AUSTRALIA -- What was supposed to be a straightforward cash deal to carry a child for desperate parents has turned into an international spat over who said what, and exposed the darker side of a business credited with creating happiness for many couples.
At the center of the debate is Gammy, a seven-month-old Down Syndrome baby with a congenital heart condition who is currently receiving treatment for a lung infection at a private hospital in Thailand.
For days, Gammy's surrogate mother, 21-year-old Thai food stall worker Pattharamon Chanbua, has been telling local and foreign press that the couple abandoned their son, taking home his healthy sister.
After initially denying they knew about baby Gammy, a friend of the couple issued a statement to a local Australian newspaper saying the pair only left Gammy because they were told he was likely to die.
"Gammy was very sick when he was born and the biological parents were told he would not survive and he had a day, at best, to live and to say goodbye," the unnamed friend told the Bunbury Mail, in Western Australia, where the couple live.
Fear and lies
The friend said the surrogate mother gave birth at a different hospital to the one agreed upon, which made the surrogacy agreement void. The couple was scared, she said, that Pattharamon would change her mind about the second child, and they'd have to leave Thailand with no children at all.
According to the report, the friend noted that the backdrop to the surrogacy row was a military coup in the country and "it was very difficult to get around."
The takeover took place in the early hours of May 22, 2014 when Commander of the Royal Thai Army General Prayuth Chan-chua announced in a national broadcast he was now in charge.
"This has been absolutely devastating for them, they are on the edge," the friend added, referring to the days of media scrutiny and debate over their decision, months after they returned home.
Pattharamon claimed the couple asked her to terminate the Down Syndrome child when she was seven months pregnant.
Not true, the couple's friend said.
After the babies' birth, Pattharamon claimed they bought nappies and milk for the baby girl, but "didn't even look at the boy."
Also a lie, the friend added.
Whatever the details of who said what, the case has attracted attention to a largely unregulated industry subject to a confusing tangle of laws and loopholes.
Surrogate 'is legal parent'
In the state of Western Australia, where the couple is from, it's legal to seek surrogacy abroad.
There are no checks for criminal history, and no counseling is required for couples seeking offshore surrogacy, said Jenni Millbank, an expert in Australian surrogacy law from Macquarie University in Sydney.
"If surrogacy were taken onshore there would be counseling protocols prior to conception, as well as a welfare report after birth required before legal parentage is transferred; but these are not steps that occur with offshore surrogacy," said Millbank.
She said the surrogate mother is the legal parent regardless of whose egg was used. The rights of the genetic father are also "uncertain" as "different judges have taken varied approaches," she said.
Australian authorities are looking into the case, as are Thai authorities, who had already announced a crackdown on the industry amid claims rules were being flouted.
Pattharamon said she agreed to be paid 300,000 baht ($9,300) for carrying the couple's babies, money she needed to help care for her own two children, aged six and three. After she voiced concerns about how she was going to pay for Gammy's care, funds started flowing to an online campaign, which to date has raised more than $237,000 (US$220,000).
Could baby girl be returned?
Pattharamon said she's prepared to take the baby girl back if the Australian couple is are "not ready" to take care of her.
She said she doesn't intend to pursue legal action against the parents, though Millbank says she could apply to the Family Court of Australia to have the child returned.
"The Family Court of Australia has jurisdiction over anyone who has an interest in the care, welfare and a development of a child so (the intending parents) could still make their case and argue for the baby to live with them," Millbank said.
"The court would examine the competitive proposals of the parties, probably appoint an independent children's lawyer and do a welfare assessment of the child's needs and then make a decision."
The Australian courts have only ever heard one case involving a child born via surrogacy, Millbank said.
It involved a child called "Evelyn" whose birth was the result of an agreement between friends that went wrong.
"That was in the 1980s and they ended up removing the child from the family that had been raising her and taking her to the other family," Millbank said.
"It was an altruistic arrangement where the birth mother changed her mind about seven months later. And she ultimately won. She got the child back."
