IN Scotland and across the UK, social justice campaigners, human and civil rights groups, religious organisations, many senior past and present criminal justice professionals, academic experts and charities working with offenders and ex-offenders are coming together to make the case for an end to the current blanket ban on voting by all convicted prisoners.

We make powerful arguments about the moral case for an alternative approach. We have set out substantial concerns about the practical impact and arbitrary effects of excluding all convicted prisoners without exception from the democratic process, and in particular from next year's referendum. The Government responds simply: "The Scottish Government does not agree that convicted prisoners should be able to vote while they are in prison."

Throughout the passage of the bill, the Deputy First Minister has given repeated reassurances that "Parliament will decide" on this issue. The speed with which this issue has come up in the Scottish Parliament means the political parties in Scotland have not had the chance for a full internal debate on prisoner voting and the issue was not, understandably, included in any of the 2011 party manifestos. There are significant challenges to equity and social justice raised by applying a blanket ban on voting by all convicted prisoners at the referendum on Scottish independence.
