Islington - 12 parked in resident bay without valid permit

I received a PCN at 15:58, during which I was in the process of purchasing my session on RingGo which eventually went through at 16:04, which is 6 minutes after I got the PCN.

Is there an argument here to appeal based on de minimis? Would appreciate any other advice, I just feel this is very excessive.

Some context, I am a resident of a property on the street I received a PCN, but I haven’t got a permit  as my vehicle predominantly stays at my mothers address.

Hopefully no issues with the link

So where with you when you took out the session?

We see all too often people leaving the car. Then we see adjudicators wondering if people spotted a CEO and hastily bought a session...

CEO obs started at 15.54, so let's assume that you didn't see and ignore them, which places you there and parked prior to 15.54.

You bought parking rights at least 10 minutes after you parked and not in the vicinity of the car...is what their facts show. Forget de minimis

How would you intend to counter this?

DNC'ed.
