All motorists fined for entering six box junctions across Ealing from late June have been promised their money back.
Ealing Council announced the dramatic u-turn after the Gazette forwarded documentation obtained through the Freedom Of Information (FOI) Act.
Drivers had been fined months after the junctions were declared illegal.
Jim Douglas, who specialises in helping people penalised for motoring offences, obtained the FOI material.earlier this year between the Department for Transport and Ealing Council.
In an email dated June 20, Ealing was told by John Munns, traffic signs policy officer at the DfT, that it would not authorise full yellow boxes at T-junctions.
The email goes on to say that any local authority with any full box it feels it cannot justify should convert it into a half box, or even remove it entirely and replace it with a 'Keep Clear' sign.
Mr Munn then writes: "We therefore...decline to authorise; Avenue Road/Uxbridge Road; Lower Boston Road/Uxbridge Road; South Road/Hamilton Road; South Road/Cambridge Road; South Road/St Joseph's Drive; Broadway/The Mall."
It wasn't until late October that the council announced it was scrapping six box junctions in the borough following guidance from the DfT.
Ealing had said anyone who paid a penalty charge notice since the DfT's revised guidance was issued on October 30 will be refunded.
But this week Phil Taylor, cabinet memfor customer and comunity services at Ealing said: "On behalf of the council I would like to say sorry and offer our unreserved apologies.
"We will be refunding everyone ticketed at the affected yellow box junctions since June 20.
"The decision was made after an email sent by the DfT on June 20, was brought to my attention.
"At the beginning of November we immediately suspended the junctions following advice from the Department for Transport.
"I believed that this was the first time the council had been given this advice or the decision to stop enforcing them would have been taken in June.
"I am furious that this email was never brought to my attention and I have ordered an immediate investigation on how this could have happened.
"The council is putting in place arrangements to refund the money."
