I've drafted the following appeal. I've kept it simple and concise.
Dear Hammersmith and Fulham Council,
I am writing to formally challenge the Penalty Charge Notice (PCN) issued for an alleged U-turn.
A High Court judgment has made it clear that for a U-turn to occur, the vehicle must, after the manoeuvre, travel in the direction from whence it came.
In this case, my vehicle did not travel back in the direction from which it initially came. Therefore, no U-turn took place, and no contravention occurred.
On this basis, I respectfully request that the PCN be cancelled.
Thank you for your consideration.
Kind regards,
