Wirral Council said it regrets a "failure" over a planning decision in connection with CCTV cameras at a car park.
The mistake was made by council officers who approved adverts linked to controversial CCTV cameras that have wrongly fined at least 2,000 people at the Cherry Tree Shopping centre car park in Liscard.
The cameras, operated by Smart Parking, have been accused of "preying on people's misery" and remain incredibly controversial. Smart Parking had applied for planning permission to keep the cameras but this was rejected by councillors in October.
