Thornton v Shoe Lane Parking: why late-notified charges are unenforceable

From the AppealAirportPCN team • LAST UPDATED: OCTOBER 2026

Thornton v Shoe Lane Parking is a 1971 court case about when parking terms become part of a contract. It may be relevant if a charge or important term was not shown until after a driver entered a parking area.

What happened in the case?

Mr Thornton drove into a car park and took a ticket from a machine at the entrance. The ticket referred to terms that tried to limit the car park owner's responsibility for injuries.

The Court of Appeal decided that the contract had already been made when Mr Thornton took the ticket. The terms shown on or with the ticket came too late to become part of the contract.

The main idea

Important terms need to be brought to someone's attention before a contract is made. A particularly unusual or onerous term may need to be made especially clear.

Why it may matter at an airport

At a drop-off zone, a driver may enter the area before seeing a clear sign explaining the charge. If the price or terms were not visible before the driver entered, they may argue that they were not shown in time.

In plain English: If a driver could not see the charge before entering the zone, they may argue that the term was shown too late. Whether that argument applies depends on the signs, the route and the facts of the case.

How this links to signage

The case and the BPA signage rules both concern whether the driver was shown the terms clearly and in time. Describe what you saw and where the signs were. Our airport appeal templates include a point about terms that were not clearly shown before entry.
