Giles has particular expertise in the law of speciality training for doctors and dentists, an area in which few barristers practise. He advises and represents trainees, and has acted for training bodies, on ARCP outcomes and appeals, removal from or extension of training, the decisions of deaneries and NHS England (formerly Health Education England), CCT and CESR applications and the GMC's specialist register, and the fitness-to-practise and disciplinary processes of universities and medical schools. He also acts for trainees facing MHPS proceedings in the Trusts where they are placed.

He is currently advising and acting in a number of such cases. 

The work is urgent, technical and career-defining: ARCP appeals run to short deadlines, the Gold Guide and the curricula are detailed, and the interaction between training decisions, employment rights and GMC registration is often misunderstood by the bodies making the decisions.

Typical instructions

• ARCP Outcome 3, 4 and 10 decisions, appeals and re-appeals
• removal from a training programme, extension of training and remediation plans
• disputes with deaneries, training programme directors and educational supervisors
• CCT and CESR applications and GMC specialist registration
• university and medical school fitness-to-practise proceedings
• judicial review of training decisions
• Foundation and speciality trainees facing MHPS or disciplinary proceedings in their placement Trust
