Investigating Rape

Sexual offences conviction rate plummets according to new data

Campaigners have expressed alarm over new statistics produced by the Ministry of Justice which show a dramatic drop in the conviction rate for sexual offences in the past year, from 61% in 2012 to just 55% in 2013.

These latest figures follow the Bureau’s revelation earlier this month that the actual number of successful convictions of rape dropped last year. The Bureau’s investigation into the prosecution of rape found that despite an increase in offences the number of rape cases taken to court has also dropped dramatically.

Keir Starmer, who was in charge of the CPS until November 2013 told the Bureau: ‘We initially thought that the numbers might be plateauing and would continue the upward trend.’

‘But then they started to go down.

‘And it is not due to rape offences dropping, I am certain about that.’

The new figures from the MOJ are for sexual offences as a whole – not just rape. The huge drop in the conviction rate adds further to the sense that something is going wrong.

In response to the figures Yvette Cooper, the shadow home secretary, said: ‘It is alarming that convictions for sex offences are falling at a time when the number of recorded offences is rising sharply.

‘We have warned David Cameron and Theresa May for some time that there is a growing justice gap and more serious criminals are getting away with the their crimes without facing prosecution or the courts – let alone conviction.

‘Overall, convictions have fallen for sexual offences, domestic violence cases and child abuse cases since 2010.

‘It’s time the Home Secretary took action to make sure victims get the justice they deserve.’

The latest figures from the MOJ break down the different types of conviction and show that the actual numbers of those convicted for many categories of rape have decreased. For example ‘rape of a female aged 16 or over’ has decreased by 3% between 2012 and 2013, and under 16 decreased by 4.5%. Convictions for rape of a male under 16 also decreased by 3%. Convictions for rape of a male over 16  is one of the categories that has gone up – by 11%.

The MoJ’s statistics also show that prosecutions of sexual offences have the lowest conviction rate of all offence types. Drug offences had a successful conviction rate of 90% in 2013 for example.

Conviction by offence


Other work by the Bureau has revealed dramatic cuts to CPS staff numbers after the organisation’s budget was cut by 27%. FOIs to the CPS showed that its legal team had been reduced by 31% since 2010. Higher court advocate numbers were slashed by 44%, and the number of barristers reduced by 27% since 2010.

The Bureau’s work on rape prosecutions has shown that the attrition rate – the number of cases that drop out before conviction – is so high that a former senior adviser to the Metropolitan Police Service, Professor Betsy Stanko told the Bureau that for many rape victims the crime has effectively been decriminalised.

Analysis of figures produced through Freedom of Information requests revealed that up to a third of all rape allegations made to police in some parts of London were never recorded as crimes at all in 2013.

In one shocking case reported to the Bureau a woman was told her rape allegation would not be taken up by the CPS in part because she had been wearing Spanx underwear at the time.

A CPS spokesperson said: ‘The effective prosecution of rape continues to be a key priority for the CPS. The CPS and ACPO have been working together for many months to investigate the reasons behind the drop in the number of rape cases referred by police to CPS, as identified in the last CPS report on Violence Against in Women and Girls published July 2013.

‘As part of this longstanding piece of work, a meeting was held between police and prosecutors in September and a joint national rape scrutiny panel was convened in April to analyse the drop in referrals.

‘A joint CPS/police action plan resulting from this ongoing work on referral rates, but looking at all aspects of prosecuting rape cases from investigations to prosecutions and trials, will be published shortly. It will set out a number of actions for police and prosecutors to improve the way these cases are handled. The specific actions will be announced in due course.’
