Car parking fine advice (Autism)?

"It seems that there was inadequate signage "

That's going to be key. He will have to prove that the sign wasn't clearly visible.

"and an unfair sum "

That's debatable, as the fine is the same for everybody.

"and it did not stay over night."

That depends on the carpark's definition of "overnight" if their regular hours end at 6:00 PM and his car is still there at 6:30 PM, then that could easily constitute overnight park, how long his car was actually there is inconsequential. It's like checking into a hotel and then leaving a couple hours later, you're still going to pay the full rate for the room.

"Furthermore it seems wrong that if they have your car then they refuse to let you enter it to get your belongings without signing a contract to pay £75."

Happens all the time in the U.S. I had my car towed, it was taken to an impound lot where I had to part with $140 USD before I could even see it again, let alone retrieve anything from it.

Pretty much everything is going to hang on whether or not the signs were posted properly, and unless your friend has pictures that show that it wasn't, then he's going to be out of luck.

Also, I'm curious, if your friend apparently can't work due to his condition (yet somehow passed his driving test), then how can he afford to keep a car on the road?

There is always a right to appeal but the fact that he is considered competent enough to drive a car safely on the public roads means that he should be able to read and understand road signs and of course this also applies to parking legally, the fact that he is autistic would be no excuse because the very same thing happens to drivers that do not have medical problems, he may well be successful with an appeal but I somehow doubt it, he passed a driving test and he is governed by the same laws as the rest of us, of course if the car park was closed early and he can prove it, he would be exonerated just as we all would.

If you can pay the fine do it and move on. Wait a minute your saying that you got a ticket for paring your car over night in a parking spot when in actuality you were only there 30 minutes. Got an idea you need to bring any whiteness who can tell the judge that you were someplace else that night and that the bobby or constable made a mistake. By the way more then likely he will be their. Do not being people who will lie for you because you then can end up in the you know where.

Alternative therapies can be helpful in reducing anxiety, but it may take some time before you see results. If you are having a panic attack or other severe symptoms of anxiety, alternative therapy alone will probably not be enough. Alternative therapies often work best when used along with traditional treatment like medication and counseling. It’s always best to consult your doctor before beginning an alternative treatment program, especially one that includes herbal remedies. Some of these can have serious side effects, and some can be harmful if combined with certain prescription medications.
