"There are still many other Engelines out there suffering abuse by their [adoptive] parents after they are separated from their biological parents," she told The Jakarta Post over the phone on Monday.
She was referring to the case of Engeline, an 8-year old Bali girl whose body was found buried in the backyard of the house of her adoptive mother, Margriet Megawe in Denpasar, Bali, on June 10, 2015.
Engeline had reportedly been adopted solely on the basis of a notary deed by Margriet.
Erlinda declined to say whether the adoption process itself could directly lead to abuse, but she said there was the potential.
"The Social Affairs Ministry has provided good regulations on adoption but some people just don't follow the procedure in their adoption process, whether out of lack of information or ignorance. [...] How do we monitor such adoptions?" she said.
The child adoption procedures are regulated in Government Regulation No 54/2007 and the 2002 Child Protection Law.
