I'm sorry, I don't have the documentation, but I can speak generally to this. The double vote cases involve persons voting twice or trying to vote twice. Many of them are essentially inadvertent. There are people who think they can vote at their cottage where they have a VIC card and at their home where they got a VIC card. There are elderly people. I'm getting anecdotal, but there was a lady whose husband said to her, “It's voting day, go out and vote”, so she went out to vote and got home and remembered that she'd voted at the advance poll. She actually went back to the polling station and asked them if they could take her ballot out of the box.
So, believe it or not, there are a number of inadvertent situations of double voting that we've dealt with through caution letters.
