"First, conduct which tends and is intended to pervert the course of public justice strikes at the heart of the administration of justice and almost invariably calls for a custodial sentence. Deterrence is an important aim of sentencing in such cases … Secondly, the appropriate sentence of course depends on particular circumstances of the specific case. The circumstances vary across a very wide range. Therefore, only limited assistance can be derived from considering previous decisions in other cases. Thirdly, in assessing the seriousness of a particular offence, relevant factors including the seriousness of the underlying offence, the nature of the deceptive conduct, the period of time over which it would continue, whether it casts suspicion upon or led to the arrest of an innocent person, and the success or otherwise in the attempt to pervert the course of justice. In addition, of course, the offender's previous character and any personal mitigation must be taken into account." 12. "
"In my judgment, Carmen Anghel was in an acutely difficult position. She was not so overborne that she ever could say she was acting under duress; however, she was easily exploited. She was without her own resources. She had in one sense little choice. She is a single mother of a teenage boy whose father is a convicted murderer serving life, and who he has never seen other than in prison. She is working. She has no previous convictions. She was in her 20s when she became involved in the conspiracy."
