So I've double-checked the special authorisation for the suspension sing (https://assets.dft.gov.uk/trafficauths/case-4111.pdf), and unlike many others it doesn't say the sign cannot stay after it is no longer needed.
However The Barnet (Charged-For Parking Places) Consolidation Order 2014 (https://drive.google.com/uc?id=1uNVnPD97FCOO0wPkubyicWwGHM8Yy7qM) says at article 20(1) that:
Any person duly authorised by the Council or the Commissioner of Police of the Metropolis may suspend the use of a parking place or parking area or any part thereof whenever they consider such suspension reasonably necessary:
A list of reasons for suspensions is then given. It is arguable that once the works were completed, it was no longer necessary for the bay to be suspended, however this is not as clear-cut as the Secretary of State's authorisation saying the sign cannot be there after it is no longer needed. You therefore need to decide whether you want to carry on.
After your 12th October reply I immediately posted an appeal, but in your later reply ^^^ you found my chances were not so high but it was too late!
(To recap, the PCN was paid but then they agreed - see letter in earlier post) to refund and formally consider my appeal.)
They've now replied with the following rejection, but weirdly have now moved the goalposts and said they would only refund the £65 if I win Tribunal appeal, and if I lose Tribunal then they'd charge me further £65. They don't say what happens if I do nothing, but presumably a Charge Certificate.
I'm hoping this rather strange reply means they've committed at least a procedural impropriety as it doesn't seem to comply at all with https://www.legislation.gov.uk/ukpga/1991/40/schedule/6/paragraph/4!
