From the photos your car is causing an obstruction of the pavement. However obstruction is not alleged on the PCN.
The contravention alleged is
"Parked with one or more wheels on or over a footpath or any part of the road other than a carriageway."So the question is are any of your car's wheels on or over the pavement/footpath? There appears to be a concrete strip in between your paving bricks and the paving slabs of the footway presumably marking the edge of the footway. And your rear wheels look like they might be just touching the concrete strip. It's hard to say whether or not they are touching, the rear tyres might be fully on the bricks. It's very subjective
As you are within the 14 day discount window I would submit an informal representation to the effect that no contravention occurred as none of your wheels were on or over the footpath. As evidence by the Civil Enforcement Officer's evidence photos, all wheels are fully on the bricks of your driveway. The Council will normally re-offer the discount if an informal representation is received before the 14 days elapse. You might as well have a go.
Also ask them which of your wheels were on the pavement?
The CEO's handbook says that they should record how many wheels are in contravention. And it's not on the PCN.
I imagine they will reject and that ultimately you will need to appeal to the Independent Adjudicator at the London Tribunals. Lose there and it would be the whole penalty of £130 to be paid. Win and it would be £0.
I suggest that you should pursue the matter to the adjudicator if you want to keep parking in the same spot and can't get the car further forward. Be aware that even if you win the adjudication is not binding on any other adjudicator. But it helps were it to happen again.
