In Queensland you can write a Motion for a committee member’s removal for an AGM or a EGM. You don’t even need to specify why. No doubt you’d probably need to sell that with genuine, persuasive information in your accompanying info to help sell it but the Motion itself can be quite brief and to the point. I imagine these days that is intended as a dignified way to seek someone’s departure should they be older and losing their marbles without having to spell that out. But you can also use it if you have the numbers to ditch anyone rusted on or over-lording whom many don’t consider working in everyone’s favor. It’s a good rule as in Queensland committee members can just go around again unchallenged once they are on the committee in the first place, and so some do way beyond their use by date!
