On 29 September 2010 the Leader of the Australian Greens, Senator Bob Brown, introduced the Restoring Territory Rights (Voluntary Euthanasia Legislation) Bill 2010 into the Senate. All political parties have granted their senators and members a conscience vote on this legislation. This is the first conscience vote in the federal parliament since the Prohibition of Human Cloning for Reproduction and the Regulation of Human Embryo Research Amendment Bill was debated in 2006.
