What is necessary for a valid motion concerning new business?

For a motion concerning new business to be valid, it must indeed require a second and be debatable. This process is fundamental to parliamentary procedure, which governs how meetings are conducted in an orderly fashion. When a member proposes a motion, it is essential that another member supports it by providing a second; this indicates that at least one other person believes the motion warrants further discussion.

Once a motion has been seconded, it opens the floor for debate among members, allowing everyone the opportunity to express their views for or against the motion. This debate is crucial for ensuring that all perspectives are considered before a decision is made. The ability to discuss and refine the motion enhances the democratic process within the meeting.

The other options presented do not accurately reflect the rules regarding valid motions. While it's important for motions to be relevant, they do not need to relate to previously discussed topics. The president may facilitate discussions, but any member can propose motions. Lastly, motions do not need to be written down during the meeting; they can be verbally introduced as part of the proceedings.
