This is a persuasive case in that it was heard by a Circuit Judge on appeal from the County Court. If you have a "No Stopping" parking charge, you are best to check this to show in what way your case is different.
Mr C often visited Liverpool Business Park to pick up off his son after work there (para 9). As such he would have been familiar with the signs there which said.
£100 charge if you stop
Mr C was only stopped for 30 seconds but this was sufficient time for Vehicle Control Services passing ANPR vehicle to capture the event. Though there were a number of arguments about the size of the signs; their number; their placement; and the meaning of "parking" or "stopping", the judge referred to the ratio in ParkingEye v Beavis when he said at para 29:
The distinction between stopping and parking was not material, if it was considered that the Claimant had a legitimate interest in preventing obstruction on the narrow access roads of this private business park when heavy goods vehicles, buses and other vehicles needed to proceed unimpeded, by imposing a charge to be paid in such circumstances.
So unless your circumstances are different, or this case is re-examined in the future, it will be a powerful argument for the parking companies wishing to enforce "No Stopping" rules .... but as the Beavis case illustrates time and time again, it all comes down to the legitimate interest of the land owner.
