South Australia's parliament has rejected voluntary euthanasia. But the Australian Greens' author of the bill, Mark Parnell, still believes voluntary euthanasia laws will be passed in SA "one day". Mr Parnell's voluntary euthanasia bill was defeated in the Upper House by a vote

of 11 to nine late on Wednesday, with one politician abstaining. "To have the bill voted down is such a big disappointment," Mr Parnell said on Thursday.

"Yet to come so close is a sure sign that one day, very soon, the South Australian parliament will pass death-with-dignity laws.

"This is by no means the last time the issue will come before the Upper House." If passed, the bill was to have gone to parliament's Lower House for a vote to determine if it became law.

Mr Parnell said he would now work with voluntary euthanasia advocates with a view to presenting a revamped bill after the state election in March next year.
