N/A
Relevant Sentencing Case Law

R v Ford [2006] 1 Cr.App.R.(S.) 36

• It is appropriate to fix the sentence for attempted murder at a level such that the offender would in fact serve about half the minimum term that would have been set for the complete offence.
• Where enactment of the Criminal Justice Act 2003 would lead to a higher minimum term for murder, there should be a corresponding increase for attempted murder.
• Because provocation and diminished responsibility are not available as defences to attempted murder, comparison with manslaughter sentences would be more appropriate in cases where such defences would have succeeded had the charge been murder.
