As the law stands and is interpreted by parking enforcement outfits they think they have the right to do this. However, a reader has argued that because their ticket machine took your money for parking, there is a contract between you and the parking enforcement company for them to provide you with your hour's parking whether you miskeyed your registration or not. Such a case needs to go to a County Court, then a High Court and then to the Supreme Court to get a ruling on these particular facts that could be construed as deliberate entrapment and exploitation.
