Kathleen Folbigg pardoned and released after serving 20 years for infant deaths.

Kathleen Folbigg, who was convicted of killing her four infant children, has been pardoned after new evidence suggested they may have died naturally. A recent inquiry heard scientists believe the children shared a genetic mutation that can cause sudden cardiac death. The case has been described as one of Australia's greatest miscarriages of justice. The unconditional pardon does not quash Ms Folbigg's convictions, but if overturned, she could potentially sue the government for millions of dollars in compensation. The case shows the need for reform that makes the legal system more "science sensitive".
