The Pennsylvania Supreme Court has affirmed two lower court rulings that the former same-sex partner of a child’s biological mother cannot seek custody of the child because she has no biological connection to him and has not legally adopted him.

Last year, the Superior Court in C.G. v. J.Haffirmed a Centre County judge’s determination that C.G., who had been in a relationship with the biological mother of a son born in Florida through artificial insemination, was not entitled to custody of the boy because she was not legally considered a parent. The litigants are identified in court papers by their initials only.
