Subject to the exceptions in s 36 of the Criminal Justice Act 1988 and s 29 of the Criminal Appeal Act 1968, the only power which the Court of Appeal, Criminal Division, had to interfere with an appellant’s sentence was that contained in s 11(3) of the 1968 Act so that on an appeal against an extended sentence which had been wrongly imposed the appellate court was not bound by the mandatory provisions of ss 225 and 226 of the Criminal Justice Act 2003 to impose an indeterminate sentence.
