I did a search and was surprised there have been very few threads on this topic. I'm curious what others think about how it works, specifically how its membership is selected. So the most common fanon idea seems to be the hereditary "Lords and Ladies" Wizengamot, where selected by some process (usually age and/or wealth), families gain a seat on it which is passed through the family some how. While I used to be ambivalent to the concept, I now feel the need to specifically reject it. In the magical world, what really matters is the power you possess, and not money or the power your ancestors had. For example there is no evidence Dumbledore comes from a long line of distinguished wizards or that he is wealthy, yet he is Chief Warlock of the Wizengamot, which presumably is second only to the Minister of Magic for power (a position he refused). How did he get it? While he does seem politically quite capable, he never had much luck out-manoeuvring Malfoy when it came to Fudge. I can therefore only believe his power comes from his defeat of Grindelwald and his general mastery of several magical arts. Which comes to how I suspect the Wizengamot is chosen; lifelong/indefinite-length elected appointments. Baring death, resignation or forced removal you're on the Wizengamot as long as you like. If magical prowess is how you get elected and your prowess doesn't ordinarily wane with age (in fact, it becomes greater as you gain more knowledge), why wouldn't you stick around? There's definitely a process for removal though, as evidenced by Dumbledore's sacking. Presumably to deal with witches and wizards who are losing their minds due to age and such. Of course, in addition to this, it is clear there are voting Ministerial appointments to the Wizengamot as well as evidenced by Fudge, Umbridge and Bones voting at Harry's trial. Ideas? Tell me I'm horribly wrong and should leave?
