The following is from the (London) 1888 Ordinances of the First Order of the Golden Dawn in the Outer (GH Fraters Nom Omnis Moriar (W.W. Westcott) and Deo Duce Comite Ferro (S.L. Mathers). I consider this the most dangerous bylaw that you can put into the system; ironically, it is the one that is most likely to be included because leaders like it and the myth that it supports.
18. The GH Chiefs of the Second Order reserve themselves the right to make any alterations in these Ordinances, and also to suspend the operation of either of them in any case by means of a Dispensation.
In other words, the GH Chief(s) makes all the rules, and the rules can change whenever they decide that the rules are getting in the way of whatever they want to do.
