During a meeting of SRC most of the voting required follows a simple process - the Chair of SRC will ask for a show of hands from those who are for, against and abstain from a particular motion or question that SRC have to vote on. If you are not sure on an issue, or do not feel comfortable, then by abstaining you are not part of the total votes that are counted.
Most commonly only a simple majority is needed to settle an issue, however in some rare cases a two thirds majority will be needed, such as appointing a trustee. The Chair will let SRC know this before the vote takes place. If the vote is too close to call, then the Chair and a staff member of Abertay SA will ask people to keep their hands up whilst each vote is counted and an anonymous record of this is kept in the minutes.
In the case of a tie, the Chair will have the deciding vote. If a member of SRC disagrees with the Chair on how a particular vote has been called - for or against - then they can to use House Rule 6 (read here for more information (Section 10)), which means a formal recorded count can be carried out.
