This was its response to a 1999 referendum, supported by 92 per cent and asking: "Should there be a reform of the justice system placing greater emphasis on the needs of victims, providing restitution and compensation for them and imposing minimum sentences and hard labour for all serious violent offences?"
That wording should never have got past, or even before, the parliamentary process, for whatever part the public really wanted was never clear.
It's a fair bet, however, it had more to do with victim needs than over-populating prisons, which seems to cost us all a bit more than it would to pursue the preventive goal of equitable levels of housing and employment for all.
Thus, prison reform is itself just part of the debate of social justice or what ever else it might be called, depending on the rationale.
