I do not see the need for a written rule about it, in terms of faction leaders honestly. This does not seem to be a problem with most factions as far as I can tell, and should be something left for factions to handle internally. Any good Faction leader that looses interest in the game or RL obligations are taking up more time, would most likely pass the command keys on to someone else. I can recall only one or two factions in the past, where a leader has just chosen to let an official faction die off, rather than pass on the rights to the "RP" created to someone else.
As for Mod and Admins and Devs....maybe there is some logic for a set of guidelines to be written to being able to remove people from a position if they show no activity (0) or interest in managing the community after a specific amount of time has passed.
***EDIT***
After reading the "Other" thread that started this, I can see that there are circumstances were a set of guidelines for passing over the leadership of an official faction to someone else might need to be put to ink.
The thing about rules is, that once they are there, they are sometimes then used in ways that were not intended. Setting up something to pass the keys onto someone else because of an unannounced or unexplained inactivity is one thing and may be needed.
Using those rules to oust an active but passive leader would be the thing to guard against.
Also, somewhere in the rules would have to something to the effect of moving the factions existing RP forward and not just doing a 180 degree turn on day one of a factions new leadership, and screw with other peoples invested role play and diplomacy with the former leadership.
