According to the much missed campion it might not even matter if the contract was not signed :
"Cheque Book Journalism, Press Council Report 1981. News Corp/ News Group/ News International are in breach of Declaration of Principle regarding speaking to Julie Mugford. It states that this is the case even if a Journalist offers a bid on a hand written note. Did the NotW approach a third party who would not be a witness, some like Julie Mugfords Mother. The 1981 report clearly states that payments should not be offered by Newspapers/Media Groups to the Relatives or Associates of persons Accused of Crime, I take this then must include Police. The Price of the Story on the day the trial ends to its value some months later would be £1,000,000 Sunday after trial £100,000 three months later. Julie Mugfords testimony is worthless, what you have found proves this, this should be highlighted by Simon McKay at Leveson this week.
