"it would be wrong, in my opinion, to disregard the
practical situation that the appellant had already
served a substantial period of imprisonment in
Queensland for offences so closely related in time
and character to the Sydney offences. ...
... where there has been a lengthy postponement,
whether due to an interstate sentence or otherwise,
fairness to the prisoner requires weight to be
given to the progress of his rehabilitation during
the term of his earlier sentence, to the
circumstance that he has been left in a state of
uncertain suspense as to what will happen to him
when in due course he comes up for sentence on the
subsequent occasion, and to the fact that
sentencing for a stale crime, long after the
committing of the offences, calls for a
considerable measure of understanding and
flexibility of approach - passage of time between
offence and sentence, when lengthy, will often lead
to considerations of fairness to the prisoner in
his present situation playing a dominant role in
the determination of what should be done in the
matter of sentence; at times this can require what
might otherwise be a quite undue degree of leniency
being extended to the prisoner."
