Australian Electoral Commission Refuses To Release Vote Counting Source Code

angry tapir writes: The Australian Electoral Commission has been fighting a freedom of information request to reveal the source code of the software it uses to calculate votes in elections for Australia's upper house of parliament. Not only has the AEC refused an FOI request (PDF) for the source code, but it has also refused an order from the Senate directing that the source code be produced. Apparently releasing the code could "leave the voting system open to hacking or manipulation."
