Halifax town centre parking fines refund may cost £500,000
Reimbursing people who were illegally fined for parking in a West Yorkshire town centre may cost Calderdale Council £500,000.
Up to 7,000 people will be able to claim a refund after a traffic regulation order for Halifax was found to be invalid.
The error means the council cannot fine people who failed to pay on-street parking charges after 2008.
Council leader Stephen Baines said the mistake was "going to be expensive".
Drivers issued with a fine can apply for a refund online, the council said.
The traffic order relates to charges for on-street parking spaces and to a parking scheme in Skircoat, which includes on-street parking bays and parts of the residents' permit scheme.
The authority said it had stopped issuing penalty charge notices and was switching off parking meters in the areas.
Mr Baines said: "We estimate the cost is going to be somewhere between £200,000 and possibly £500,000.
"It was a mistake by somebody who worked for the council in 2008. That person is no longer employed by the council."
He said the council was reviewing all traffic regulation orders across Calderdale to ensure they were correct.
