The letter doesn't actually say why they decided to cancel and is 'without prejudice' to their position, what position, of being incompetent? 'Without prejudice' means the letter cannot be produced in Court but PCNs don't go to Court so what is the point of including such nonsense?
Mr Mustard showed the letter to his Solicitor to see what he made of it and his opinion was:
'One and a half pages of hot air. Why not just say we have decided to cancel it.'
Not very often you get a free legal opinion.
