So says Robert's Rules of Order - I didn't know such a thing was possible - and depending upon the charter/by-laws/constitution of the organization, it might not be:
By-laws should include all the rules that are of such importance that they cannot be changed in any way without previous notice, except those placed in the constitution and the rules of order. Few societies adopt any special rules of order of their own under that name, contenting themselves with putting a few such rules in their by-laws and then adopting some standard work on parliamentary law as their authority. When a society is incorporated the charter may take the place of the constitution, and in such a case the by-laws would contain all the rules of the society, except those in the charter that cannot be changed without previous notice. The by-laws should always provide for their amendment as shown in 68, and also for a quorum,64. If it is desired to permit the suspension of any by-law it should be specifically provided for. By-laws, except those relating to business procedure, cannot be suspended, unless they expressly provide for their suspension. By-laws in the nature of rules of order may be suspended by a two-thirds vote, as stated in 22.
