I don't often side against you, AOG, but you’re a bit of the mark with this one.
With a few exceptions (which do not concern us here) the only statutory stipulations regarding most criminal offences are the maximum sentences that can be handed down. All the rest is “guidance”. As far as the Sentencing Council’s (SC) guidelines go, judges and magistrates must sentence in accordance with them unless there are reasons (which must be announced in open court at the time of sentencing) to depart from them. Included among the guidance for most offences are (non-exhaustive) lists of aggravating and mitigating factors relating to both the offence and the offender. In this instance revised guidance for knife crime is proposed which will suggest more lenient sentences be imposed on offenders who have (what is euphemistically called) a “troubled” background. The law is not being changed or defied. Only revised guidelines are proposed and guideline revisions are published constantly.
Further, The Mail’s article contends that the SC is “dominated by judges”. This is not correct. The current membership of the Council is as follows:
Rt Hon. Lord Thomas, Lord Chief Justice, (president of the Council) – Judge
Rt Hon Lord Justice Tracey (Chairman of the Council) – Judge
Simon Byrne (former police Chief Constable) – Non-Judge
Mark Castle (Chief Executive of Victim Support) – Non Judge
Rosina Cottage, QC (Barrister) – Non-Judge
HH Judge Julian Goose, QC (Recorder, Sheffield) – Judge
Martin Graham (Probation Chiefs’ Association) – Non-Judge
Jill Gramman, JP (Magistrate) – Non-Judge
Rt Hon Lady Justice Hallett (Crown Court Recorder) – Judge
HH Judge Sarah Monroe, QC (Recorder, Portsmouth) – Judge
Professor Julian Roberts (Professor of Criminology at Oxford) – Non-Judge
Alison Saunders (director of Public Prosecutions) – Non-Judge
Hon. Mrs Justice Thirlwall (Midlands Circuit Judge) – Judge
District Judge Richard Williams (District Judge South Wales Magistrates’ Courts) – Judge
So, 50:50 judges (if you include DJ Williams, who does not wear a wig and gown and sits only in Magistrates’ Courts). You would expect something like the Sentencing Council to be composed of a number of members from the judiciary, but the current council is hardly “dominated by judges”.
Yes mamy, the Sentencing Council was formed in 2010. Its replaced the "Sentencing Guidelines Council" which had existed for many years previously. Not much changed in 2010 apart from the name.
