Andy worked as a busy and successful Court practitioner, ultimately establishing his own practice concentrating on criminal work. Having called at the Bar, he established a busy practice specialising in serious criminal cases before being appointed an Advocate Depute by Lord Rodger of Earlsferry. This post involved decision making in the most serious cases in Scotland and the prosecution of a number of high profile cases, most notably the successful prosecution of HMA v Agutter – attempted murder of his wife by means of atropine introduced into gin and tonic, covering his tracks by contaminating bottles of tonic in general circulation with a lesser concentration of the poison. Andy continues to conduct serious crime defence at the Bar and is also invited to prosecute specific High Court cases as an ad hoc Advocate Depute.
