What is a proxy and when might I need one?
Any member who is entitled to attend and cast a vote at a meeting of members may appoint a person as their proxy to attend the meeting and vote on their behalf (if, for example, the member is unable to attend the meeting). A proxy appointed to attend and vote for a member has the same rights as the member to speak at the meeting and to vote.
