After considerable debate on the topic, the following has been decided by the Council, on a 3 to 1 vote:
Once someone has stood for nomination, they can not be removed from the ballot. They may step down from a position once elected, and/or make their stance clear before the election so others may choose not vote for them.
good luck with your board of 5 if I'm one of them after vote
This also means there are 6 nominated candidates for Board, of which 5 will be elected via a standard election.
