More prisoners will also be released early with electronic tags in a bid to reduce prison overcrowding and the courts will be encouraged to impose more non-custodial sentences.
The proposed Criminal Justice Policy, which has been four years in the making, would be the first of its kind for the Island.
It will be presented to the States by Home Affairs Minister Wendy Kinnard and also includes a plan for a Police Authority – a decade after the principle was first approved by the States.
The new policy is based on nine ‘pillars’ of criminal justice, including intervention, enforcement, prosecution and dealing with offenders.
Other proposals include greater powers to deal with ‘wanted’ migrants from the UK, transferring more UK prisoners out of the Island and introducing a sex offenders register.
