This section has effect for providing rights of appeal against sentence when a person is dealt with by the Crown Court (otherwise than on appeal from a magistrates' court) for an offence of which he was not convicted on indictment.
The proceedings from which an appeal against sentence lies under this section are those where an offender convicted of an offence by a magistrates' court—
appears or is brought before the Crown Court to be further dealt with for the offence.
An offender dealt with for an offence before the Crown Court in a proceeding to which subsection (2) of this section applies may appeal to the Court of Appeal against any sentence passed on him for the offence by the Crown Court.
For purposes of subsection (3)(a) of this section and section 11 of this Act, any two or more sentences are to be treated as passed in the same proceeding if—
and consecutive terms of imprisonment or detention and terms which are wholly or partly concurrent are to be treated as a single term
If by virtue of an order made under section 14 of the Criminal Justice Act 1982, the term of 4 months specified in section 4 of that Act is increased to a term of 6 months or more, subsection (3)(a) above shall have effect, for so long as the term so specified is 6 months or more, as if after the word "more" there were inserted the words "or an order for his detention in a detention centre for a term of 6 months or more has been made under section 4 of the Criminal Justice Act 1982".
