120.—(1) In section 21(1) of CMAA 1968 (appeal against finding of not guilty by reason of insanity) the reference to the Court Martial includes a court-martial.
(2) In relation to an appeal brought by virtue of paragraph (1), the references to the Court Martial in section 22(2) and (3A) of CMAA 1968 are to be read as references to the court-martial.
(3) Paragraph (4) applies, and section 22(3) of CMAA 1968 does not apply, where the Appeal Court substitutes a finding of guilty of an offence for a finding by court-martial of not guilty by reason of insanity.
(4) The Appeal Court shall have the like powers of sentencing the appellant, and other powers, as the Court Martial would have had if Parts 1 to 13 of AFA 2006 had been in force and that court had convicted the appellant of the offence on the date when the court-martial found him not guilty by reason of insanity; and section 17 of CMAA 1968 applies as in the case of a sentence passed by the Appeal Court under article 112, 113, 114 or 117.
