Book excerpt: Available Open Access under CC-BY-NC licence Effective participation in court and tribunal hearings is regarded as essential to justice, yet many barriers limit the capacity of defendants, parties and witnesses to participate. Featuring policy analysis, courtroom observations and practitioners’ voices, this significant study reveals how participation is supported in the courts and tribunals of England and Wales. Including reflections on changes to the justice system as a result of the COVID-19 pandemic, it also details the socio-structural, environmental, procedural, cultural and personal factors which constrain participation. This is an invaluable resource that makes a compelling case for a principled, explicit commitment to supporting participation across the justice system of England and Wales and beyond.
