Sorry, but it's not clear what you want us to do. If you want advice on whether to take them to London Tribunals or just pay-up, can you please give is a lot more information on what you did when parking in this car park. Did you for instance rush off and pay remotely from the car park ? Time has always been allowed to buy a parking ticket, and this extends to those paying using an app on their mobile, if not time was allowed, nobody could ever park legally in a pay car park. However, the time interval between parking and actually buying the parking tariff needs to be reasonable in the circumstances. We do see a lot of PCNs where the driver had left the car park before using his app.
