Parliamentary procedure is the body of rules, ethics, and customs governing meetings and other operations of clubs, organizations, legislative bodies, and other deliberative assemblies. General principles of parliamentary procedure include rule of the majority with respect for the minority.
The purpose of parliamentary procedure is for the assembly to conduct its businesses in the most efficient way possible while considering the rights of its members.
Members have the right to know what they are deciding on. The assembly acts on fairness and good faith. All members are treated equally. Members are expected to be of honorable character.
Each member has a vote and each vote is weighted equally. According to RONR, this rule is considered to be a "fundamental principle of parliamentary law". Exceptions to this rule, such as cumulative voting, must be expressly provided for in the organization's rules.
The decisions made by members present at a meeting are the official acts in the name of the organization. According to RONR, this rule is considered to be a "fundamental principle of parliamentary law". Exceptions for absentee voting would have to be expressly provided for in the organization's rules. Nonmembers are not allowed to vote.
Under RONR, the requirements for changing a previous action are greater than those for taking the action in the first place. A motion to rescind, repeal or annul or amend something already (previously) adopted, for instance, requires a two-thirds vote, a majority with previous notice, or a majority of the entire membership.
However, under The Standard Code of Parliamentary Procedure, a repeal or amendment of something already adopted requires only the same vote (usually a majority) and notice that was needed to adopt it in the first place.
The group must have the authority to take the actions it purports to take. To be valid, any action or decision of a body must not violate any applicable law or constitutional provision. Also, actions cannot be in conflict with a decision previously made unless that action is rescinded or amended. The body can change the rules it wants to follow as long as it follows the rules for making such changes.
Certain actions require previous notice, which protects the rights of absentees. This includes notice of the meetings. There also needs to be a quorum, or the minimum number of members to be present at a meeting.
Under RONR nonmembers have none of these rights and the assembly can exclude any or all of them from the proceedings.
