Under "Robert's Rules of Order" an assembly may move to commit to the committee of the whole, or simply to go into a committee of the whole at the suggestion of the presider and without objection. Upon a successful motion to go into a committee of the whole, the presiding officer designates a member to preside over the committee and yields the chair. The committee may proceed on the referred subject by debating it, considering amendments, or adopting recommendations. To conclude its proceedings, the committee votes to "rise and report." The presiding officer of the assembly then resumes the chair and accepts a report from the presiding officer of the committee. The more relaxed committee debating rules are enforced, for examples, Members may speak on a question more than once in a committee of the whole, but members who have not already spoken have priority. While sitting as a Committee of the Whole, an assembly can consider only that matter (or matters) referred to it: Unrelated motions are out of order.
