Derek Ogg QC

Tony Graham QC, director of Optimum Advocates, Mr Ogg’s stable, looked back on his career, noting that he took silk after only 10 years in practice.

“This was a reflection of the impact he made in that decade, and the regard in which he was held by the court,” he said.

He joined Crown Office in 2007, “unusually entering as a senior depute” and was promoted to assistant principal advocate in 2009.

He was also the inaugural head of the National Sexual Crimes Unit.

Mr Graham said: “He was a fearless trial advocate, both as a prosecutor and as defence counsel. He also appeared in many landmark cases in the appeal court, where his name will eternally appear in reports of those cases.

“But there was far more to Derek than his time in wig and gown. Whilst Derek was one of most well-read individuals one could encounter, he was also a man who was full of fun, compassion and ready to assist anyone – colleague or not – in any way he could. He provided an ear to those who needed his wisdom, could put a smile on the face of the sullen, inspire a laugh from those engrossed in sadness, and create a conversation in even the solemnest of rooms. Often, he did all of these things in a self-deprecating way.”

He added: “Glasgow High Court will be an unfortunately quieter place without Derek as he leaves a void uneasy to fill. Those feelings, however, are insignificant compared to those of his family and loved ones, who have lost not just an outstanding colleague and friend, but a much loved partner, brother and uncle. May he rest in peace.”

First Minister Nicola Sturgeon said: “This is dreadful news. Derek was a brilliant advocate and a truly lovely man. He will be deeply missed by so many in his profession and beyond. It was always a pleasure for me to hear from him on issues he felt strongly about, and I will miss his wisdom and good sense.”

Lord Advocate James Wolffe QC said: “Derek was an outstanding advocate, both as a prosecutor and a defender.

“As an advocate depute, as defence counsel, and in other ways, he made a significant contribution to the administration of justice in Scotland.

“I was shocked and very sad to learn of his death.”

Solicitor General Alison Di Rollo QC added: “Derek was an extraordinary talent, whether as the visionary head of NSCU or as a supremely skilled defence advocate, quite simply one of Scotland’s best.

“I too was shocked – and shaken – by the news of his untimely death.

“We are all the poorer for his loss.”

Gordon Jackson QC, Dean of Faculty, commented: “All of us who knew Derek Ogg are deeply saddened by his passing. He was a marvellous advocate but more than that he was a fierce campaigner for his beliefs both on a personal and professional level. He will be greatly missed by everyone at the Faculty.”

John Mulholland, president of the Law Society, said: “The news of Derek’s death will be felt hard by all who knew him. He fought for justice for clients and for equality and inclusion in the legal profession. He will be sadly missed.

“On behalf of members and staff at the Law Society I pass on our condolences to Derek’s family and friends at this time.”
