Initially, rules in the 100's are immutable and rules in the 200's are mutable. This definition implies that, at least initially, all new rules are mutable. Immutable rules, as long as they are immutable, may not be amended or repealed. All rules changes proposed in the proper way shall be voted on. They will be adopted if and only if they receive the required number of votes.
Every player is an eligible voter.
Every eligible voter must participate in every vote on rule changes. Any proposed rule change must be written down before it is voted on. If adopted, it must guide play in the form in which it was voted on. No rule change may take effect earlier than the moment of the completion of the vote that adopted it, even if its wording explicitly states otherwise. No rule change may have retroactive application.
