45. Amendments of Rules of Order. These rules can be amended at any regular meeting of the assembly, by a two-thirds vote of the members present, provided the amendment was submitted in writing at the previous regular meeting. And no amendment to Constitutions or By-Laws shall be permitted, without at least equal notice and a two-thirds vote.* [Constitutions, By-Laws and Rules of Order should always prohibit their being amended by less than a two-thirds vote, and without previous notice of the amendment being given. If the By-Laws should contain rules that it may be desirable to occasionally suspend, then they should state how they can be suspended, just as is done in these Rules of Order, § 18. If there is no such rule it is impossible to suspend any rule, if a single member objects.
