There are two clear dropped kerbs opposite each other, so I think you will struggle to overturn this PCN, other than on the grounds of "legitimate expectation". This has won in the past where a PCN recipient has parked for a long time in a state of contravention, but received no PCNs. HOwever, it is up to you to prove this.
The other aspect which could win, is errors of content in the PCN, and these are often found in the "small print". We rarely see PCNs from East Suffolk, indeed yours may be the first ! There is what I would call a fatal error in the text relating to submitting representations.
This is what the The Civil Enforcement of Road Traffic Contraventions (Representations and Appeals) (England) Regulations 2022 say about content of a Regulation 9 PCN (yours)
CHAPTER 1
Information to be included in regulation 9 penalty charge notices and enforcement notices
Information about right to make representations or appeal to be included in regulation 9 penalty charge notices and enforcement notices
3.—(1) A regulation 9 penalty charge notice must include the following information—
(a)that a person on whom a notice to owner is served may, in accordance with these Regulations, make representations to the enforcement authority against the penalty charge and, if those representations are rejected, appeal to an adjudicator;
(b)that if, before a notice to owner is served, representations against the penalty charge are received at such address as may be specified in the notice for the purpose those representations will be considered by the enforcement authority;
(c)that if a notice to owner is served despite the representations mentioned in sub-paragraph (b), representations against the penalty charge must be made to the enforcement authority in the form and manner and at the time specified in the notice to owner.
The information requirement in (c), is not conveyed in your PCN. This clause is there to make sure that a PCN recipient who has submitted representation against a PCN, is informed that if a Notice to Owner arrives, he must submit representations again, against the Notice to Owner. The PCN doesn't make this clear.
