What voting method does Roberts Rules of Order suggest for motions requiring a two-thirds majority?

The appropriate voting method for motions requiring a two-thirds majority, according to Robert's Rules of Order, is the rising or standing vote. This method is particularly effective for ensuring that the members' support is properly counted since it allows the chair to visibly assess the number of individuals voting in favor and against the motion.

A rising or standing vote is ideal for motions that require a two-thirds majority because it provides a clear visual representation of the level of support for the motion. In situations where important decisions are at stake, such as amending bylaws or the rules of a body, this method helps to confirm that the proposed action has the requisite level of agreement among members.

While voice votes and division votes are convenient and can be used for less contentious issues, they do not provide the same level of certainty when determining whether a two-thirds majority has been achieved. A ballot vote, while anonymous and useful for sensitive issues, typically does not lend itself well to motions needing immediate physical count verification, especially in larger assemblies. The rising or standing vote allows for a quick and accurate determination of a two-thirds majority in a straightforward manner.
