"casual vacancy "means a vacancy in a position on the board to which a board member is elected rather than appointed if the vacancy has happened otherwise than because—

(b) the term for which the board member was elected has ended; or
(c) there has been a complete or partial failure of an election.
"closing time for applications"—see section 65 (2) (Candidates for casual vacancy).
"former board member", in relation to a casual vacancy in a position on the board, means the person who was elected to the position at the last election before the vacancy happened.
"partial failure", of an election, means that fewer candidates were nominated for the election than were required to be elected.
