Any member of the committee can move an amendment on the floor during clause-by-clause. The deadline will still apply to any non-members of the committee, but for members of the committee who do miss that deadline, it will just mean that their amendment may not be included in the package of amendments that is prepared by the legislative services. They still have the right to bring an amendment to the floor during clause-by-clause.
