"Any offence of that nature is serious since it represents the intention of the offender to manipulate our justice system and to produce injustice. As such, the courts have traditionally treated such offences with condign punishment. However, in your case the manner of your offending is, if not unique, almost so, for you devised a plan which manipulated the process of the investigation of one of the most horrific series of murders ever seen in this country.... .... I am satisfied that one of the factors which may well have contributed to his [Sutcliffe's] remaining at large for so long was your behaviour."
"What I find to be significant is that having apparently failed to get a reaction from the first two letters [in 1978] you did not send any more until after that report eleven months later in the Sunday Mirror, and of which I am satisfied that you either read or you were aware of within the month you wrote the third letter. I consider that was because you now realised that your earlier letters were not being entirely ignored and you were causing some police reaction and you wanted that reaction to continue. 18. still at work. The potential consequences of misdirecting the investigation were made more obvious with each killing. Yet, even following that killing, you went on to send the sinister tape. .... It cannot be said that your actions caused or even directly led to the deaths of the women who were murdered after your communications or that the killer would have been caught earlier, but when Peter William Sutcliffe, the true killer, was arrested, he was to comment to the police that their misdirection towards a Geordie killer had given him confidence because he did not have a Geordie accent. The least that can be said is that those victims would have stood a better chance of not being attacked had the police resources been directed within West Yorkshire. Indeed, it is likely that Sutcliffe, who had come to the attention of the police and been interviewed, may have been placed much higher in the list of suspects had the police not been searching for a man with a Geordie accent.... This behaviour in my judgment places your actions at the very top of offences of perverting the course of justice. It is almost impossible to envisage more serious acts of this nature."
