Contravention code 90 is a parking contravention, enforced by civil enforcement officers. If you have received this PCN from Tower Hamlets, Parking Mate AI can check it for defects and prepare a challenge letter for London Tribunals.

Contravention code 90 means: Re-parked in the same car park within one hour after leaving. This is a parking contravention issued under the Civil Enforcement of Road Traffic Contraventions (General Provisions) Regulations 2022. Tower Hamlets enforces this via civil enforcement officers on the street.
You have received a penalty charge notice from Tower Hamlets with contravention code 90. In plain English, this means the council considers that you re-parked in the same car park within one hour after leaving.
The legal basis for this PCN is the parking enforcement scheme, backed by a traffic regulation order (TRO or TMO) that Tower Hamlets must have properly made and signed. Without a valid order and compliant signage, the restriction is not enforceable.
To challenge this PCN, you can make formal representations to Tower Hamlets. If the council rejects your representations, you have the right to appeal to London Tribunals. The adjudicator's decision is independent and binding on the council.
