Ann: Scheme Booklet, page-6

If the Scheme does not proceed, Dart intends to conduct a sale process for Dart Shareholders who hold less than A$500 worth of Dart Shares in accordance with Dart’s constitution and the Listing Rules. This will ensure small Dart Shareholders will have the opportunity to sell their Dart Shares free of brokerage costs, regardless of the outcome of the Scheme.

And it will also ensure that voting these guys out and installing a new board will be that much harder to achieve.
