A women in British Columbia is suing under the Canadian Charter of Rights and Freedoms that she has a right to know who her sperm-donor father is. She claims she is entitled to valuable health information, since all she has been told is that her father was a healthy medical student with type A blood. I can see that other physical health information, such as a family history of heart attack, cancer, or genetic disease, should also be passed on to her, if it had been collected in the first place.
The BC woman is also claiming that she suffers from psychological distress from not knowing who her father is. I agree that this is a real problem. Elizabeth Marquardt is studying this very subject, and I look forward to the publication of her research.
Nonetheless, when the donation was made and accepted, the rule was that that was the end of it. You can debate whether that should be the rule in the future, or whether sperm donor or mother should have accepted those terms. But they did. So to this questing woman I say "No." You can try to change the rules for other people in the future. But there is a larger principle of being able to trust the rule of law that trumps even your psychological distress.
In sperm-donor court, I would be a hanging judge.
