this Rule has been served upon the sponsor of the bill, and filed with the Journal Clerk. If a sponsor does not accept such amendment, the question shall be put to the house whether a majority of members elected vote in favor of the non-sponsor motion to amend, and such motion shall pass only if a majority of members elected vote aye. If the sponsor accepts the amendment, such amended bill shall be ordered printed without a vote, debate or explanation, and such bill shall retain its place on the Third Reading Calendar. b. If a majority of members elected vote in favor of the non-sponsor motion to amend, the sponsor of the bill may make a motion to withdraw their name from sponsorship to be substituted by a co-sponsor or the Senator who moved to amend the bill. c. The introducer of any calendar bill may offer an amendment or amendments to such bill and such amendment or amendments shall be accepted and the bill ordered printed without a vote, debate or explanation, provided, however, that in such case such bill may be recommitted by the chair of the standing committee that reported such bill and such recommittal shall also be without a vote, debate or explanation.
