Lord Justice Treacy acknowledged that "perhaps we should have" been quicker to recognise that children in sex cases should always be treated as victims rather than being involved in contributing to the crime. Speaking on BBC Radio 4's Today Programme, he said:
We are sending out a very strong message that the focus is on what the offender did and what his motivation was and that the child victim should not be treated as contributing to the offence.
Tougher sentencing guidelines for sex offenders have been met with praise by children's campaigners.
The NSPCC chief executive Peter Wanless praised the removal of "ostensible consent", the idea a child over the age of 13 can consent to sex, as "a step in the right direction".
It is important sentencing reflects the severe damage caused by highly manipulative and devious sex offenders, who may use positions of trust or celebrity status to target children.
Technology is playing a part in the way offenders seek out and groom children....It is right the guidelines reflect the harm caused and the people who cause this misery feel the full weight of the law.
The outdated view children can in some way be complicit in their abuse must be stamped out. The new guidance is a step in the right direction towards addressing this terrible myth.
The Home Office has been accused of "shocking incompetence" for leaving a legal loophole that prevents police from holding the DNA profiles of thousands of suspected sex offenders.
From October, police in England and Wales will be banned from indefinitely holding genetic information on people arrested on suspicion of sexual and violent crimes once they have been released without charge.
Police will be given the right to apply for data to be held for longer, the BBC reported.
But with this appeal process not yet in place, Labour said many forces are already following government directives to delete records ahead of the change of law.
Shadow home secretary Yvette Cooper said: "Theresa May's failure to prevent and deal with this incompetence shows she has not taken seriously enough the risks to rape convictions and crime from her policy."
The Home Office said: "Forces will be able to retain DNA from someone arrested and not charged for up to three years, but only with permission from the biometrics commissioner. And all DNA samples taken by police are checked against the national database before deletion."
Splitting up offenders between the public and private sector according to risk threatens public protection.
Offenders are generally not a compliant, problem free, group of people. They disproportionately suffer from mental illness, are four times more likely than the general population to misuse drugs and are 10 times more likely to have been in care.
They need to be supervised by experienced staff who can motivate them and properly assess risk.
– National Association of Probation Officers (Napo) general secretary Harry Fletcher
More than 50 cases have been pulled together by the National Association of Probation Officers (Napo) after it approached members from across the country to provide examples of "complicated" medium risk sex offenders.
Among the offenders who would be transferred to the private sector under Justice Secretary Chris Grayling's shake-up of rehabilitation, are a 32-year-old repeat offender in Greater Manchester who was convicted for violence against a child.
The dossier includes cases of child abuse, harassment by the internet, intent to cause grievous bodily harm, unlawful wounding and instances of repeated domestic violence.
Some 2,300 sex offenders will be among the criminals whose supervision is outsourced to private contractors under government reforms to probation, it was claimed.
Around 3,200 gang members, 8,400 people convicted of domestic violence and 15,900 robbery cases are also among the "medium risk" offenders set for private supervision, the National Association of Probation Officers (Napo) said.
The public will be put at risk if such offenders are taken out of the care of the public sector and transferred to private firms such as G4S and Serco, the union said.
Speaking yesterday, Napo general secretary Harry Fletcher said: "The Government's plans are both chaotic and dangerous."
Serial sex offenders will be made to take lie detector tests on their release from jail, it has emerged. It follows a series of pilots launched by Labour in April 2009 that ran until October 2011 in the East and West Midlands.
It found offenders on lie detectors made twice as many admissions about contacting victims or entering an exclusion zone than without.
Offenders also reported that the tests helped them to better manage their own behaviour, according to the government.
