A lesbian couple wanted a baby, so one of them got pregnant with the help of a sperm donor. The baby was born. Then the lesbians split up. Then the sperm donor got sued for child support. And then, in a surreal conclusion to the whole disaster, the Pennsylvania Superior Court declared that all three adults are the child's legal parents, with all the rights that married parents have who make kids the usual way. Elizabeth Marquardt has a very calm op-ed in the New York Times about the legal earthquake that this decision makes.
What impresses me most about this case is not so much that this poor kid has three parents, as that he barely has one.
