The Service Prosecuting Authority provides for the independent, efficient and consistent consideration of criminal cases and offences contrary to military discipline. It will initiate prosecutions where justified and conduct fair and thorough proceedings in the service courts of first instance and the service appellate courts, whilst liaising effectively with the police and dealing with prosecution witnesses and victims of crime with care and sensitivity. Whilst maintaining independence from the service chain of command, the Service Prosecuting Authority fulfils its functions in support of operational effectiveness of the Armed Forces throughout the world.
