The situations where it is legal are very, very few and rare. In this situation there is no reason a judge would allow any medical records to be subpoenaed, especially when alternatives that don't delve into medical records are available. Literally, HIPPA is so strict that police can't even flaunt their badge as above it and do as they please. If you want to tell the police no, go into the medical field because there is a chance it could happen and you'd be legally in the right for doing so.
No one--trans or cis, hetero or homo, white or black--no one is entitled to the medical information of another. And any proposals that expect it are illegal and unethical.
Nobody has suggested...especially I have not suggested...that the shelter (this is about a women's shelter, yes?) has the right to get medical information without the permission of the applicant.
this is about an applicant who wants a service/product...in this case, shelter.
It is perfectly legal AND ethical for that shelter to require certain medical information from the applicant if that information is pertinent to the situation, that is, whether someone who is physically a man is actually a 'woman in a man's body.' True, the shelter cannot go around the applicant and HIPPA laws to get that information, but it CAN say....you give me the information or we don't provide the service..
And that is absolutely legal and ethical. If you don't think so, then YOU go sue insurance companies and the motor vehicle departments of whatever state/nation you want to drive in. You are, in fact, arguing a strawman here, since I am certainly not advocating that a shelter get information not voluntarily provided by the applicant.
What I AM saying is that a shelter, like any other service provider, can legally and ethically ask an applicant for pertinent medical information before providing that service, and, though it cannot force such disclosure, can certainly refuse to provide the service if the information isn't provided.
You know...the way my sons have to pass medical exams (including drug tests) before they can work for a trucking company, or I had to prove that I was free of TB before I could teach school, or..????
So dial it back, Shadow Wolf. It's simple. If I were running a woman's shelter, and a man with all his physical accouterments showed up claiming to be 'really a woman,' I would require him to support that before I allowed him in. If he could not, or was not willing to do so, I would refer him to a different shelter; perhaps the 'co-ed' one that takes women AND men down the block. I wouldn't sue, I wouldn't go to court, I wouldn't send the police. I would just....not let him in.
As would be my right. No HIPPA laws violated. He doesn't have to provide the information, I don't have to let him in.
................and I wouldn't allow the wolf who claimed he really was a sheep in my flock, either. Not unless he could 'baaa' and provide me some wool...or at least some hint that he would if he could.
