What is an essential characteristic of incidental motions?

The essential characteristic of incidental motions is that they address issues not on the agenda. Incidental motions serve to manage or clarify the procedural aspects of a meeting that arise unexpectedly or are necessary to address during the course of the meeting. These motions do not need to be included in the agenda because they pertain to immediate needs or issues that have come up while conducting business. This helps ensure that meetings remain orderly and that unforeseen complications can be dealt with effectively.

Other characteristics of incidental motions may include their ability to help facilitate discussion and decision-making without requiring prior notice or planning, which is crucial in a dynamic meeting environment. The other options do not accurately describe incidental motions, as they involve different aspects of parliamentary procedure.
