What can change the actions of any deliberative assembly?

The answer is a majority vote because in most deliberative assemblies, decisions and actions are typically determined by the will of the majority. This democratic process allows for a fair way to make decisions that reflect the preference of most members. A majority vote signifies that more than half of the voting body supports a specific action or proposal, thus legitimizing the decision made.

In parliamentary procedure, actions taken based on majority rule are foundational to effective governance and representation within an assembly. This is critical because it ensures that decisions can be made efficiently and that no single member or small group can dominate the process.

Other options, while they may play relevant roles in certain contexts, do not capture the essence of how actions are changed within a deliberative assembly the way a majority vote does. Consent from the president or approval from a parent organization may be required in specific organizations but does not universally apply to all assembly actions. Unanimous agreement of members would be ideal but is rarely practical because it requires consensus from everyone involved, making decision-making difficult and often unfeasible in larger groups. Therefore, a majority vote is the correct and most applicable mechanism for changing actions within a deliberative assembly.
