The 1998 Scotland Act binds Scotland to all UK treaties. Honouring the UK Libya PTA commitment would not have impinged upon the due processes and jurisdiction of Scots law, and would have shifted the public’s ire onto Mr Salmond’s political enemies: the Labour government. I suspect the answer is that, at the time, the independent minded SNP imagined that a release made according to a PTA wouldn’t grab as many international headlines as one made under the compassionate laws of Scotland. I disagree with Alex Massie's view that the SNP's decision was 'sober' and 'rational'. In view of how the government put the SNP in an impossible position, and how long and hard the SNP tried to resist, their last gasp grandstanding was foolish.
