OK - here's a redraft on that basis. I disagree that it's 'clear' there was sufficient space, by my reckoning there's only about 30cm in it, but agree it's clear that the footage doesn't adequately prove the council's case (i.e. show a forced stop on balance of probabilities).
Dear London Borough of Redbridge,
Re PCN XXXXXXXX
I challenge liability for this PCN on the grounds that the contravention did not occur.
Having had the opportunity to view the video footage I can see it shows that no contravention has taken place. Under the relevant regulations a contravention only takes place if a person causes a vehicle to enter the box junction so that the vehicle has [my emphasis] to stop within the box junction due to the presence of stationary vehicles. The footage shows a large space beyond the box junction which would be sufficient to accommodate my vehicle. As such my vehicle was not forced to stop where it did due to stationary vehicles and it follows that no contravention took place.
I would further add that that the penalty charge notice ('PCN') does not adequately particularise the alleged wrongdoing. The location of the alleged contravention is given as "Ilford Lane", but the name of the road junction is not given. I have looked online and I can see that Ilford Lane is over a mile long and has some 35 junctions, but I cannot find any box junction markings so it seems the box markings have been painted since the Google Street View car last drove down this road. Living many hundreds of miles away, near Blackburn, I have no reasonable opportunity to return to the location to seek out the junction.
As the notice does not allow me to understand where it is that the contravention is alleged to have taken place, the notice does not adequately specify the grounds on which you believe the penalty is payable, I refer you to the decision of adjudicator Carl Teper in Saijal Patel v London Borough of Brent (2160240742, 8 August 2016) and adjudicator Andrew Harman in Sandra Grauzyte v London Borough of Redbridge (2230201115, 31 May 2023).
For these reasons, it follows that the notice must be cancelled.
Yours faithfully,
