Officers- The President!

Presidential Duties!

There are four constitutional officer positions that are typical for organizations. The four officers include the president, vice president, secretary, and treasurer. The Chairman is also the President of an organization and has multiple duties, which is why a vice president is necessary in order to assist the president in maintaining order!

The duties of the President include:
1) To open the meeting at the appointed time by taking the chair and calling the meeting to order, having ascertained that a quorum is present. [RONR 11th ed. pg. 449, l. 24-26]
2) To announce in proper sequence the business that comes before the assembly or becomes in order in accordance with the prescribed order of business, agenda, or program, and with existing orders of the day. [RONR 11th ed. pg. 449, l.27-30]
3) To recognize members who are entitled to the floor. [RONR 11th. ed. pg. 449, l. 31-32]
4) To state and to put to vote all questions that legitimately come before the assembly as motions or that otherwise arise in the course of proceedings (except questions that relate to the presiding officer himself in the manner noted below, and to announce the result of each vote; or if a motion that is not in order is made, to rule it out of order. [RONR 11th. ed. pg. 449-450, l.33-4]
5)  To protect the assembly from annoyance from evidently frivolous or dilatory motions by refusing to recognize them. [RONR 11th. ed. pg. 450, l. 7-8]
6) To enforce the rules relating to debate and those relating to order and decorum within the assembly. [RONR 11th. ed. pg. 450, l. 9-11]
7) To expedite business in every way compatible with the rights of members. [RONR 11th. ed. pg. 450, l. 12-13]
8) To decide all questions of order, subject to appeal- unless, when in doubt, the presiding officer prefers initially to submit such a question to the assembly for decision. [RONR 11th. ed. pg. 450, l. 14-17]
9) To respond to inquiries of members relating to parliamentary procedure or factual information bearing on the business of the assembly. [RONR 11th. ed. pg. 450, l. 18-21]
10)  To authenticate by his or her signature, when necessary, all acts, orders, and proceedings of the assembly. [RONR 11th ed. pg. 450, l. 22-23]
11) To declare the meeting adjourned when the assembly so votes or- where applicable- at the time prescribed in the program, or at any time in the event of a sudden emergency affecting the safety of those present. [RONR 11th. ed. pg. 450, l. 24-27]

Fun Fact/ Question:

Q1:
Is it true that the president can vote only to break a tie?

Answer:
No!  If the president is a member of the voting body, he or she has exactly the same rights and privileges as all other members have, including the right to make motions, to speak in debate, and to vote on all questions. (Example- small boards)
