A special rule of order is parliamentary procedure term for a rule adopted by the organization that relate to procedure or to the duties of officers within meetings.
Special rules of order (with a few exceptions) supersede the rules in an adopted parliamentary authority such as Robert's Rules of Order. These rules continue in existence from one meeting to the next.
See main article: Robert's Rules of Order. Special rules can be adopted by a two-thirds vote with previous notice or a majority of the entire membership of the group. In conventions, a mixture of standing and special rules that are adopted at the start of the convention are called "convention standing rule" in RONR. These, when adopted as a "package" generally require a two-thirds vote. [1]
The Standard Code of Parliamentary Procedure (TSC), refer to these types of rules as "standing rules", and do not require a simple majority vote without previous notice.[2] One of the most common types of these rules is the rule to set limits on the amount of time, or the number of times, a member may speak in debate or to prohibit some type of motion.
