inputs: hypothesis: Only 2 people were killed during the Black Saturday bushfires. premise: THE Black Saturday bushfires royal commission, which sits for the first time today, will initially focus on the lack of warnings to communities of approaching firestorms and the Brumby Government's "stay or go" policy. But the commission, which will have only four months to produce an interim report, has already come under criticism for refusing permission for scores of survivors and the families of victims to appear before it. Individuals applying for leave to appear at the hearings have been refused permission, and told instead to lodge written submissions to the inquiry.
