Committee motions require a second if the committee consists of how many people?

In a committee, if it consists of one person, a second to the motion is not necessary. This is because a single member can make decisions independently without needing additional support, as there is no need for a broader consensus. In the context of parliamentary procedure, the requirement for a second is to ensure that the motion is not just a solitary opinion but has the backing of at least one other member, which is critical when the committee size is larger.

For committees consisting of two or more members, the expectation is that a second be provided to help ensure that there is sufficient interest and support for a motion before it is discussed. Hence, in this case, the requirement for a second specifically applies when the committee has more than one member.
