Experience & expertise

Angus works in a wide range of fields including clinical negligence, employment, Court of Protection, inquests, police and public and regulatory law. His knowledge of the law in many specialist areas allows him to bring a wide perspective to complex cases. He has a particular reputation for sensitivity in dealing with clients involved in difficult litigation.

He has a background in commercial law, having been instructed in diverse contractual disputes ranging from construction arbitrations to large scale banking disputes. Angus was counsel in the leading House of Lords authority on “agreements to agree”, Walford v Miles. He maintains a practice in contractual and commercial disputes, acting for example in a very substantial dispute between an advertiser and a media owner.

Recent important cases include Henderson v Dorset Healthcare, the leading case on the law of illegality in clinical negligence claims. Angus acted for the successful Respondent in obtaining the dismissal of an appeal to the Supreme Court by a psychiatric patient who had killed her mother. The Supreme Court adopted Angus’ arguments in dismissing the appeal. Angus led Cecily White in this case.

Angus has practised in the field of employment law for many years. In Aubrey v Northumbria Police, the widely publicised discrimination claim in which Angus acted on behalf of the Chief Constable of Northumbria Police. Ms Aubrey was a solicitor and former Director of Legal Services, who after being dismissed for gross misconduct claimed sexual harassment. The hearing involved allegations of sexual misconduct in the force which were widely reported in the national press. All Ms Aubrey’s claims were rejected by the Employment Tribunal, including her claims for sex discrimination, harassment, victimisation, disability discrimination, whistleblowing and unfair dismissal. Angus led Aaron Rathmell in this case.

Angus was counsel representing the employee in the House of Lords’ decision in Skidmore v Dartford and has represented both employers and employees in cases involving injunctions in the High Court, such as Kircher v Hillingdon. He successfully represented the employer in Chan v Barts, a very large whistleblowing claim. He continues to represent parties involved in internal disciplinary hearings.

Angus has chaired a number of employment inquiries relating to sexual misconduct by employees, serious surgical and other medical incompetence and bullying and harassment by senior employees. He also advises as to police pensions.

Angus has been instrumental in developments in the law relating to the boundaries of the duty in care in tort owed by doctors to third parties. He acted in the seminal cases of JD v East Berkshire (House of Lords’ decision as to whether doctors are liable for negligent diagnoses of sexual abuse); Palmer v Tees Health Authority (Court of Appeal’s decision as to whether doctors owed duties to mother of child murdered by psychiatric patient) and Selwood v Durham County Council (claim by social worker against NHS as a result of being stabbed by a psychiatric patient). In Griffiths -v- Norfolk and Suffolk NHS Foundation Trust in 2018 he secured the dismissal of the claims of negligence by the family of Mary Griffiths, who was killed by John McFarlane in the “bolt gun murder”.

Angus acts for both claimants and defendants. In 2020 he acted for the successful Claimant, a severely brain damaged child, in NKX v Barts Health NHS Trust, a case in which breach of duty and causation were disputed by the Defendant. Angus cross examined a large number of midwives and experts called by the Defendant and liability was established. The quantum element of the case led to the Claimant receiving one of the highest periodical payments ever awarded, £700,000 per annum. Angus led Eleanor Morrison in this case. In 2018 he acted for the Claimant in Cerys Clements -v- Imperial College Healthcare NHS Trust, the case involving the baby who suffered brain damage during breastfeeding.  He also represented the injured Claimant in the important Court of Appeal decision relating to causation and quantum in Reaney v University Hospital of North Staffordshire NHS Trust. In the Winterbourne View proceedings he is defending a number of multi-million pound claims in substantial litigation which has repercussions for the NHS generally.

Angus also has particular expertise in the Court of Protection. He was counsel instructed by the Official Solicitor in the seminal decision of An NHS Trust v A, the case involving an Iranian hunger striker. The case identified a new “gap” in the Mental Capacity Act 2005. Angus’ submissions enabled the Court to fill that gap. He also appeared in DE, a ground-breaking case in which a court authorised an enforced vasectomy upon an adult patient with learning disabilities for the first time.

In the field of inquests, Angus frequently represents Interested Persons in substantial Article 2 ECHR inquests. He was instructed by an NHS Trust in the inquest relating to the death of Jane Antoniou (R(Antoniou) v North West London NHS Foundation Trust). This was later the subject of an application for judicial review in the Administrative Court. Angus successfully defended the claim for breach of Article 2 ECHR in the Administrative Court.

Angus is also instructed in inquiries. For example, the Redfern Inquiry was an inquiry into human tissue analysis in UK nuclear facilities established by the Secretary of State for Trade and Industry. Angus successfully represented a doctor summoned to provide material to the Inquiry, obtaining declarations from the Court limiting disclosure of confidential medical records to and by the Inquiry.

Angus is regularly instructed in difficult cases in the General Medical Council and other regulatory tribunals. He has been instructed in some of the landmark regulatory cases in the Administrative Court including the seminal case of Cohen v GMC which has been credited as turning the regulatory tide in favour of doctors. In 2016 he represented a highly distinguished medical professor who had had his licence to practise revoked. Following an appeal, in which Angus represented the professor, the GMC reinstated the professor’s licence.

In General Medical Council v Stone Angus acted for the doctor in an appeal by the GMC against the sanction of suspension. The judge, Jay J, described Angus’ submissions as “well-structured, powerfully delivered and astute.” In GMC v Monro, a very well known case in medical circles, Angus successfully defended a well known practitioner against an allegation of impairment of fitness to practise in diagnosing lead toxicity. Following his cross examination of experts called on behalf of the prosecution, the GMC found that the doctor’s fitness to practise was not impaired.

The cases cited here are illustrative examples only. Full details of Angus’s cases and work of note are set out in his specialist profiles.

The focus of my professional life is getting the judge or tribunal to empathise with my clients. In fact the challenge of persuading a tribunal to side with my client is the biggest joy of this job for me. When I first get instructed I like to digest the detail, but to emerge from that process with a strategy for persuading the decision-maker to see things our way.

I don’t underestimate the value of warmth and sensitivity in the law. These qualities are sometimes overlooked in an advocate. But they are important. First and foremost, they help in establishing a relationship with both the lay and the professional client. Second, they help to work together as a team. Last, but definitely not least, they help to persuade the judge or tribunal.

My second goal is learning. I have never had a day of boredom as a barrister. There is something new to learn from every case, sometimes the law, more often the medical or other professional practice. Learning and communicating new ideas is another privilege of the job.

“I have never had a day of boredom as a barrister.”

Working in so many different fields of the law allows me to bring a wide perspective to bear. Each of the fields in which I work bring skills which can be applied in other fields. Acting in clinical negligence claims has enabled me to develop skills in cross-examination of experts. Acting for police forces in large discrimination claims has enabled me to marshal complex law and cross-examine on the facts. Working in inquests has taught me the value of sensitivity. Complex Court of Protection cases have required an ability to persuade by being robust (with some judges). Working in public law has meant I have developed legal knowledge in a wide range of differing spheres.

But what I like best is persuading.
