Changing these bylaws requires action from the House of Delegates, and there are two ways to do it. The first way is to bring up the change at any regular meeting and get a two-thirds vote from the delegates who are present and voting. This method lets changes happen faster, but it needs strong support to pass.
The second way takes a bit more time but needs fewer votes. The proposed change must first be presented at one meeting of the House of Delegates. Then, at the next regular meeting, it only needs a simple majority vote from the delegates present and voting to pass.
Both methods give delegates a fair say in updating the bylaws. The higher vote requirement for quick changes helps make sure that sudden decisions have wide support. The two-step process gives delegates time to think over proposed changes before voting, which can lead to more thoughtful decisions with a lower bar for approval.
