She wanted a human being and she got one. Now explain $150k in damages.
That's the problem with her lawsuit.
If she was told that the sperm donor was white and they then used the wrong sperm then she probably has a cause of action for breach of contract, but she cannot prove any damages. The cost of raising this child will be no greater than raising a white child. She is entitled to get her money back and nothing more.
Either way, the child is probably going to need years of intensive therapy, but that is entirely because of the moms.
Oh I agree with just paying her the money back and that is it. Mental anguish and all that stuff which are not tangible are the bane of medical lawsuits.
