Laurel Hubbard
The IOC, after listening to the evidence, has set the criteria by which it is fair for transwomen to complete in competitions. And by fair I mean, transwomen do not have an advantage over natal women. Other sporting organisations tend to follow the IOCs lead. As Laurel Hubbard has followed the rules, then she should be allowed to compete.
If Helen wishes to argue this is unfair, then she needs to present evidence which is more compelling than the evidence the IOC viewed.
Ian Huntley
If Ian Huntley sincerely and genuinely identifies as a women, completes a process to reassign his gender and can be safely managed in the women's estate, then he should be transferred. However, I don't think anyone believes he is sincere. Still if he is transferred, maybe he would get to share a cell with Rosemary West.
Tara Wolf
Here the district judge, following the court rules, requested that Tara be referred to by her preferred pronoun of she. He and she - don't have a specific legal meaning - so it is just a matter of courtesy.
