A lesbian couple had brought the case in a court to see their names registered on the birth certificate of their children and to be thus legally recognized as their parent.
Because of the old law that protect the children, the second mom was not recognized.
The Supreme Court of Brisbane wrote that their children were conceived through artificial insemination before the Surrogacy Act 2010 is commenced.
Add to that the fact that the sperm donor, who is not supposed to have contact with the children, did not want to see his name removed.
"The register will now accurately reflect the correct parents for the children and the true nature of the relationship between (the couple)," she said in her written judgment.
