What are the anti-slavery provisions of the Coroners and Justice Act 2009?

The criminal offence of holding someone in slavery or servitude, or requiring him or her to perform forced or compulsory labour, was introduced on 6 April 2010 by s.71 of the Coroners and Justice Act 2009. In order for an employer to be found liable for the offence, it must know, or ought to know, that the arrangement was oppressive and not truly voluntary. Those found guilty of the offence could face a fine and/or a maximum of 14 years in prison.
