If you were delivering goods to a property then this could be covered by Jopson v Homeguard.
Maybe, but they weren't loading/unloading at that moment in time, but waiting in queue to enter this site. The vehicles were parked on the pavement or with wheels on the pavement, as all the other vehicles do when queueing there. I can only guess it is to allow space for other articulated lorries to turn in and out of the sites on the road.
I emailed the customers site and they told me the road is owned and operated by GLA, and that they themselves, and other hauliers have been having the same issues, they said the fine is given if wheels are on the pavement and "obstructing pedestrian access", and this isn't mentioned on any Notice to Keeper. They, advised we wouldn't get one if no wheels are on the pavement and the vehicle is fully on the road and to inform our drivers of this.
Now, if this was a public road in a town centre or residential area and a Penalty Charge Notice from a council, then no problem I'd just have them paid. But it's a private rundown dead-end industrial estate road that leads to more industrial sites, there is no one walking along there, and many vehicles stop on there to wait to enter different sites, it seems to be common practice (whether right or not).
As they did not issue the notice under POFA 2012, and explicity stated that in their appeal rejections, how can they possibly hope to win at POPLA? I can't tell if they are actually genuinely stupid or they just do it to cause a nuisance in hopes that we just pay instead of appealing to POPLA
