I'll admit I didn't study the antecedents of the regulations in great detail but, subject to being corrected by someone more knowledgeable, the mechanism of enforcement as if the charge were payable under a County Court Order goes back to London's decriminalisation of parking in the nineties.

I'd say that is a genuine DWP letter. Looks like sort of thing they send out where a benefit overpayment has occurred; have you been on Universal Credit or Tax Credits? As above ring them up and ask what it's about. If you don't feel confident to do that yourself then your local Citizens Advice will probably be able to help.

The Charge Certificate is enforceable as if it were payable under a county court order http://www.legislation.gov.uk/uksi/2012/1234/regulation/4/made The county court at Northampton, wearing its other hat as Traffic Enforcement Centre makes an order for recovery but it seems you are right in that (oddly in my view) that order seems not to qualify for registration as a debt.

Epabak Jotona first of all, for clarity, OP is shorthand for Original (or Opening) Post(er); the person starting the thread. In this case yourself. As I've already posted elsewhere a parking ticket issued by a Council in England and Wales (or by Transport for London) is a Civil Penalty. It's not a crime and, excepting that unpaid penalties end up at the Traffic Enforcement Centre (Northampton County Court), they go nowhere near the court system. The only people who know about this are the issuing Council, your wife and yourself. Provided you pay it that tremains the case. The risk you take, as Michael Browne points out, is that while you're on a wild goose chase to get the PCN amended the Council, as they do, plough on and take it to enforcement. At that point it becomes enforceable as a County Court Judgement and you have bailiffs after you, or rather your wife and it can end up on the Register of County Court Judgements at which point it WILL show up on a search.

If you're confident you are correct take it to the Traffic Penalty Tribunal. The worst that can happen is you lose and have to pat £50. The success rate for those who attend the hearing with a well prepared case is pretty high. It was a bit of a busman's holiday for me as I previously worked in an Quango that had some oversight of Tribunals including those concerned with parking.

Man in Middle will be along soon but surely ACPO stuff is guidance and has no force in law? Why, if he sees your car coming towards him at what he estimates to be at or in excess of limit, can you be confident that camera officer had no Prior Opinion?

I'd suggest appealing it based on the poor markings. I got a parking ticket in Camden in Autumn 2018. Residents Bay which was not sufficiently differentiated from adjoining Pay and Display bays. Got my photographs together and a clear statement of my arguments. Stick tio the facts however bone headed the Council appear to be. The Adjudicators have a library of significant cases on their website, see if there are cases similar to use. If there are it will help you see how thw adjudicators approach the issue of parking outwith bays that are ill-marked. These cases are not a binding precedent but can be persuasive. I was lucky in that there was one at exactly the same location and pretty much identical facts 20 years previously.

The limit for cars is 70 on dual carriageway but is lower for some other vehicles such as vans. What make/model of vehicle were you driving at time you were 'flashed'.
