From the Times article I linked to (wrongly assuming people would read it).
'Other changes include a new power for the courts to impose stalking protection orders, which ban suspects from going within a certain distance of their alleged victims or contacting them.
Judges will be given the power to impose an order on an individual even after an acquittal if there is enough evidence to suggest that they are still a risk to the victim. The orders will also compel offenders to attend a perpetrator programme to address the root causes of their behaviour.
Currently, it is up to the police to apply to magistrates for a stalking protection order — a civil order which it is a criminal offence to breach. Prosecutors cannot apply. This has led to some convicted stalkers continuing to contact their victims from prison, because the courts have no ability to impose such orders at the time of conviction or sentencing.
The bureaucratic hurdles involved in asking the police to make an application after conviction often leads to a delay in implementing the orders or a failure to do so at all.'
