Open Meetings Law and Robert's Rules of Order

A member library has the following questions concerning libraries that are subject to Open Meetings Law (OML) and have adopted Robert’s Rules of Order for their meetings:
1. Are consent agendas allowed for agencies subject to OML?
2. Should public or association libraries refrain from having their Boards of Trustees accept the financials (motion, second, vote) presented by the library’s treasurer so as not to give the appearance of agreement and assurance that they are accurate and without error?
3. If there is a board committee that, per the bylaws, is not given the power to act independently o[f] the board, is it permissible for a member of such a committee to make a motion to be followed by discussion and vote without a second?
4. From the perspective of OML or others that you know are relevant for the library is it legally acceptable for a board chair to make a motion?
