I will PM you a link to put in the representation, we can use the click count to confirm whether they've looked at it or not (obviously do not click on that link yourself as we want the click count to remain at zero). If they don't click on it, we can then prove they've failed to consider all of the evidence. If they say in the rejection that they've considered all the evidence, we've got them for lying as well.
Dear Chelmsford City Council,
I would ask you to exercise discretion on this occasion for a first-time contravention. On the date in question I was accompanying my father to see partner and then we were all going to go out to a cafe, my father is elderly and has a blue badge which unfortunately I forgot to display. A copy of the blue badge is available at LINK
I hope you will be able to exercise discretion to cancel on this occasion and thank you for your consideration.
Yours faithfully,
Make the representation online via the council website and take a screenshot of the confirmation page.
