I am not sure if I can find thread where it was mentioned/announced, but basically the main thread with all the house and other organization laws was locked after certain incident when faction changed their laws in an abusive way, and since then all govs have to update them through requests to the staff (I am person doing it on behalf of RheinGov whole time) which is supposed to check and approve changes. Reason why you could not notice that is that Kusari is the only house which does not have laws in that thread, only redirecting link in the OP.
