A transsexual whose 17-year marriage to an heiress was nullified when the wife discovered her husband was a woman is not legally a "parent" of her 14-year-old daughter born from donor sperm, the Court of Appeal ruled today.

Interesting legal issue here. Both parents raised the child for 14 years, but the father is not considered a parent because of his sex at the time? I wonder about the implications of that...
