The proposed date of sentencing can be monitored on the Scottish Court Service website.
From the list which the link below brings up, click on 'High Court of the Justiciary' and then on the link to 'Deferred Sentencing' from the new list displayed.
You will be given access to a Word document which details the miscellaneous business of the High Court on a weekly basis. For example, the document for the week commencing 4th August 2003 shows that Lord Reed was due to pass sentence on Robertson on 5th August (now further deferred as stated by Danny).
I guess checking each week for his name will give a heads up to anyone who has an interest in seeing what justice will bring to him.
