Can we see your appeal and their reply pl.
The car was parked where I thought was a drop-off point,
It is, the PCN even says so. The issue is whether the conditions of use require that the vehicle is attended at all times, but we can't tell because the sign in the PCN is unreadable. Pl post a clearer sign if you have one or transcribe its contents.
I could not see the hospital limiting use of the drop-off point in this way, it's counter-intuitive. One of the reasons a car would be there in the first place is because the passenger had difficulty walking, therefore they're dropped close to the hospital entrance. Any other construction is nonsense, for example if it's just so that a person could be dropped off without the need to park, then it could be anywhere on site, it wouldn't need to be by the front door. But it is, therefore it's predicated on the passenger's perambulatory predicament.
Given this, then it may be used by impaired passengers providing they can make their own way into the hospital, but if they can't and require assistance from the driver then the car must be parked elsewhere and the more impaired passenger forced to walk further with assistance.
Try the above on PALS!
