Court of Protection

Gemma writes the Court of Protection updates for LAG with Sophy Miles and Mary-Rachel McCabe, and she regularly provides training on the Mental Capacity Act and the inherent jurisdiction for vulnerable adults.

Examples of notable cases:

  • Successfully persuaded the court following cross-examination of the local authority’s expert that P had capacity to make decisions about her residence, care, and contact with others.

  • Obtained judgment that it was in P’s best interests to have a trial return home with an appropriate package of care, following a fiercely contested hearing.

  • Successfully persuaded the court that P had capacity to make decisions about his residence following years in a care home against his will.

  • Advocated for an independent capacity assessment on P’s behalf, contested by all other parties, to which the court acceded and resulted in P being found to have capacity to make the welfare decisions in issue.

  • Achieved a move to an alternative care home in P’s best interests after years of family members pursuing a move.

The Court of Protection is a unique jurisdiction regularly requiring discussions between parties to work in P’s best interests. As well as being experienced in witness handling and making complex legal submissions where required, Gemma is adept at chairing discussions and has represented at mediation.


Gemma is a mediator and practising barrister. She has a holistic approach to dispute resolution, combining her academic knowledge from her LLM Masters in Human Rights & Conflict Resolution with her practical legal experience.

Gemma trained with the Society of Mediators, is now a member, and participated in their Free Mediation Project in the summer of 2022. Before being called to the Bar, she worked with charitable and non-profit organisations including in an occupied territory and, separately, with the UNHCR.

Gemma has extensive experience of negotiations in court proceedings, chairing round-table meetings, and facilitating productive discussions between parties. She has practised in many different courts and across a wide range of legal issues, including: mental capacity law, mental health law, inquests, public law, social security, criminal law, employment law, housing, actions against public bodies, and human rights law. She has experience of independent investigations, and engaging participants in difficult dialogues. Now a specialist in the unique jurisdiction of the Court of Protection, which often involves more time negotiating than in court, Gemma is acutely aware that effective discussions can be the key to resolving protracted disputes. Having also represented parties at mediation, she appreciates the perspectives of individuals approaching alternative dispute resolution and has seen the benefits of mediated settlements from all sides. 

Gemma brings her experience as a practising barrister to her role as a mediator whilst maintaining neutrality and helping participants through the process. She is confident in the benefits of mediation for a wide array of legal issues and accepts instructions to facilitate discussions across many disputes.
