The integrity of the award is upheld by the tight security and secrecy surrounding the votes. Once the umpires make their decision, the votes are locked away and transported by armoured security vehicles. No one except the three umpires knows exactly who has been voted for, and as different umpires vote on different games, no one can be sure of who will win. Unlike most award ceremonies, the votes are not tallied or even opened until they are actually announced on the night, so the drama is maintained until late on the actual night, when the result sometimes comes down to the final round of votes.
