I SEE from the Scottish Legal News that Lady Stacey is to preside over a high-powered debate on the abolition of corroboration organised by the Scottish Association for the Study of Offending.

The outcome will be academic since Lord Carloway already has the green light – as ever, the devil will be in the detail.

History will show that the genesis of the destruction of our criminal justice system was the appointment of career prosecutors as law officers: beginning with (now) Dame Elish Angiolini QC as Solicitor General and continuing with a succession of senior members of Crown Office and Procurator Fiscal Service (COPFS) since who have become and will remain Lord Advocate and Solicitor General for the foreseeable future.

This has led to the unholy, unhealthy alliance of law officers and law makers: Kenny MacAskill and Frank Mulholland, in the same bed. There is no separation of powers. Constitutionally the system now is morally and mortally flawed.

The fall-out from Cadder led to the knee-jerk Cadder Reforms. Ms Angiolini's furore about lack of convictions in rape cases, many of which should never have been raised in the first place, led Mr MacAskill to appoint Lord Carloway to consider whether the law should be amended to abolish the need for corroboration. The current Lord Advocate wants to do away with the accused's right to silence and the logical follow-on from that will be to make the accused a compellable witness. Will the next inexorable draconian step be the replacement of the presumption of innocence with that of a presumption of guilt? It's beginning to look that way. And by that time there may be little or no Criminal Legal Aid.
