law: Armed Forces Tribunal Act 2007 
  16. Re-trial
  1.  
  
    Except
  
  as provided by this Act, where the conviction of a person by court martial for
  
  an offence has been quashed, he shall not be liable to be tried again for that
  
  offence by a court martial or by any other Court.
  2.  
  
    The
  
  Tribunal shall have the power of quashing a conviction, to make an order
  
  authorising the appellant to be retried by court martial, but shall only
  
  exercise this power when the appeal against conviction is allowed by reasons
  
  only of evidence received or available to be received by the Tribunal under
  
  this Act and it appears to the Tribunal that the interests of justice require
  
  that an order under this section should be made:
  Provided that an
  
  appellant shall not be retried under this section for an offence other than-
  a.   the offence for which
  
  he was convicted by the original court martial and in respect of which his
  
  appeal is allowed;
  b.   any offence for which
  
  he could have been convicted at the original court martial on a charge of the
  
  first-mentioned offence;
  c.   any offence charged
  
  in the alternative in respect of which the court martial recorded no finding in
  
  consequence of convicting him of the first-mentioned offence.
  1.  
  
   
  2.  
  
   
  3.  
  
    A
  
  person who is to be retried under this section for an offence shall, if the
  
  Tribunal or the Supreme Court so directs, whether or not such person is being
  
  tried or retried on one or more of the original charges, no fresh investigation
  
  or other action shall be taken under the relevant provision of the Army Act,
  
  1950 (46 of 1950) or the Navy Act, 1957 (62 of 1957) or the Air Force Act, 1950
  
  (45of 1950) as the case may be, or rules and regulations made there under, in
  
  relation to the said charge or charges on which he is to be retried.
