I emailed PALS highlighting that. as the Landowner, the Trust had the power to cancel the ticket at their discretion and I got this reply. I know Gemini will reject any appeal but do I just follow the process?
The Parking Services have informed, the process is you initially must make the appeal with Gemini and await their response, have you made this appeal?
If you have and are unhappy with their outcome decision than you can raise this with the Trust.
