CANBERRA, Australia – Parliament on Wednesday lifted Australia's ban on cloning human embryos for stem cell research despite opposition from the prime minister and other party leaders.
The legislation was approved by a vote of 82 to 62 in the House of Representatives. It was passed by the Senate last month.
Supporting the legislation, Defense Minister Brendan Nelson said his generation had benefited enormously from the scientific endurance and judgment of those who pioneered difficult research and legislation.
"We owe it to the next generation no less to show the same wisdom and indeed the same courage," Nelson said.
The party leaders were among the final speakers in a divisive debate which began in the lower house Monday.
"I've decided to vote against this legislation for the reason that in the end you have to take a stand for some absolutes in our society," Prime Minister John Howard told Parliament. "And I think what we're talking about here is a moral absolute and that is why I can't support the legislation."
Opposition Labor Party Leader Kevin Rudd later said he had similarly wrestled with his conscience over the legislation and decided he could not support it.
"I find it very difficult to support a legal regime that results in the creation of a form of human life for the single and explicit purpose of conducting experimentation on that form of human life," Rudd said.
Deputy Prime Minister Mark Vaile, leader of the Nationals party, and Howard's deputy in the ruling Liberal Party, Peter Costello, also gave their reasons for voting against the bill. There are no other parties represented in the 150-seat lower chamber.
All parties encouraged their lawmakers to vote according to their consciences rather than following party lines. A conscience vote is rare in Australian politics.
"We must not attempt to achieve good ends through what I believe are immoral means," Vaile said.
The House of Representatives debate came after the legislation narrowly passed through the Senate by a 34-32 vote on Nov. 7.
Scientists hope stem cell research will eventually lead to treatments for conditions including Parkinson's and Alzheimer's, as well as spinal cord injuries, diabetes and arthritis.
Parliament passed Australia's first laws on stem cell research in 2002, allowing scientists to extract stem cells from spare embryos intended for in vitro fertilization but preventing cell cloning.
The bill passed allows for therapeutic cloning, the splicing of skin cells with eggs to produce stem cells, also known as master cells, which are capable of forming all the tissues of the human body.
