No amendment that is not germane to the provisions of the joint resolution or to the order issued under section 904 of this title shall be in order in the Senate. In the Senate, an amendment, any amendment to an amendment, or any debatable motion or appeal is debatable for not to exceed 30 minutes to be equally divided between, and controlled by, the mover and the majority leader (or their designees), except that in the event that the majority leader favors the amendment, motion, or appeal, the minority leader (or the minority leader’s designee) shall control the time in opposition to the amendment, motion, or appeal.

In the Senate, an amendment that is otherwise in order shall be in order notwithstanding the fact that it amends the joint resolution in more than one place or amends language previously amended. It shall not be in order in the Senate to vote on the question of agreeing to such a joint resolution or any amendment thereto unless the figures then contained in such joint resolution or amendment are mathematically consistent.

the procedure in the Senate shall be the same as if no joint resolution had been received from the House; but

the vote on final passage shall be on the joint resolution of the House if it is identical to the joint resolution then pending for passage in the Senate; or

if the joint resolution from the House is not identical to the joint resolution then pending for passage in the Senate and the Senate then passes the Senate joint resolution, the Senate shall be considered to have passed the House joint resolution as amended by the text of the Senate joint resolution.
