During the debate members can submit amendments to the bill under discussion. Amendments must be filed with the clerk by 10 am in the House and by noon in the Senate on the day that the bill is to be acted upon.
Amendments must be germane (relevant) to the subject matter of the bill. If chamber members think that amendments are not germane, they can request a "point of order" - it's like an objection in court. The presiding officer makes the decision, but it can be challenged and overturned by a chamber vote.
Amendments must each be voted on individually, and the ones that pass are incorporated into the final bill. Then another vote is taken on the newly amended bill as a whole. If a bill is drastically changed by an amendment, it needs to go back to the Legislative Commissioners' Office and reprinted.
The presiding officer of the chamber may determine that the amendment is technical, submission to the LCO is avoided and the bill, as amended, may be acted upon.
