1For most people, courts-martial take place during wartime, dealing with matters such as desertion, cowardliness, and dereliction of duty. However they can be used in peace time to try serious criminal offences under civilian law. This week Frontline looks at the case of army medic Staff Sergeant Ian Barnes and a New Zealand Army Major who went through three courts martial before Army Justice decided their fate. The year long progress led defence lawyers to question whether military law should have been used. The pair were charged with sexually violating patients while on duty at Waiouru army hospital. Normally these charges would be held in the High Court. The case made legal history of being the longest court-martial since World War Two.
