Why? You're saying this like it's a self-evident law of nature, when it clearly is not. Biology offers no protection whatever to a woman impregnated by a man who refuses to support her; the law does that. Are you saying he
legally and morally ought to have no more say in the matter, even when he hands them over with a specific, mutually understood and agreed set of conditions, and, but for those conditions being agreed to, he would not have handed it over?
No: the man and woman made a contract, the contract was understood by all parties, it was not unconscionable, and there was
clear evidence that the man did not want to become a father against his will, because he made that part of the contract.
It is a grave immoral injustice for the judge to set aside a contract because she felt sorry for one of the contractors.
This is a great incentive to be very careful who we allow to have some sperm.
If you mean it will have a chilling effect on charitable sperm donations, I'm sure you're right.
Everybody wants their rights and everybody has good reasons why their rights should be validated. A man wants rights, the woman wants rights. It's complicated when we try to determine whose rights take precedence.
In this case, it wasn't complicated at all. The woman had no right to the fertilised eggs without the father's permission. It couldn't be
less complicated.
Actually, it just looks complicated. The real complication is when a third person shows up and they have a whole new set of rights which supersedes the man and the woman and all their rights put together.
It really sucks, but a baby is not a library roof, so yes, "tough shit, you are not entitled to have your sperm back."
There are no babies anywhere in this scenario. There are fertilised embryos. A fertilised embryo is not a person. It is
property. In this case, it was the joint property of the man and a woman, and each needed 100% cooperation from all owners in order to do anything other than continue to store the embryos.
