For convenience and description, these various motions may be classified into five broad categories. A main motion brings business before the assembly. It can only be made when no other motion is pending and ranks lowest in the order of precedence of motions. Subsidiary motions fall into the order of precedence. Like subsidiary motions, the privileged motions fit into an order of precedence.
Incidental motions deal with questions of procedure arising out of other motions or business.
They have no order of precedence among themselves. Instead, they arise incidentally and are decided as they arise. These motions do not quite fit in any other category and rarely arise. They do not fit within the order of precedence and can only be made while no business is pending. Not every motion is in order at any time.
