My pensioner partner has recently been issued with a PCN by Civil Enforcement Ltd. by post, for failing to display her Blue Badge whilst parking in a disabled bay on a Tesco car park in Leigh Lancs. No indication of this incident was given at the time. She was a passenger in her own car. She was there for approximately 20 minutes and the carpark was fairly empty. She had a stroke three years ago and is a little forgetful at times.

Civil Enforcement Ltd. have demanded £150 reduced to £75 if she pays within 28 days. This seems a huge amount for so small an incident. She has appealed to them explaining the circumstances, and supplying a copy of the badge, but they just aren't interested. Is the above legally enforceable? The company has threatened legal proceedings through the County Court if she doesn't pay up.
