A legal concept which means that a person can be convicted of a crime, if they planned a crime with others or were present and helped or encouraged others committing the crime, even though they might not take part in the actual act that they are charged with.
The law on joint enterprise has recently changed, read our legal update on the Supreme Court judgment of R v Jogee; Ruddock v The Queen (Jamaica) [2016] UKSC 8 here.
This change in the law will only affect a small number of cases where people have been convicted under the joint enterprise principle. The Court of Appeal will only allow an appeal out of time where there has been a serious injustice. If you, or someone you know, may have been affected by this the first step will be to find a criminal solicitor or barrister who can advise on a criminal appeal.
