I drove to Buchanan Galleries car park in Glasgow. The final approach is along a one-way street that at the car park entry becomes a bus lane.
The car park was closed and the entry blocked with scaffolding. I had to drive through the bus lane to escape.
Glasgow City Council sent me a fine, I disputed it but they didn’t want to know. I’d seen no signage warning of a closed carpark, so submitted a FOI request regarding alteration to signage on the approach. They were only able to supply details of PROPOSED signage, and were unable to show evidence that the proposed signs were ever put in place.
I appealed to the Adjudicator and they had had “scores” of identical appeals and they rules against GCC. I was refunded the fine that I had paid.
If you can prove it was unreasonable, it is worth pursuing.
