Ben Douglas-Jones appeared for the Crown in a landmark special court (Lord Thomas CJ, Hallett VP and Goss J) hearing of 6 conjoined appeals, led by John McGuinness QC, in the case of Joseph et al.  EWCA Crim 36. It concerned victims of human trafficking charged with offences.
- Whether duress needed to be reassessed in the context of victims of trafficking;
- How to approach the prosecution of victims of trafficking who commit serious offences (such as drug trafficking) less than murder;
- Whether the courts should redefine the approach to the prosecution of victims of human trafficking following the coming into force of the statutory defence to offences of being a victim of trafficking (s45 of the Modern Slavery Act 2015);
- The prosecution of child victims of trafficking (where the CCRC erroneously suggested that the Court of Appeal had misunderstood the law on the basis that the Court in R v Le and R v N  EWCA Crim 189,  QB 379 (in which Ben Douglas-Jones appeared) had looked at compulsion in relation to child victims in the wrong way);
- The relationship between the Competent Authority and the CPS.
