This short film is aimed at assisting solicitors and case workers who are advising on an appeal against a criminal conviction. It provides an overview of how to identify potential grounds of appeal (criticism of trial lawyers, fresh evidence and errors in the summing up), and gives practical guidance on how to prepare the case. Joel Bennathan QC and Paul Taylor are both members of the Doughty Street Appeals Unit and have both written and lectured widely in these areas as well as been involved in preparing and presenting many appeals.
