@mottun73 I'll find out about the traffic order, in the meantime here's a representation for you to send:
Dear London Borough of Newham,
The alleged contravention did not occur, this is because the overall signage did not comply with regulation 18(1) of The Local Authorities' Traffic Orders (Procedure) (England and Wales) Regulations 1996. There is a "DISABLED" legend on the road surface and this clearly indicates that the bay is for disabled badge holders, the regulations do not require any additional signs. I relied on the legend and displayed my blue badge correctly.
There was also a shared use bay sign on the boundary between the bay I was parked in and the next bay, that sign had no directional signs and having seen the disabled legend, I had no reason to look for any other signs.
If the bay is a permit bay, the appropriate legend would be "PERMIT HOLDERS", this would prompt road users to look at the upright sign to determine what type of permit is required.
To put the council's case at its highest, the best that can be said is that the signage was ambiguous; in these circumstances no contravention occurred.
Yours faithfully,
Send this online and take a screenshot of the confirmation page.
